分泌性中耳炎的诊断标准

This is an update of the 2015 Guidelines developed by the Japan Otological Society and Oto-Rhino-Laryngeal Society of Japan defining otitis media with effusion (OME) in children (younger than 12 years old) and describing the disease rate, diagnosis, and method of examination. Recommended therapies that received consensus from the guideline committee were updated in consideration of current therapies used in Japan and based on available evidence. METHOD Regarding the treatment of OME in children, we developed Clinical Questions (CQs) and retrieved documents on each theme, including the definition, disease state, method of diagnosis, and medical treatment. In the previous guidelines, no retrieval expression was used to designate a period of time for literature retrieval. Conversely, a literature search of publications from March 2014 to May 2019 has been added to the JOS 2015 Guidelines. For publication of the CQs, we developed and assigned strengths to recommendations based on the collected evidence. RESULTS OME in children was classified into one group lacking the risk of developing chronic or intractable disease and another group at higher risk (e.g., children with Down syndrome, cleft palate), and recommendations for clinical management, including follow-up, is provided. Information regarding management of children with unilateral OME and intractable cases complicated by adhesive otitis media is also provided. CONCLUSION In clinical management of OME in children, the Japanese Clinical Practice Guidelines recommends management not only of complications of OME itself, such as effusion in the middle ear and pathologic changes in the tympanic membrane, but also pathologic changes in surrounding organs associated with infectious or inflammatory diseases.

MATERIAL AND METHODS 361 children at age from 11 months to 18 years with otitis media with effusion (OME) were inspected after tympanostomy during 2013-2018 years. Treatment was carried out in accordance with the stages of OME: secretory, mucous, fibrous. The main diagnostic methods were: otoscopy, tympanometry, endoscopy, computed tomography. Surgical treatment may be required already at the secretory stage of the disease, as well as in all cases with mucous and fibrous stages of OME. RESULTS In children with recurrences of OME and in patients with congenital cleft lip and palate, it is preferable to use long-wearing ventilation tubes and balloning of the auditory tubes. The effectiveness of surgical treatment of OME was 97.6%. CONCLUSION The authors recommend dispensary observation of patients with OME for 12-24 months.

Otitis media with effusion (OME) is one of the most common childhood diseases. It is recommended to use tympanometry in addition to otoscopy and/or pneumatic otoscopy for the diagnosis and follow-up of OME. Clinitians are using Wideband absorbance (WBA), which is one of the methods of evaluating the middle ear in the diagnosis of OME, more widely. The relationship between the changes in the examination findings obtained by otoscopy and pneumatic otoscopy and the findings of WBA in the monthly follow-ups performed during the three-month period of children diagnosed with OME, was examined. In the study, 48 ears of 26 individuals aged 24–71 month who were diagnosed with OME were evaluated. Otoscopy, pneumatic otoscopy, 226 Hz tympanometry and WBA measurements were performed at the initial, first, second and third month examinations. The relationship between the difference between consecutive measurements was examined because it was thought that consecutive measurements might be more significant in the relationship between measurements. The Spearman test was used to determine whether there was a relationship between WBA and otoscopic and pneumatic otoscopic examination results. For assessing parameters where there was a significant difference between the groups compared, the variables were assessed using Kruskal-Wallis analysis of variance. The Dunn test was used for post hoc testing. The change observed with both otoscopy and pneumatic otoscopy between the initial and first month control could not be adequately determined by 226 Hz tympanometry, but the change in the amount absorbance at 2520 Hz and 3175 Hz was moderately correlated with the examination findings. However, it was observed that the change between the first and the second follow-up examinations was significant at the frequency range of 226–630 Hz in WBA and the change between the second and third months was significant at the frequency range of 226–4000 Hz in WBA. The findings obtained in the study show that, 226 Hz tympanometry may be insufficient to reflect the change in examination findings while WBA can provide more detailed information to support the examination findings during the follow-up period as well as the diagnosis of OME.

Objectives Surgical management of children with chronic otitis media with effusion (OME) includes tympanostomy tube insertion or adenoidectomy, alone or with myringotomy and tube insertion. The aim of this study was to compare the effectiveness of transoral microdebrider endoscopic-assisted adenoidectomy (TOMEA) and traditional adenoidectomy in the management of children with mild hearing loss due to OME and chronic adenoiditis. Methods This prospective, double-blind and controlled study involved 120 consecutive patients aged 4–12 years, who were randomised 1:1 to undergo TOMEA or traditional adenoidectomy under general anesthesia. All the patients underwent a complete otolaryngological examination, including nasopharyngeal fibre endoscopy (NFE), pneumatic otoscopy, otomicroscopy, tympanometry and supraliminar tonal audiometry, upon enrolment, and three and nine months postoperatively. Results There were no statistically significant differences in age or gender distribution between the TOMEA group (mean age, 4.9±1.1 years; 53.3% males) and the traditional adenoidectomy group (mean age, 5.3±0.9 years; 56.7% males). Both procedures led to a significant improvement in choanal patency (P<0.01) and all of the otological and audiological parameters (P<0.01) 3 and 9 months postoperatively, although postoperative NFE showed that the mean percentage of residual choanal obstruction was significantly less in the TOMEA group (P=0.02). There was no significant between-group difference in the percentage of children with tympanic membrane changes, but the postoperative prevalence of children with a type B tympanogram was significantly lower in the TOMEA group after 3 (15.0% vs. 31.7%, P=0.05) and 9 months (18.3% vs. 38.3%, P=0.02), as was the percentage of children with mild conductive hearing loss (3.3% vs. 23.3%, P<0.01; and 8.3% vs. 28.3%, P<0.01). Conclusion Although both TOMEA and traditional adenoidectomy are effective in treating children with mild hearing loss due to adenoidal hypertrophy and OME, the former achieves the greater reduction in residual adenoidal hypertrophy and better audiological outcomes.

Background: Otitis media with effusion (OME) is a middle ear condition characterized by the accumulation of serous fluid. It is common, though not exclusive; among children with its attendant developmental consequence if missed or untreated in early life. OME could be managed surgically, pharmacologically, or physiologically. EarPopper is a medical device developed for physiologic management of OME, Eustachian tube dysfunction, and related problems. We aim to ascertain the suitability/efficiency of EarPopper® device for the treatment of OME in our setting. Methodology: This is a prospective interventional study of volunteers diagnosed with OME from four (4) medical centers in Abuja. Pneumatic otoscopy, video-otoscopy, tympanometry, and pure-tone audiometry were done to confirm the diagnosis. Serial EarPopper sessions were performed twice weekly for 2–12 weeks, and outcome was assessed using patients' reports. The reports include the EarPopper scoring system (ESS) and audiometric parameters (before and after therapy). Results: Forty-five patients (17 males and 28 females) aged between 3–56 years were enrolled. Thirty-five were diagnosed with bilateral OME and 10 unilateral. All patients had Type-B tympanometry tracing with mild-to-moderate conductive hearing losses and ESS of between 2.45% and 84%. Out of the 45 participants, 32 (71.1%) completed the treatment, whereas 13 (28.9%) were lost to follow-up. Duration of EarPopper treatment ranged from 2 to 12 weeks. The outcome revealed improvement in 26/32 (81.3%) with significant reduction in ESS (1% to 9.8%). Six patients 6/32 (18.9%) had persistence symptoms. These 18.9% had the propensity to progress to chronic OME. Conclusion: This study highly suggests good prospect in using EarPopper for the management of OME among Africans.

Background Down syndrome (DS) is associated with a high incidence of ear pathologies and hearing loss. There is a paucity of information on the audiology of people with DS particularly those in special schools in Nigeria. This study aimed to compare pneumatic otoscopy with tympanometry for middle ear screening and pure tone audiometry (PTA) with distortion product otoacoustic emission (DPOAE) for hearing screening in the different age groups of people with people DS. Methodology People with DS in two special schools for people with intellectual disability in Surulere, Lagos state were selected based on the schools' record and their phenotype. Otoscopy, pneumatic otoscopy, tympanometry, screening PTA and screening DPOAE were performed on the subjects. Results 52 subjects aged 6 to 36years and an M: F ratio of 1.5:1 were studied. 82.7% of subjects had wax impaction. The prevalence of otitis media with effusion (OME) by pneumatic otoscopy was 57.8% and 40.2% by tympanometry and the same number of subjects performed both tests successfully. Screening PTA and DPOAE were successfully performed on 32.7% and 94.2% of the subjects respectively. Fail rate of 29.4% by PTA and 65.3% by DPOAE were recorded. Conclusion Regular ear check-up in people with DS is essential for the detection and treatment of ear wax, OME and hearing impairment which is highly prevalent in them. Pneumatic otoscopy is recommended for the detection of OME in all the age groups. Screening PTA and OAE are recommended for adults and children and non-cooperative adults hearing screening respectively.

Chronic OME, which arises from a complex series of inflammatory events in the middle ear, affects approximately 5% to 30% of children. The mean duration of MEE is 16 to 20 weeks during the first 2 years of life. This condition is diagnosed best with pneumatic otoscopy and tympanometry. The risk of chronic OME is increased by environmental factors and characteristics of the child, including disease history. Approximately 70% of MEE are culture-positive, with approximately 50% of these yielding S pneumoniae, H influenzae, or M catarrhalis. However, antibiotic treatment of acute otitis media and OME has only a minimal effect on the long-term resolution of MEE. Research has shown that 70% of children who have chronic OME suffer mild-to-moderate hearing loss, so a child who has bilateral MEE for 3 months should undergo hearing evaluation. If the child has hearing impairment, referral to an otolaryngologist for myringotomy and tympanostomy tube insertion is a treatment option that the AHCPR recommends after 4 months of effusion with hearing loss. Sequelae of chronic OME include deficient expressive language and poorer attention skills due to the temporary hearing loss associated with OME, high-frequency sensorineural hearing loss, tympanic membrane atrophy, perforation, retraction, atelectasis, and cholesteatoma.

The specific aims of this prospective survey were to determine the accuracy of traditional diagnostic tools, such as pneumatic otoscopy, otomicroscopy, and tympanometry, and evaluate the usefulness of myringotomy as a diagnostic method; also to determine the significance of myringotomy in treating otitis media with effusion (OME). The status of middle ear of 51 children (85 ears) from November 2002 to February 2003 was examined using pneumatic otoscopy, otomicroscopy, and tympanometry, and the presence/absence of middle ear effusion was confirmed by myringotomy. The otomicroscopy was the most sensitive and specific one among three diagnostic tools. But, it had some false positive cases. This study failed to show the therapeutic efficacy of myringotomy. Otomicroscopy seems to have the potential to become the standard for diagnosis of OME and for validation of pneumatic otoscopy in children. However, when otoscopic, otomicroscopic findings and tympanogram of suspected ear show poor correlation, myringotomy can be used to confirm the presence of OME, as the diagnostic modality. As the therapeutic modality, we think that it is proper to limit indications of myringotomy to some selected cases.

BackgroundTympanometry and pneumatic otoscopy are recommended for diagnosis of otitis media, but are not frequently used by general practitioners (GPs). We examined how, after targeted short training, GP diagnosis and management of childhood ear disease was changed by the addition of these techniques to non-pneumatic otoscopy. We further explored factors influencing the uptake of these techniques.MethodsBetween 2011 and 2012, we used a crossover experimental design to determine associations between tympanometry and pneumatic otoscopy and the GP diagnosis and management of ear disease in children aged 6 months to 6 years. GPs recorded a diagnosis and management plan after examining ears using non-pneumatic otoscopy, and another after using either tympanometry or pneumatic otoscopy. We compared diagnosis, prescription of oral antibiotics and planned GP follow-up at these two steps between the tympanometry and pneumatic otoscopy groups. We interviewed participants about their views regarding these techniques and analysed these data thematically.ResultsThirteen GPs recorded 694 ear examinations on 347 children: 347 examinations with non-pneumatic otoscopy; then 196 using tympanometry; and 151 using pneumatic otoscopy. Tympanometry was more likely to be associated with changes in diagnosis (χ 2 = 28.64, df 1, p < 0.001) and planned GP follow-up (χ 2 = 9.24, df 1, p < 0.01) than pneumatic otoscopy. Change in oral antibiotic prescription was no different between the two techniques. GPs preferred tympanometry to pneumatic otoscopy, but cost was a barrier to ongoing use. Pneumatic otoscopy was considered the more difficult skill. GPs were not convinced that the increased detection of middle ear effusion afforded by tympanometry and pneumatic otoscopy resulted in benefit to general practice patients.ConclusionTympanometry was more likely than pneumatic otoscopy to change GP diagnoses and follow-up plans of childhood ear disease. Tympanometry may require less training than pneumatic otoscopy. GPs preferred tympanometry due to ease of use and interpretation; however, perceived high cost inhibited their intent to use it in the future. Training, cost and perceived lack of patient benefit are barriers to the use of tympanometry and pneumatic otoscopy in general practice.

Objectives: we aim to assess the contribution of the EarPopper device to hearing in children with middle ear effusion (MEE). Methods: The study has three parts, including 1. tympanometry and audiometry before and six weeks after using the EarPopper to evaluate the treatment’s effect over time compared to a control group; 2. tympanometry before and immediately after using the EarPopper to evaluate immediate changes in middle ear pressure (MEP); 3. length of effect 90 min after use to assess pressure fluctuations over time. Results: Part 1 was a follow-up six weeks after using the device, and the patients in the study group that completed the study showed a significant improvement in hearing threshold. The average gain in hearing threshold ranged from 9.1 dB to 14 dB compared to the control group’s max improvement of 1.1 dB. In addition, MEP was significantly improved in the study group, as most Type Bs improved to Type A and C. Part 2 was the tympanometry immediately after using EarPopper and showed the majority of Type Cs turned into Type As. The majority of Type Bs remained unchanged. Part 3 was a follow-up 90 min after use; Type Cs that had improved to Type A demonstrated a decrease in pressure and return to negative pressure. Conclusions: use of the EarPopper device for six weeks is associated with an improved hearing threshold and middle ear status.

Objective The assessment of bone conduction thresholds in patients with conductive hearing loss is not a full measure of the function of the inner ear due to the weakening of the influence of middle ear components on bone conduction. This relationship has been called the ‘Carhart effect’. Methods The retrospective analysis covered 977 patients diagnosed and treated for middle ear diseases from 2010 to 2020. The Carhart effect was considered to be an increase in the bone conduction threshold by a minimum of 10 dB relative to adjacent frequencies. The study was performed with the aim of assessing the presence of the Carhart effect in the course of middle ear diseases in pretreatment analysis. Results The Carhart effect was observed in 532 cases, most often in patients with chronic otitis media and otosclerosis. It was least often observed in patients with otitis media with effusion. In otitis media with effusion, the Carhart effect was more often noted for the frequency of 4000 Hz, in otosclerosis for the frequency of 2000 Hz. In patients with chronic otitis media, this effect for the frequency of 4000 Hz was correlated with the location of inflammatory changes in the attic area. The presence of inflammatory lesions in the oval window area was associated with the presence of the Carhart effect for the frequency of 2000 Hz. Conclusions 1. The frequency of the Carhart effect observed in diseases of the middle ear does not depend on the disease entity but on the type and location of abnormalities in the middle ear. 2. The Carhart effect observed for the frequency of 4000 Hz coexists with the localization of lesions in the range of the malleus and incus, and for the frequency of 2000 Hz, it is partially associated with abnormalities in the range of stapes and oval window.

Background Otitis media with effusion is the most commonly recognized condition in childhood. Chronic otitis media with accompanying hearing loss is particularly unfavorable in the first years of the child’s life because it can not only permanently damage the structure of the middle ear, but also adversely affect speech development and intellectual abilities in the child. Material/Methods This study, from a single center in Poland, included 201 children (372 ears) requiring surgical treatment due to otitis media with effusion. The condition was diagnosed by an ear, nose, and throat specialist, and each patient had a hearing test performed. The control group consisted of 21 patients (42 ears) with negative outcomes following an audiological interview. Results Among all of the patients enrolled in the study, a normal tympanometry result was found in 60.6% of ears, and otoemission occurred in 63.3% of ears. The average hearing threshold in the study group was 22.01 Hz in the 500 Hz frequency range, while they were 16.76 Hz, 12.72 kHz, and 14.78 kHz for the corresponding 1 kHz, 2 kHz, and 4 kHz ranges, respectively. Conclusions Ventilation drainage is an effective treatment for otitis media with effusion. The presence of genetic disease has the greatest impact on the course of otitis media. These patients most often require reinsertion of a ventilation tube.

INTRODUCTION Otitis media with effusion is common middle ear mucosa disease that can cause hearing loss in children. Adenoid hypertrophy can cause recurrent acute otitis media in addition to otitis media with effusion as a result of eustachian tube dysfunction and primary infection focus. The aim of this study was to investigate the effect of adenoid hypertrophy on the hearing threshold in children suffering from otitis media with effusion. METHODS Children of school age with otitis media with effusion were included in the study. The size and location of the adenoid tissue were determined by examination with a flexible endoscope. Four adenoid size groups were determined according to the percentage of choanal closure. The coverage was 0-25% in the first group, 26-50% in the second group, 51-75% in the third group and 76-100% in the 4th group. The location of the adenoid tissue in the nasopharynx was divided into three groups. In group A, the adenoid tissue was not in contact with torus tubarius. In group B, the adenoid tissue was in contact with the torus tubarius but did not cover it. In group C, the adenoid tissue covered the torus tubarius completely. Bone and air conduction thresholds were determined using standard procedures. The statistical relationship between the size and location of adenoid tissue and the hearing thresholds was investigated. RESULTS The study was conducted with the 88 ears of 50 children aged 5-15 years. The median values of mean air conduction thresholds at 500 Hz, 1000 Hz, and 2000 Hz in the adenoid tissue size groups 1-4 were 22 dB HL, 20 dB HL, 15 dB HL, and 20 dB HL respectively. The median values of the mean air conduction thresholds were 20 dB HL, 20 dBHL and 18 dB HL in the adenoid location group A-C, respectively. No significant correlation was found between the groups (p:0.213) and the relevant hearing values (p:0.670). Type B tympanogram was identified in 46 ears and type C tympanogram in 42 ears. The mean hearing thresholds were significantly higher in the ears with a type B tympanogram in the otitis media with effusion cases. (P < 0.001).There was no significant correlation between the duration of effusion and the adenoid size (p:0.931), adenoid location (p:0.626) and hearing threshold (p:0.815). CONCLUSION We concluded that adenoid tissue size and location have no effect on hearing thresholds and the duration of effusion in otitis media with effusion. We suggest caution before deciding on adenoidectomy in otitis media with effusion cases. Adenoidectomy should not be performed in children over 4 years of age unless there is a definite indication such as nasal obstruction or chronic adenitis.

Surgical intervention for pediatric chronic otitis media with effusion (COME) reverses hearing loss imposed by fluid in the middle ear space. Current recommendations are treatment implementation for bilateral COME, but only treatment consideration for unilateral COME. The latter recommendation could result in unrecognized binaural processing impairment and tinnitus arising from interaural threshold differences. This prospective, cross-sectional study contrasted three cohorts (A, normal hearing and without COME, N = 12; B, bilateral COME, N = 11; and, C, unilateral COME, N = 7) using a portable spatial release from masking (SRM) test protocol and tinnitus loudness measurement. The participant ages ranged from 5.4 to 13.7 years (mean=9) and average pure tone thresholds in the poorer ear of COME cohorts were comparable at ∼30 dB. The unilateral COME cohort showed poorer SRM performance (p = 0.012). Children with greater interaural threshold asymmetry were more likely to have a greater reduction in benefit from spatial release from masking, regardless of COME status or degree of hearing loss (F = 5.1, p = 0.033). Tinnitus prevalence was 71 % in unilateral COME and 55 % in bilateral COME cohorts. Tinnitus loudness was associated with mood symptoms severity and hearing-related quality of life. Early evidence for significant central auditory and tinnitus consequences of pediatric unilateral COME prompts reappraisal of treatment recommendations that call for only consideration of surgical evacuation of middle ear fluid and placement of a tympanostomy tube. Longitudinal studies to examine central auditory function in children with COME that deploy intervention arms will be necessary to support any change to current clinical practice.

Background: Currently, the novel coronavirus (SARS-CoV-2) causes an acute respiratory illness named COVID-19 and is a controversial risk factor for hearing loss (HL). Herein, we aim to describe the associated symptoms and to evaluate hearing function in the COVID-19 pediatric population. Methods: A retrospective cross-sectional observational study was carried out on 37 children who contracted COVID-19 infection with no previous audio-vestibular disorders. Clinical data on the infections were collected, and an audiological assessment of all affected children was performed by using different diagnostic protocols according to their age. Results: Fever, upper respiratory and gastrointestinal manifestations were common presentations of infection. Audiological function was normal in 30 (81.08%) children, while 7 children showed an increased hearing threshold: 6 (16.21%) had transient conductive hearing loss (CHL) due to middle ear effusion and normalized at the follow-up and 1 had sensorineural hearing loss (SNHL). A single child was affected by bilateral SNHL (2.7%); however, he underwent a complete audiological work-up leading to a diagnosis of genetic HL due to a MYO6 gene mutation which is causative of progressive or late onset SNHL. Conclusions: HL needs to be considered among the manifestations of COVID-19 in children, nevertheless, we found cases of transient CHL. The onset of HL during or following COVID-19 infection does not eliminate the indication for maintaining audiological surveillance and audiological work-ups, including genetic diagnosis, to avoid the risk of mistaking other causes of HL.

Abstract Background: Diagnosis and treatment strategies for CP with OME and the timing of ear tube insertion remain controversial. Objectives: To analyze the clinical outcomes of otitis media with effusion in children with incomplete cleft palate after palatoplasty prospectively. Methods: A total of 30 children (10 months–2 years old) with incomplete CP were enrolled in this study and received at least 6 months of follow-up evaluations after palatoplasty. Results: The overall improvement rate of OME was as high as 26% in this group. Average air conduction hearing threshold was significantly better than that before surgery in the 8 patients with improved OME (p < .05). Among the 8 children with improved OME, 7 (87.5%) were found to have middle ear effusion that improved within 6 months after CP repair. There was no significant difference in the improvement rate between the severe degree II group and the mild group. Conclusion: A 6-month follow-up period is recommended. The severity of incomplete CP is not fully related to the function of the eustachian tube. Significance: The overall improvement rate was as high as 26%, and effusion in the tympanic cavity subsided in 7 out of 8 cases within 6 months after the CP repair.

Abstract Introduction Otitis media with effusion (OME) is a leading cause of hearing impairment in children. Therefore, early and proper management is essential. Objectives The objective of this research is to assess the efficacy of intratympanic (IT) steroids injection for management of otitis media with effusion (OME). Methods This study involved 42 children (84 ears) with bilateral OME. We used tympanometry to confirm the childreńs middle ear effusion and pure tone audiometry to determine hearing threshold. We performed myringotomy and inserted ventilation tubes (VTs) bilaterally, followed by a steroid injection of 0.4–0.6 mL methylprednisolone (40 mg/mL) into one randomly selected middle ear. This procedure was followed by once-weekly administration of steroids (0.5 mL methylprednisolone at a concentration of 40 mg/mL) into the middle ear for three consecutive weeks. Results We found recurrent OME after VT alone in nine (21.4%) ears; whereas, after VT combined with steroid administration, we found two (4.76%), with statistically significant difference. We noted tympanosclerosis postoperatively in six (12.9%) ears and in one of the injected ears (2.3%) (p = 0.0484). Otorrhea occurred in eight (19%) ears with VT alone and in three (7.1%) injected ears, with non-significant difference. The duration between VT insertion and its extrusion was 6.6 = 1.1 months for ears with VT alone and 6.95 =1.12 months in injected ears (p = 0.1541 NS). Conclusion IT Steroids injection for treatment of OME is a safe and simple intervention with lower incidence of symptoms recurrence and postoperative complications. Thus, its use in management of OME is recommended.

The incidence and the prevalence rates of otitis media with effusion (OME) are high. However, there is evidence that only a minority of professionals follow the recommendations provided in clinical practice guidelines. For the purpose of improving diagnosis and treatment of OME in children to prevent and/or reduce its impact on children's development, the Commission for the Early Detection of Deafness (CODEPEH) has deeply reviewed the scientific literature on this field and has drafted a document of recommendations for a correct clinical reaction to of OME, including diagnosis and medical and surgical treatment methodology. Among others, medication, in particular antibiotics and corticoids, should not be prescribed and 3 months of watchful waiting should be the first adopted measure. If OME persists, an ENT doctor should assess the possibility of sugical treatment. The impact of OME in cases of children with a comorbidity is higher, so it requires immediate reaction, without watchful waiting.

Accurate diagnosis of otitis media is important to prevent suffering and complications when infection is present, and unnecessary antibiotic use when infection is absent. The usual signs and symptoms of acute otitis media are unreliable guides in infants and young children. Similarly, middle ear effusions may present with little discomfort in older children. We therefore depend on examination of the tympanic membrane with an otoscope to make most diagnoses. This article aims to improve the accuracy of middle ear diagnosis by pneumatic otoscopy. It includes descriptions and photographs of the normal ear drum and illustrates the pathologic changes seen in acute otitis media, long-standing eustachian tube dysfunction and otitis media with effusion.

The clinical practice guideline on otitis media with effusion (OME) provides evidence-based recommendations on diagnosing and managing OME in children. This is an update of the 1994 clinical practice guideline "Otitis Media With Effusion in Young Children," which was developed by the Agency for Healthcare Policy and Research (now the Agency for Healthcare Research and Quality). In contrast to the earlier guideline, which was limited to children 1 to 3 years old with no craniofacial or neurologic abnormalities or sensory deficits, the updated guideline applies to children aged 2 months through 12 years with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The American Academy of Pediatrics, American Academy of Family Physicians, and American Academy of Otolaryngology-Head and Neck Surgery selected a subcommittee composed of experts in the fields of primary care, otolaryngology, infectious diseases, epidemiology, hearing, speech and language, and advanced-practice nursing to revise the OME guideline. The subcommittee made a strong recommendation that clinicians use pneumatic otoscopy as the primary diagnostic method and distinguish OME from acute otitis media. The subcommittee made recommendations that clinicians should 1) document the laterality, duration of effusion, and presence and severity of associated symptoms at each assessment of the child with OME, 2) distinguish the child with OME who is at risk for speech, language, or learning problems from other children with OME and more promptly evaluate hearing, speech, language, and need for intervention in children at risk, and 3) manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known) or diagnosis (if onset is unknown). The subcommittee also made recommendations that 4) hearing testing be conducted when OME persists for 3 months or longer or at any time that language delay, learning problems, or a significant hearing loss is suspected in a child with OME, 5) children with persistent OME who are not at risk should be reexamined at 3- to 6-month intervals until the effusion is no longer present, significant hearing loss is identified, or structural abnormalities of the eardrum or middle ear are suspected, and 6) when a child becomes a surgical candidate (tympanostomy tube insertion is the preferred initial procedure). Adenoidectomy should not be performed unless a distinct indication exists (nasal obstruction, chronic adenoiditis); repeat surgery consists of adenoidectomy plus myringotomy with or without tube insertion. Tonsillectomy alone or myringotomy alone should not be used to treat OME. The subcommittee made negative recommendations that 1) population-based screening programs for OME not be performed in healthy, asymptomatic children, and 2) because antihistamines and decongestants are ineffective for OME, they should not be used for treatment; antimicrobials and corticosteroids do not have long-term efficacy and should not be used for routine management. The subcommittee gave as options that 1) tympanometry can be used to confirm the diagnosis of OME and 2) when children with OME are referred by the primary clinician for evaluation by an otolaryngologist, audiologist, or speech-language pathologist, the referring clinician should document the effusion duration and specific reason for referral (evaluation, surgery) and provide additional relevant information such as history of acute otitis media and developmental status of the child. The subcommittee made no recommendations for 1) complementary and alternative medicine as a treatment for OME, based on a lack of scientific evidence documenting efficacy, or 2) allergy management as a treatment for OME, based on insufficient evidence of therapeutic efficacy or a causal relationship between allergy and OME. Last, the panel compiled a list of research needs based on limitations of the evidence reviewed. The purpose of this guideline is to inform clinicians of evidence-based methods to identify, monitor, and manage OME in children aged 2 months through 12 years. The guideline may not apply to children more than 12 years old, because OME is uncommon and the natural history is likely to differ from younger children who experience rapid developmental change. The target population includes children with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The guideline is intended for use by providers of health care to children, including primary care and specialist physicians, nurses and nurse practitioners, physician assistants, audiologists, speech-language pathologists, and child-development specialists. The guideline is applicable to any setting in which children with OME would be identified, monitored, or managed. This guideline is not intended as a sole source of guidance in evaluating children with OME. Rather, it is designed to assist primary care and other clinicians by providing an evidence-based framework for decision-making strategies. It is not intended to replace clinical judgment or establish a protocol for all children with this condition and may not provide the only appropriate approach to diagnosing and managing this problem.

Otitis media with effusion (OME) is amongst the most common pediatric diseases and the most common cause of hearing loss in children. It is accepted that adenoid hypertrophy (AH) is related to OME incidence. Better understanding of the correlation between the relative size of AH and the incidence of persistent OME may provide evidence to support a more standardized approach to the diagnosis and treatment of OME. A retrospective study carried out between April 2016 and April 2018 collected data on 65 children aged 2-12 years, diagnosed with chronic OME and symptoms of AH, where conservative therapy failed. Pre-diagnostic data were collected from patient history, otoscopy, rhinoscopy, and oropharyngoscopy findings. Diagnostic workup included tympanometry, audiometry, and flexible nasal fiberoptic endoscopy. Adenoid grading was performed according to Cassano method after endoscopic visualization. Of the 65 patients, 37 were male and 28 were female. There was no statistically significant difference according to gender or average age. The highest incidence of persistent OME with AH was recorded in the youngest age groups (2-5 and 6-9 years). The most frequent AH grades were grade II (35.38%) and grade III (50.77%), yielding a statistically significant result. The most common presenting symptoms were hearing impairment, snoring, and nasal obstruction (100%, 64.62% and 60%, respectively). Higher AH grades are critical for persistence of OME and may cause conservative therapy failure.

This plain language summary serves as an overview in explaining otitis media with effusion (pronounced Oh-TIE-tis ME-dee-uh with Ef-YOO-zhun), abbreviated "OME" and often called "ear fluid." The summary applies to children aged 2 months through 12 years with OME and is based on the 2015 "Clinical Practice Guideline: Otitis Media with Effusion (Update)." The evidence-based guideline includes research to support more effective diagnosis and treatment of OME in children. The guideline was developed as a quality improvement opportunity for managing OME by creating clear recommendations to use in medical practice.

The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry. The use of tympanometric gradient in addition to static admittance is the focus of this study. The authors enrolled 146 female and 129 male patients. The participants were allocated into groups as follow: Group A1 consisted of 50 healthy children. Group A2 consisted of 86 children with otitis media with effusion. Group B1 consisted of 85 healthy adults. Group B2 consisted of 54 adults with otitis media with effusion. All diagnostic otoscopic examination and tympanometry were performed in both ears. The authors analyzed the distribution of tympanograms in patients with otitis media with effusion and healthy controls. When the right and left ear canal volume of either children or adults with otitis media with effusion compared with healthy controls, no statistically significant different was observed (P > 0.05). On the other hand, the statistically significant difference was detected for the values of compliance, pressure and gradient of either children or adults with otitis media with effusion compared with healthy controls (P < 0.05). The authors found the values range from 0.01 to 1.52 mL gradients (mean least value 0.15 mL) in adults and the values range from 0.01 to 0.93 mL gradients (mean least value 0.10 mL) in children in the presence of otitis media with effusion. The authors think that tympanometric gradient may be useful to detect the otitis media with effusion.

To explore the value of otoscopy in diagnosing OME when performed by otorhinolaryngology, pediatrics, and primary care physicians; to evaluate the interobserver and intraobserver agreement of interpretation of otoscopy images. A cross-sectional study using an anonymous mailed survey was used. We presented pre-recorded otoscopy images of pediatric patients to otorhinolaryngology, pediatrics, and primary care physicians (ten volunteer specialists and residents from each medical specialty). All participants had to answer "yes" or "no" if they considered that the image corresponded or not to an OME case, respectively. We considered that the images were positive for OME whenever the respective tympanogram was type B. Thirty-one otoscopy images and 1860 responses provided by sixty physicians were analyzed. The accuracy of otoscopy in diagnosing OME was highest in the Otolaryngologists group (mean 74.8%), with the worst rate observed in the primary care residents group (mean 51.3%). Overall sensitivity, specificity, and positive predictive value of otoscopy for diagnosing OME were significantly higher when performed by otorhinolaryngologists (75.8%, 72.8%, 66.8%, respectively). Fleiss' kappa showed that interobserver agreement was globally weak within each group of specialties, with overall better interobserver agreement observed among otorhinolaryngologists (κ = 0.30; 95% CI 0.27-0.32). According to our data, simple otoscopy as a single diagnostic method in pediatric OME is insufficient, even for otorhinolaryngologists. Current recommendations must be followed to improve diagnostic accuracy.

A flat tympanogram predicts a middle ear effusion in about 90% of cases. This paper describes how to perform tympanometry, some common problems when doing it and how to classify the curves in normal (type A), middle ear effusion (type B) or negative pressure (type C). The theoretical background of impedance audiometry is outlined. The stapedius reflex, pneumatic otoscopy, reflexometry and otomicroscopy are described as supplements or alternatives in diagnosing fluid in the middle ear. Tympanometry is recommended as a diagnostic modality for general practitioners.

The clinical practice guideline on otitis media with effusion (OME) provides evidence-based recommendations on diagnosing and managing OME in children. This is an update of the 1994 clinical practice guideline "Otitis Media With Effusion in Young Children," which was developed by the Agency for Healthcare Policy and Research (now the Agency for Healthcare Research and Quality). In contrast to the earlier guideline, which was limited to children aged 1 to 3 years with no craniofacial or neurologic abnormalities or sensory deficits, the updated guideline applies to children aged 2 months through 12 years with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The American Academy of Pediatrics, American Academy of Family Physicians, and American Academy of Otolaryngology-Head and Neck Surgery selected a subcommittee composed of experts in the fields of primary care, otolaryngology, infectious diseases, epidemiology, hearing, speech and language, and advanced practice nursing to revise the OME guideline. The subcommittee made a strong recommendation that clinicians use pneumatic otoscopy as the primary diagnostic method and distinguish OME from acute otitis media (AOM). The subcommittee made recommendations that clinicians should (1) document the laterality, duration of effusion, and presence and severity of associated symptoms at each assessment of the child with OME; (2) distinguish the child with OME who is at risk for speech, language, or learning problems from other children with OME and more promptly evaluate hearing, speech, language, and need for intervention in children at risk; and (3) manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known), or from the date of diagnosis (if onset is unknown). The subcommittee also made recommendations that (4) hearing testing be conducted when OME persists for 3 months or longer, or at any time that language delay, learning problems, or a significant hearing loss is suspected in a child with OME; (5) children with persistent OME who are not at risk should be reexamined at 3- to 6-month intervals until the effusion is no longer present, significant hearing loss is identified, or structural abnormalities of the eardrum or middle ear are suspected; and (6) when a child becomes a surgical candidate, tympanostomy tube insertion is the preferred initial procedure. Adenoidectomy should not be performed unless a distinct indication exists (nasal obstruction, chronic adenoiditis); repeat surgery consists of adenoidectomy plus myringotomy, with or without tube insertion. Tonsillectomy alone or myringotomy alone should not be used to treat OME. The subcommittee made negative recommendations that (1) population-based screening programs for OME not be performed in healthy, asymptomatic children and (2) antihistamines and decongestants are ineffective for OME and should not be used for treatment; antimicrobials and corticosteroids do not have long-term efficacy and should not be used for routine management. The subcommittee gave as options that (1) tympanometry can be used to confirm the diagnosis of OME and (2) when children with OME are referred by the primary clinician for evaluation by an otolaryngologist, audiologist, or speech-language pathologist, the referring clinician should document the effusion duration and specific reason for referral (evaluation, surgery), and provide additional relevant information such as history of AOM and developmental status of the child. The subcommittee made no recommendations for (1) complementary and alternative medicine as a treatment for OME based on a lack of scientific evidence documenting efficacy and (2) allergy management as a treatment for OME based on insufficient evidence of therapeutic efficacy or a causal relationship between allergy and OME. Last, the panel compiled a list of research needs based on limitations of the evidence reviewed. The purpose of this guideline is to inform clinicians of evidence-based methods to identify methods to identify, monitor, and manage OME in children aged 2 months through 12 years. The guideline may not apply to children older than 12 years because OME is uncommon and the natural history is likely to differ from younger children who experience rapid developmental change. The target population includes children with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The guideline is intended for use by providers of health care to children, including primary care and specialist physicians, nurses and nurse practitioners, physician assistants, audiologists, speech-language pathologists, and child development specialists. The guideline is applicable to any setting in which children with OME would be identified, monitored, or managed. This guideline is not intended as a sole source of guidance in evaluating children with OME. Rather, it is designed to assist primary care and other clinicians by providing an evidence-based framework for decision-making strategies. It is not intended to replace clinical judgment or establish a protocol for all children with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

This study aims to investigate the inter-rater reliability and agreement of the diagnosis of otitis media with effusion, acute otitis media, and no effusion cases based on an otoscopy image and in some cases an additional wideband tympanometry measurement of the patient. 1409 cases were examined and diagnosed by an otolaryngologist in the clinic, and otoscopy examination and wideband tympanometry (WBT) measurement were conducted. Afterwards, four otolaryngologists (Ear, Nose, and Throat doctors, ENTs), who did not perform the acute examination of the patients, evaluated the otoscopy images and WBT measurements results for diagnosis (acute otitis media, otitis media with effusion, or no effusion). They also specified their diagnostic certainty for each case, and reported whether they used the image, wideband tympanometry, or both, for diagnosis. All four ENTs agreed on the diagnosis in 57% of the cases, with a pairwise agreement of 74%, and a Light's Kappa of 0.58. There are, however, large differences in agreement and certainty between the three diagnoses. Acute otitis media yields the highest agreement (77% between all four ENTs) and certainty (0.90), while no effusion shows much lower agreement and certainty (34% and 0.58, respectively). There is a positive correlation between certainty and agreement between the ENTs across all cases, and both certainty and agreement increase for cases where a WBT measurement is shown in addition to the otoscopy image. The inter-rater reliability between four ENTs was high when diagnosing acute otitis media and lower when diagnosing otitis media with effusion. However, WBT can add valuable information to get closer to the ground-truth diagnosis without myringotomy. Furthermore, the diagnostic certainty increases when the WBT is examined together with the otoscopy image.

Thirty years of treating secretory otitis media by what is presently considered an alternate approach is discussed. Early experience with using a polyethylene tube in one ear only led to a formal study of the efficacy of polyethylene tube use when combined with adenoidectomy or adenotonsillectomy. This study included 31 children with chronic bilateral secretory otitis media treated by tonsillectomy and adenoidectomy. At the time of surgery, one ear was intubated and the other served as a control with no treatment. Using audiometric criteria, it was found that there was no significant difference between the intubated and control ears after a 6- to 8-week follow-up. Also documented is a series of 425 children suffering from chronic secretory otitis media, all of whom were resistant to prior ear, nose, and throat or pediatric treatment. Fifty-three children had tonsillectomies and adenoidectomies without tube insertion and were followed up for at least 1 year. Audiometry was used to measure the result of therapy that was successful in more than 90% of the patients.

The comparative study presented here evaluated pediatricians from Italy, Greece, South Africa, and a reference group in the USA to determine (i) their ability to accurately diagnose acute otitis media (AOM) and otitis media with effusion (OME) using otoscopy, (ii) their knowledge of antibiotics, and (iii) their technical competence in performing tympanocentesis. The participants included 66 pediatricians from Italy, 115 from Greece, 36 from South Africa and 2,190 from the USA (reference group). Each pediatrician viewed nine video-recorded otoscopic examinations of tympanic membranes, after which their ability to differentiate AOM, OME and normal was ascertained. Questions were posed regarding appropriate, pathogen-directed antibiotic selection for AOM. A mannequin model was used to assess the technical proficiency of each pediatrician in performing tympanocentesis. Results were recorded for each group as the mean percentage +/- standard deviation. The correct diagnosis was made by each group of pediatricians in the following frequencies: Italy, 54+/-27% (range, 18-94%); Greece, 36+/-12% (range, 23-56%); South Africa, 53+/-21% (range, 22-88%); and the USA, 51+/-11% (range, 29-72%). The difference between results from Greece and the US reference group was statistically significant ( P=0.002). Pediatricians from each group over-diagnosed AOM with the following frequencies: Italy, 18+/-19% (range, 2-49%); Greece, 34+/-13% (8-50%); South Africa, 23+/-14% (7-44%); and the US reference group, 26+/-19% (7-51%). Pediatricians correctly selected an antibiotic recommended for treatment of AOM caused by drug-resistant Streptococcus pneumoniae as follows: Italy, 89%; Greece, 77%; South Africa, 82%; and the USA, 80%. For treatment of beta-lactamase-producing Haemophilus influenzae, the results were: Italy, 90%; Greece, 70%; South Africa, 81%; and the USA, 77%. Tympanocentesis was optimally performed by >/=86% of all pediatricians. The results indicate that pediatricians may often misdiagnose OME as AOM, but they select appropriate antibiotics about 80% of the time and can be trained to accurately perform tympanocentesis.

The distinction between acute suppurative otitis media (AOM) and otitis media with effusion (OME) is important for antibiotic treatment decisions. Tympanocentesis may be useful in the diagnosis of AOM in selected patients. To assess physician accuracy in diagnosing AOM and OME from physical examination findings and technical competence in performing tympanocentesis. Five hundred fourteen pediatricians and 188 otolaryngologists viewed 9 different videotaped pneumatic otoscopic examinations of tympanic membranes during a continuing medical education course. Diagnostic differentiation of AOM, OME, and a normal tympanic membrane was ascertained. An infant mannequin model was used to assess the technical proficiency of performing tympanocentesis on artificial tympanic membranes. Overall, the average correct diagnosis by pediatricians was 50% (range, 25%-73%) and by otolaryngologists was 73% (range, 48%-88%). Pediatricians and otolaryngologists correctly recognized the absence of normality 89% to 100% and 93% to 100% of the time, respectively, but overdiagnosed AOM in 7% to 53% (mean, 27%) and in 3% to 23% (mean, 10%) of examinations. Performance of tympanocentesis was optimally performed by 89% of otolaryngologists and by 83% of pediatricians. The use of video-presented examinations to assess diagnostic ability suggests that AOM and OME may be misdiagnosed often. Interactive continuing medical education courses with simulation technology may enhance skills and improve diagnostic accuracy and treatment paradigms.

The American Academy of Otolaryngology-Head and Neck Surgery Foundation has published a supplement to this issue of Otolaryngology-Head and Neck Surgery featuring the updated "Clinical Practice Guideline: Otitis Media with Effusion." To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 18 recommendations developed emphasize diagnostic accuracy, identification of children who are most susceptible to developmental sequelae from otitis media with effusion, and education of clinicians and patients regarding the favorable natural history of most otitis media with effusion and the lack of efficacy for medical therapy (eg, steroids, antihistamines, decongestants). An updated guideline is needed due to new clinical trials, new systematic reviews, and the lack of consumer participation in the initial guideline development group.

Data from cohort studies and untreated groups in randomized controlled trials can be identified through systematic literature review and synthesized with meta-analysis to estimate natural history of acute otitis media (AOM) and otitis media with effusion (OME). Systematic literature review and meta-analysis. Source articles were identified by MEDLINE search through August 2002 plus manual crosschecks of bibliographies and published meta-analyses. Data were abstracted independently by two investigators and combined with random effects meta-analysis to estimate spontaneous resolution, 95% confidence intervals (CI), and heterogeneity. Sensitivity analysis was performed. Sixty-three articles met inclusion criteria. AOM symptoms improved within 24 hours without antibiotics in 61% of children (95% CI, 50-72%), rising to 80% by 2 to 3 days (95% CI, 69-90%). Suppurative complications were comparable if antibiotics were withheld (0.12%) or provided (0.24%). Children entered recurrent AOM trials with a mean rate of 5.5 or more annual episodes but averaged only 2.8 annual episodes while on placebo (95% CI, 2.2-3.4). No AOM episodes occurred in 41%, and only 17% remained otitis prone (3 or more episodes). OME after untreated AOM had 59% resolution by 1 month (95% CI, 50-68%) and 74% resolution by 3 months (95% CI, 68-80%). OME of unknown duration had 28% spontaneous resolution by 3 months (95%, CI 14-41%), rising to 42% by 6 months (95% CI, 35-49%). In contrast, chronic OME had only 26% resolution by 6 months and 33% resolution by 1 year. The natural history of otitis media is very favorable. Combined estimates of spontaneous resolution provide a benchmark against which to judge new or established interventions. The need for surgery in children with recurrent AOM or chronic OME should be balanced against the likelihood of timely spontaneous resolution and the potential risk of learning, language, or other adverse sequelae from persistent middle ear effusion. Further research is needed to identify prognostic factors that can target children unlikely to improve spontaneously for earlier intervention.

Controversy continues over the factors involved in the development of the mastoid air cell system (MACS). This study examines the effect of persistent secretory otitis media with effusion (SOME) on the development of the MACS. Thirty-one children, aged 4, were drawn from a cohort of cleft palate children in a multi-centre, prospective otological study set up in 1984. The initial presence of SOME was assessed by otoscopy, tympanometry and bilateral myringotomy, performed under the same anaesthetic as surgical repair of the cleft lip or palate. Only one ear in each child was ventilated with a tube and the other, the control ear, was assessed by regular follow-up otoscopy and tympanometry. The persistence of SOME after palate repair in over 70% of the non-ventilated ears in 4 years olds and the presence of a contralateral ventilated middle ear provides the perfect model for assessing the effect of SOME on MACS development. Plain, lateral mastoid X-rays were assessed by planimetry to give a well accepted measurement of mastoid pneumatization. Nine children were excluded from analysis as they did not meet the strict criteria of one persistently ventilated middle ear and one with persistent SOME. 22 children (44 ears) were available for analysis, 9 children were tubed at 3 months and 13 were tubed at 12 to 16 months. In 19 of the 22 ears the mastoid air cell system was larger on the tubed side.(ABSTRACT TRUNCATED AT 250 WORDS)

This review studies the potential relationship between the pathogenesis of allergic rhinitis (AR) and otitis media with effusion (OME) in both adults and children, applying the modified Bradford Hill criteria. While AR and OME are distinct conditions, several epidemiological and experimental studies suggest a significant association, primarily through allergic mechanisms such as Th-2 immune responses, Eustachian tube dysfunction, and inflammatory mediators in the middle ear. Given the substantial diversity and, in many instances, the "low quality" of related studies when assessed against the standards of modern evidence-based medicine, employing a structured framework like the modified Bradford Hill criteria is beneficial for investigating and establishing causality. This approach, which allows a wide range of diverse studies to be classified as direct, mechanistic, or parallel evidence, supports the notion that management of the allergic immune response may improve OME outcomes, although the inconsistencies among studies require further research. Despite current guidelines recommending against the use of antiallergic medications, the application of the above criteria suggests that proper diagnosis and treatment of allergic rhinitis should be strongly considered in adults and children with OME.

To analyze the outcomes and safety of pediatric Balloon Dilation of Eustachian Tube (BDET). Retrospective pooled analysis. Records of 219 patients (425 ears) were analyzed. The inclusion criteria included children 17 years old and younger who underwent BDET with or without adjunctive procedures. Patients had a diagnosis of chronic otitis media with effusion (COME) or recurrent acute otitis media (RAOM) refractory to prior surgical treatment. Procedures were performed by a total of seven surgeons at six surgical centers. Pooled analysis was performed on efficacy, complications, BDET failure, and tympanograms. No major complications were reported; however, minor adverse events occurred in 5.9% of patients. BDET had a 1-year failure-free probability of 93.8% (95% CI: 89.7%-96.3%); at 2 years, it was 87.2% (95% CI: 81.9%-91.0%). Tympanograms improved in 83.7% of ears. BDET in pediatric patients demonstrated a favorable safety profile, while being effective and exhibiting long-lasting durability.

Audiometric tests provide information about hearing in otitis media with effusion (OME). Questionnaires can supplement this information by supporting clinical history-taking as well as potentially providing a standardized and comprehensive assessment of the impact of the disease on a child. There are many possible candidate questionnaires. This study aimed to assess the quality and usability of parent / child questionnaires in OME assessment. Fifteen, published questionnaires, commonly used in audiological departments (Auditory Behaviour in Everyday Life (ABEL), Children's Auditory Performance Scale (CHAPS), Children's Home Inventory for Listening Difficulties (CHILD), Children's Outcome Worksheets (COW), Evaluation of Children's Listening and Processing Skills (ECLiPS), Early Listening Function (ELF), Fisher's Auditory Problem Checklist (FAPC), Hearing Loss 7 (HL-7), Listening Inventory for Education- Revised (LIFE-R Student), Listening Inventory for Education UK Individual Hearing Profile (LIFE-UK IHP), LittlEARS Auditory Questionnaire (LittlEARS), Listening Situations Questionnaire (LSQ), Otitis Media 6 (OM-6), Quality of Life in Children's Ear Problems (OMQ-14), Parents' Evaluation of Aural/Oral Performance of Children (PEACH) were assessed according to the following 8 criteria: conceptual clarity, respondent burden, reliability, validity, normative data, item bias, ceiling/ floor effects, and administrative burden. ECLiPS, LittlEARS and PEACH scored highest overall based on the assessment criteria established for this study. None of the questionnaires fully satisfied all 8 criteria. Although all questionnaires assessed issues considered to be of at least adequate relevance to OME, the majority had weaknesses with respect to the assessment of psychometric properties, such as item bias, floor/ceiling effects or measurement reliability and validity. Publications reporting on the evaluation of reliability, validity, normative data, item bias and ceiling/floor effects were not available for most of the questionnaires. This formal evaluation of questionnaires, currently available to clinicians, highlights three questionnaires as potentially offering a useful adjunct in the assessment of OME in clinical or research settings. These were the ECLiPS, which is suitable for children aged 6 years and older, and either the LittlEARS or the PEACH for younger children. The latter two are narrowly focused on hearing, whereas ECLiPS has a broader focus on listening, language and social difficulties.

This update of a 2004 guideline codeveloped by the American Academy of Otolaryngology-Head and Neck Surgery Foundation, the American Academy of Pediatrics, and the American Academy of Family Physicians, provides evidence-based recommendations to manage otitis media with effusion (OME), defined as the presence of fluid in the middle ear without signs or symptoms of acute ear infection. Changes from the prior guideline include consumer advocates added to the update group, evidence from 4 new clinical practice guidelines, 20 new systematic reviews, and 49 randomized control trials, enhanced emphasis on patient education and shared decision making, a new algorithm to clarify action statement relationships, and new and expanded recommendations for the diagnosis and management of OME. The purpose of this multidisciplinary guideline is to identify quality improvement opportunities in managing OME and to create explicit and actionable recommendations to implement these opportunities in clinical practice. Specifically, the goals are to improve diagnostic accuracy, identify children who are most susceptible to developmental sequelae from OME, and educate clinicians and patients regarding the favorable natural history of most OME and the clinical benefits for medical therapy (eg, steroids, antihistamines, decongestants). Additional goals relate to OME surveillance, hearing and language evaluation, and management of OME detected by newborn screening. The target patient for the guideline is a child aged 2 months through 12 years with OME, with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The guideline is intended for all clinicians who are likely to diagnose and manage children with OME, and it applies to any setting in which OME would be identified, monitored, or managed. This guideline, however, does not apply to patients <2 months or >12 years old. The update group made strong recommendations that clinicians (1) should document the presence of middle ear effusion with pneumatic otoscopy when diagnosing OME in a child; (2) should perform pneumatic otoscopy to assess for OME in a child with otalgia, hearing loss, or both; (3) should obtain tympanometry in children with suspected OME for whom the diagnosis is uncertain after performing (or attempting) pneumatic otoscopy; (4) should manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known) or 3 months from the date of diagnosis (if onset is unknown); (5) should recommend against using intranasal or systemic steroids for treating OME; (6) should recommend against using systemic antibiotics for treating OME; and (7) should recommend against using antihistamines, decongestants, or both for treating OME.The update group made recommendations that clinicians (1) should document in the medical record counseling of parents of infants with OME who fail a newborn screening regarding the importance of follow-up to ensure that hearing is normal when OME resolves and to exclude an underlying sensorineural hearing loss; (2) should determine if a child with OME is at increased risk for speech, language, or learning problems from middle ear effusion because of baseline sensory, physical, cognitive, or behavioral factors; (3) should evaluate at-risk children for OME at the time of diagnosis of an at-risk condition and at 12 to 18 months of age (if diagnosed as being at risk prior to this time); (4) should not routinely screen children for OME who are not at risk and do not have symptoms that may be attributable to OME, such as hearing difficulties, balance (vestibular) problems, poor school performance, behavioral problems, or ear discomfort; (5) should educate children with OME and their families regarding the natural history of OME, need for follow-up, and the possible sequelae; (6) should obtain an age-appropriate hearing test if OME persists for 3 months or longer OR for OME of any duration in an at-risk child; (7) should counsel families of children with bilateral OME and documented hearing loss about the potential impact on speech and language development; (8) should reevaluate, at 3- to 6-month intervals, children with chronic OME until the effusion is no longer present, significant hearing loss is identified, or structural abnormalities of the eardrum or middle ear are suspected; (9) should recommend tympanostomy tubes when surgery is performed for OME in a child <4 years old; adenoidectomy should not be performed unless a distinct indication exists (nasal obstruction, chronic adenoiditis); (10) should recommend tympanostomy tubes, adenoidectomy, or both when surgery is performed for OME in a child ≥4 years old; and (11) should document resolution of OME, improved hearing, or improved quality of life when managing a child with OME.

We report the findings of an evidence assessment on the accuracy of methods of diagnosing middle ear effusion in children with otitis media with effusion (OME). We searched Medline (1966-January 2000), the Cochrane Library (through January 2000), and Embase (1980-January 2000) and identified additional articles from reference lists in proceedings, published articles, reports, and guidelines. Excluded were nonhuman studies; case reports; editorials; letters; reviews; practice guidelines; non-English-language publications; and studies on patients with immunodeficiencies, craniofacial anomalies (including cleft palate), primary mucosal disorders, or genetic conditions. From each eligible study, we calculated the sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and prevalence of OME in the cohort. We determined the number of studies for each comparison of a diagnostic method and a reference standard listed within the scope of our assessment. For comparisons with 3 or more studies, we derived random effects estimates of sensitivity, specificity, and prevalence rate. Using the pooled estimates, we plotted the performance of each diagnostic test in terms of sensitivity and (1 - specificity) and identified the best performer among the tests included in the comparison. Among 8 diagnostic methods, pneumatic otoscopy had the best apparent performance with a sensitivity of 94% (95% confidence interval: 92%-96%) and a specificity of 80% (95% confidence interval: 75%-86%). However, examiner qualifications were reported inconsistently, and training was not specified. The finding that pneumatic otoscopy can do as well as or better than tympanometry and acoustic reflectometry has significant practical implications. For the typical clinician, pneumatic otoscopy should be easier to use than other diagnostic methods. The important question may be what degree of training will be needed for the clinician to be as effective with pneumatic otoscopy as were the examiners in the studies reviewed in this report.

Acute otitis media (AOM) and otitis media with effusion (OME) rely on accurate characterization of middle ear effusion (MEE). Optical coherence tomography (OCT) is a potential modality for noninvasive analysis of MEE, thereby assisting with otitis media diagnosis. This study aims to compare the diagnostic performance of OCT with otoscopy and tympanometry in pediatric patients. A prospective convenience sample of 164 pediatric patients aged 6 months to 12 years was recruited from two tertiary care pediatric otolaryngology clinics. During their visit, each child underwent otoscopy, tympanometry, and OCT evaluation. Scans were reviewed by both a fellowship-trained pediatric otolaryngologist and an individual with limited medical background. Pairwise comparisons between tests were performed to assess percent agreement, sensitivity, and specificity of OCT in the identification of MEE. A total of 164 pediatric patients (328 ears) were enrolled, with 32% of ears classified as having a middle ear effusion by otoscopy, 24% by tympanometry, and 18% by OCT. Across all age groups, otoscopy and tympanometry agreed 81.2% of the time, otoscopy and OCT 77.7% of the time, and tympanometry and OCT 80.5% of the time. Cohen's Kappa showed moderate agreement between clinical and non-clinical OCT raters (κ = 0.41). Analysis revealed a sensitivity of 74% and specificity of 93% for OCT, comparable to existing methods. Optical coherence tomography demonstrates promise as a valuable tool for MEE assessment in pediatric patients, with performance comparable to pneumatic otoscopy and tympanometry. These findings emphasize its potential for enhancing diagnostic accuracy and disease progression monitoring in clinical practice.

More than 20 years ago, a shrewd clinician remarked, "There is little evidence that those antimicrobial agents which hypothetically or in vitro are more effective ... are superior in the treatment of otitis when compared to penicillin alone." Several hundred clinical trials later, the advantages of broad spectrum drugs remain unproved, and questions remains as to whether antibiotics are required for most episodes of AOM. Further, antibiotics have been demoted to the status of optional therapy for OME. This situation is unlikely to change as new studies with new antibiotics proliferate. What is clear, however, is that accelerated patterns of bacterial resistance mandate an evidence-based approach to managing otitis media. Bacteria have an uncanny ability to learn new mechanisms of antibiotic resistance. A large part of bacterial "education" has undoubtedly been fueled by antibiotic prescriptions from well-intentioned physicians, with unrealistic expectations of drug efficacy. A judicious approach to antibiotic treatment of otitis media can result only from knowing the spontaneous course of the disorder and incremental effect of antibiotics on clinical outcomes. In this article, a series of unifying concepts are developed to help practicing clinicians with an evidence-based approach to managing otitis media. Critical review of the published evidence suggests that the most favorable outcomes from medical treatment will occur if practitioners: appreciate the favorable natural history of untreated otitis media realize that OME may take months to resolve following a single AOM episode modify risk factors to improve the odds of spontaneous resolution use pneumatic otoscopy and confirmatory tympanometry to diagnose OME recognize the limited impact of antibiotic therapy on treatment and prevention balance the benefits of antibiotics against the risk of accelerated bacterial resistance avoid repetitive, prolonged, or prophylactic antibiotic treatment of chronic OME avoid ineffective therapy, such as antihistamine/decongestant preparations An important aspect of management is helping caregivers understand the natural history of otitis media and the impact of medical treatment on shortterm and long-term outcomes. Realistic expectations on the part of all involved parties should facilitate rational decisions about watchful waiting, medical therapy, and the need for surgical intervention.

Otitis media with effusion (OME) is an important clinical entity because of its high prevalence, difficulties in diagnosis, complications and diversities in management. Herein, we aimed to evaluate current physician approaches on OME and determine clinical adherence to current guidelines. A total of 370 physicians [Group 1: pediatricians (n = 256, 69.2%), Group 2: otorhinolarynologists (n = 114, 30.8%)] completed a survey instrument addressing demographic data and clinical practice parameters on OME in children. We also compared clinical approaches of Group 1 and Group 2. In addition, multiple logistic regression analysis was performed to evaluate factors which may effect correct approaches. The mean period of clinical experience was 9.30 ± 8.35 [median 6 (1-40)] years. A total of 311 (84%) respondents reported satisfactory level of self-confidence as regards of clinical approaches to OME. Reduced mobility of the tympanic membrane and preference of pneumatic otoscopy was signified by 107 (28.9%) and 64 (17.3%) respondents, respectively. Fifty-six (15.1%) physicians identified "watchful waiting" for 3 months for children who are not at risk while 314 (84.9%) reported preference of medications, with antibiotics the most preferred prescription (n = 223, 63%). Comparison of Group 1 and Group 2 indicated similar results except better, yet insufficient, characterization of physical examination findings of OME by Group 2 (p < 0.001, for each parameter). Group 2 preferred tympanometry more in uncertain cases (p < 0.001) and handled chronic cases better (p < 0.001). Multiple logistic regression analysis revealed lower signification of reduced mobility of the tympanic membrane for respondents who denoted depending on personal experience ([OR] = 3.077 [95% CI 1.042-9.09]) or following clinical guidelines ([OR] = 3.365 [95% CI 1.38-8.20]) rather than combining them both. Rate of antibiotic avoidance was lowest in physicians with a period of clinical experience<5 years ([OR] = 2.14 [95% CI 1.32-3.48]). Despite notifying high self-confidence and adherence to current guidelines on OME, both pediatricians and otorhinolaryngologists lacked to exhibit proper approaches. Further research is warranted to evaluate the causes of poor adherence to current guidelines and bring suggestions for the maintenance of consistent and correct clinical approaches to OME.

Otitis media with effusion (OME) is a leading cause of acquired hearing loss in children worldwide. However, previous South African studies have consistently reported the local paediatric OME prevalence to be lower than typically published in international literature. Furthermore, no South African studies have investigated OME in children with adenotonsillar hypertrophy. The objective of this study was to determine the prevalence of OME in children admitted for adeno-tonsillectomy at our institution in Pretoria, South Africa. In addition, the study sought to gauge the impact of OME on quality of life using a validated questionnaire (OM-6). A cross-sectional, observational study was conducted between July 2015 and May 2016 at the Otorhinolaryngology outpatient department at DGMAH. he study included 109 consecutively sampled children, aged 2-12 years (mean 6.1; 49.7% female). Pneumatic otoscopy and tympanometry were performed on all participants. Adenoid hypertrophy was quantified using he adenoid-nasopharyngeal ratio (ANR) on a lateral post-nasal space radiograph (Fujioka's method). The OM-6 questionnaire was completed for each participant. Pure tone audiometry was performed for participants diagnosed with OME. The prevalence of bilateral OME was 11.9%. For unilateral OME, the prevalence was 22.9% and 16.5%, for the left and right ears, respectively (p > 0.05). The mean hearing loss (SD) was 19.8 dB (9.4). Clinically significant adenoid hypertrophy (ANR ≥ 0.71) was present in 43% of participants. There was no statistically significant (p > 0.05) correlation between the presence OME and adenoid hypertrophy. The mean total OM-6 survey score was 1.67 (SD ± 0.59) in children with OME, and 1.31 (SD ± 0.45) without OME, showing no statistically significant difference (p > 0.05). There was a significant (P < 0.05) correlation between OME and the presence of atopy. Adeno-tonsillar pathology may play an aetio-pathological role in the development of OME. However, this may be due to the presence of biofilms rather than obstructive adenoid hypertrophy, given the lack of a significant (p > 0.05) correlation between adenoid hypertrophy and OME. Whilst OME was not found to impair quality of life in this population group, the validity of the OM-6 in the South African paediatric population requires further investigation.

Previous studies in humans have indicated that functional obstruction of the eustachian tube (ET) is an important factor in the pathogenesis of otitis media with effusion (OME). This type of obstruction appears to be related to the structural properties of the tube, or to an inefficient active tubal opening mechanism, or both. In this study, functional ET obstruction was created in 22 rhesus monkeys (Macaca mulatta) by surgically altering the tensor veli palatini (TVP) muscle using three different procedures: 1) complete excision of the muscle; 2) transection of the superficial muscle bundle; or 3) transposition of the muscle tendon medial to the hamular process. Prior to surgery, weekly tympanometry, pneumatic otoscopy, and otomicroscpic examinations were performed for a period of at least six months to document middle ear (ME) status. A minimum of four ET function tests were performed on each animal using the inflation-deflation and forced-response tests. Following surgery, these tests and examinations were continued for periods of up to one year. Postoperatively, the animals in which the TVP had been excised developed a sterile ME effusion which proved to be a chronic condition which persisted throughout the follow-up period. Eustachian tube function tests showed a complete absence of any active tubal dilation by swallowing. Animals that had the muscle transected developed abnormal ME pressures , or effusions, or both, which returned to normal in some ears, but which were recurrent or chronic in others. Eustachian tube function tests in these animals showed an initial loss of active tubal function which gradually improved, but not to normal levels, presumably as a result of healing of the muscle. In cases in which the muscle was transposed the ME pathology and ET dysfunction were similar after the surgery, but improved within a short period of time. These data suggest that alteration of the TVP muscle can create functional obstruction of the ET. The severity of ET obstruction depends upon the surgical procedure undertaken. The results of postoperative ET function tests were similar to those recorded from children with recurrent and chronic OME.

In this prospective follow-up investigation, we examined the efficacy of a modified Politzer device in the home treatment of persistent middle ear effusion (MEE) and associated hearing loss in children who had previously participated in a similar clinical trial. Our study group was made up of 38 patients who had been either (1) untreated control participants in the previous study whose hearing in one or both ears had not returned to normal within 11 weeks of their initial audiologic pretest ("former control group"; n = 30), or (2) active-treatment participants in the previous study whose hearing sensitivity in at least one ear had not improved to within normal limits after treatment and who elected to undergo a continuation of treatment ("extended-treatment group"; n = 8). Treatment efficacy was determined by comparing differences in pre- and posttreatment air-conduction thresholds and otoscopic findings. Following treatment, the former control group experienced significant improvements in hearing sensitivity at all frequencies; at the posttreatment test, hearing sensitivity was within normal limits in 43 of 60 ears (71.7%), and normal or moderate tympanic membrane mobility was observed in 30 of 34 otoscopically examined ears (88.2%). In the extended-treatment group, hearing sensitivity returned to within normal limits in 9 of 10 impaired ears (90.0%). These findings further substantiate the efficacy of our modified Politzer device in improving middle ear function and hearing sensitivity in children with MEE, and they support the reliability of the findings reported in our previous study. These results also indicate that many patients in whom initial treatment is not successful may benefit from extended treatment.

The specific aims of the research are to determine whether newborn ears with persistent middle ear effusion at age 30 to 48 hours are more likely to develop chronic otitis media with effusion over the first year of life when compared with ears without persistent middle ear effusion. The hypothesis is that neonates with middle ear effusion persisting to 30 to 48 hours are more likely to develop chronic otitis media with effusion. Prospective, case-control design. Loupe-magnified pneumatic otoscopy performed at the time of newborn hearing screening determined presence or absence of effusion. Infants enrolled in the study returned for outpatient examinations. University medical center well-baby nursery and out-patient audiology clinic. From 454 neonates, 14 experimental subjects with neonatal middle ear effusions and 15 control subjects free of neonatal effusion were recruited for the study and followed-up for 1 year. Outpatient study tests included transient-evoked otoacoustic emissions, tympanometry, pneumatic otoscopy, and visual reinforcement audiometry (starting at age 6 months), at 3, 6, 9, and 12 months of age. Experimental (neonatal effusion) infants were followed-up starting at age 1 month. Infants found at any follow-up examination to have effusion on otoscopy were followed-up and tested 1 month later. Chronic otitis media with effusion defined as hypomobile or immobile tympanic membrane on pneumatic otoscopy in one or both ears for three consecutive monthly examinations. Hearing loss defined as greater than 25-dB hearing loss visual reinforcement audiometry thresholds. Eight experimental infants (58%) and three control infants (20%) developed chronic otitis media with effusion (p < 0.04). The average number of effusions was 1.27 for control and 4.14 for experimental infants (average number of effusions for each group at 3-, 6-, 9-, and 12-month visits). Warbled tone and speech visual reinforcement audiometry thresholds averaged 3 dB worse in the experimental group, but these differences were not statistically significant. For the control group, mean visual reinforcement audiometry thresholds never exceeded 25 dB hearing loss. For the experimental group, mean visual reinforcement audiometry thresholds exceeded 25 dB hearing loss at 1,000, 2,000, and 4,000 Hz at 9 months. A majority of infants with persistent neonatal middle ear effusion found by pneumatic otoscopy at 30 to 48 hours will develop chronic otitis media with effusion during the first year of life. However, chronic otitis media with effusion is common in all infants (20% of controls), a time during which infants are examined and tested frequently.

Otitis media with effusion (OME) is a pathologic condition of the middle ear that leads to a mild to moderate conductive hearing loss as a result of fluid in the middle ear. Recurring OME in children during the first few years of life has been shown to be associated with poor detection and recognition of sounds in noisy environments, hypothesized to result due to altered sound localization cues. To explore this hypothesis, we simulated a middle ear effusion by filling the middle ear space of chinchillas with different viscosities and volumes of silicone oil to simulate varying degrees of OME. While the effects of middle ear effusions on the interaural level difference (ILD) cue to location are known, little is known about whether and how middle ear effusions affect interaural time differences (ITDs). Cochlear microphonic amplitudes and phases were measured in response to sounds delivered from several locations in azimuth before and after filling the middle ear with fluid. Significant attenuations (20-40 dB) of sound were observed when the middle ear was filled with at least 1.0 ml of fluid with a viscosity of 3.5 Poise (P) or greater. As expected, ILDs were altered by ~30 dB. Additionally, ITDs were shifted by ~600 μs for low frequency stimuli (<4 kHz) due to a delay in the transmission of sound to the inner ear. The data show that in an experimental model of OME, ILDs and ITDs are shifted in the spatial direction of the ear without the experimental effusion.

The characteristics of otoacoustic emissions that make them ideally suited for universal newborn hearing loss screening could potentially be useful for the screening of older children. This study was performed in order to assess the role of otoacoustic emissions in a screening programme for middle-ear disorders and hearing loss in school-age children. Cross-sectional, preliminary screening study. Primary schools of Argolida municipality, south-east Greece, between December 2004 and March 2005. PATIENT SELECTION AND RECRUITMENT: All the primary school students of Argolida were invited, by press releases and individually by their teachers, to attend a session of otological and audiological screening. One hundred and ninety-six children were evaluated using transient evoked otoacoustic emissions. Twenty per cent failed in both ears, while in 32 per cent otoacoustic emissions could not be produced in at least one ear. Younger children had higher rates of absent transient evoked otoacoustic emissions. The absence of otoacoustic emissions was highly correlated with tympanic membrane changes seen on otoscopy and the presence of a type B tympanogram. As a single screening modality, otoacoustic emissions had a 100 per cent sensitivity in diagnosing hearing loss worse than 30 dB, and a 90 per cent sensitivity and 64 per cent specificity in diagnosing hearing loss worse than 25 dB, which did not improve by adding tympanometry to the screening protocol. These results strongly suggest the potential usefulness of otoacoustic emission testing in screening school-age children for hearing loss. Further studies, taking into account cost-effectiveness issues, are indicated.

Otitis media with effusion (OME) occurs when fluid collects in the middle-ear space behind the tympanic membrane (TM). As a result of this effusion, sounds can become attenuated by as much as 30-40 dB, causing a conductive hearing loss (CHL). However, the exact mechanical cause of the hearing loss remains unclear. Possible causes can include altered compliance of the TM, inefficient movement of the ossicular chain, decreased compliance of the oval window-stapes footplate complex, or altered input to the oval and round window due to conduction of sound energy through middle-ear fluid. Here, we studied the contribution of TM motion and umbo velocity to a CHL caused by middle-ear effusion. Using the chinchilla as an animal model, umbo velocity (V U) and cochlear microphonic (CM) responses were measured simultaneously using sinusoidal tone pip stimuli (125 Hz-12 kHz) before and after filling the middle ear with different volumes (0.5-2.0 mL) of silicone oil (viscosity, 3.5 Poise). Concurrent increases in CM thresholds and decreases in umbo velocity were noted after the middle ear was filled with 1.0 mL or more of fluid. Across animals, completely filling the middle ear with fluid caused 20-40-dB increases in CM thresholds and 15-35-dB attenuations in umbo velocity. Clinic-standard 226-Hz tympanometry was insensitive to fluid-associated changes in CM thresholds until virtually the entire middle-ear cavity had been filled (approximately >1.5 mL). The changes in umbo velocity, CM thresholds, and tympanometry due to experimentally induced OME suggest CHL arises primarily as a result of impaired TM mobility and TM-coupled umbo motion plus additional mechanisms within the middle ear.

Otitis media with effusion is a highly concurrent disease in young children with adenoid hypertrophy. The aim of this study was to assess the middle ear effusion and audiological characteristics in children with adenoid hypertrophy and compare the various assessment methods. Two hundred and seven candidates who were to undergo adenoidectomy were analyzed using otoscopy, tympanometry, air-conduction auditory steady-state responses (AC-ASSR), and computerized tomography (CT) before adenoidectomy. About 73.4% (304/414) of ears were confirmed to have middle ear effusion (MEE) by otoscopy; 75.4% (312/414) of ears revealed MEE by CT. CT scan correctly predicted all the myringotomy results, giving 100% accuracy on the diagnosis of MEE. Additionally, CT revealed two children with inner ear malformations. Type B tracing tympanogram provided a sensitivity of 91.7% and a specificity of 92.2%. Type C tympanogram with peak pressure < -200 daPa indicated effusion; type C tympanogram having acoustic stapedius reflex could exclude MEE. We excluded the AC-ASSR results of the 4 ears with malformation; 54.4% (223/410) of ears were confirmed of hearing loss. Furthermore, 5.2% (16/310) of the ears with MEE suffered from severe to profound hearing loss. The average threshold level in the 0.25 kHz frequency of children was found to have poorer hearing thresholds than those in the 0.5, 1, 2, and 4 kHz (P < 0.001) frequencies; 29.7% (92/310) of ears with MEE were regarded as normal hearing level. About 55.8% (173/310) of ears with MEE were classified as having slight-mild hearing loss. The practitioners should pay much attention to the middle ear condition and be aware of a possible development of severe to profound hearing loss during the course of MEE in young children with adenoid hypertrophy. CT scan is good for the assessment of MEE before ventilation tube insertion.

This study sought to determine whether SARS-CoV-2 is present in the middle ear fluid (MEF) of patients with COVID-19 who have otitis media with effusion (OME). A case-control study was designed to detect SARS-CoV-2 and six other common respiratory viruses (influenza A virus, influenza B virus, respiratory syncytial virus, adenovirus, human rhinovirus [HRV], and mycoplasma pneumonia) by polymerase chain reaction (PCR) in the MEF of patients with OME. Follow-up tests, including pure-tone audiometry and tympanometry, were conducted. In the COVID-19 group, 18 of 27 MEF specimens were PCR-positive for SARS-CoV-2, with cycle thresholds ranging from 24.9-42.2. And one patient tested positive for the HRV. In the control group, all 15 MEF specimens were PCR-negative for SARS-CoV-2, but two patients tested positive for the HRV. After treatment for OME, 11 patients (40.7%) reported complete resolution, 14 (51.9%) reported improvement, and two (7.4%) reported no change. The average improvement in hearing was 14.5 ± 8.1 dB, and the average air-bone gap decrease was 13.5 ± 9.0 dB. This study confirmed the presence of SARS-CoV-2 in the MEF of patients who were previously COVID-19-positive suggesting a possible association between COVID-19 and OME. OME should be considered a possible symptom of COVID-19.

To investigate the age effects of cleft palate repair on middle ear function and hearing level in patients who underwent cleft palate repair at different ages by audiologic examination. Medical histories were gathered in detail, and audiologic tests (ie, tympanometry and pure tone hearing threshold) were conducted in 126 patients after palatoplasty. The patients were divided into the following 4 groups according to their ages when they underwent cleft palate repair: group I (0-3 years, 73 patients), group II (4-7 years, 29 patients), group III (8-11 years, 16 patients), and group IV (12 years and older, 8 patients). The data regarding tympanograms, hearing levels, and the average hearing thresholds of each group were analyzed using chi-square tests. The prevalence of middle ear dysfunction and hearing loss in the patients who underwent palatoplasty before 3 years old (27.4% and 2.0% respectively) was significantly lower than that in patients who underwent palatopalsty at 12 years or older (75.0% and 43.7%, respectively). Linear-by-linear association revealed that the prevalences of middle ear dysfunction and hearing loss among the 4 groups were significantly different ( P < .05). The prevalence of middle ear dysfunction and hearing loss tended to increase with advancing age at the time of cleft palate repair. From an audiologist's perspective, palatoplasty at an early age is very beneficial in helping children with cleft palates acquire better middle ear function and hearing level.

This study sought to establish the value of tympanometry and otoscopy for predicting significant conductive hearing loss in remote-area Aboriginal children, and also to measure the range of hearing loss which can be expected with middle ear disease, with or without a tympanic membrane (TM) perforation. A field study is reported of 255 Aboriginal children aged up to 16 years who were examined with pneumotoscopy and tympanometry and whose hearing was tested under controlled acoustic conditions. Results showed that pneumatic otoscopy for detection of middle ear effusion and identification of perforations resulted in the best rate of prediction of significant conductive hearing loss. Furthermore, the hearing of children with perforated TMs (mean pure-tone average 30.0 dB; S.D. 11.1) was significantly worse than those in which tympanometry suggested middle ear effusion (mean pure-tone average 20.3 dB; S.D. 9.6), and both differed significantly from ears showing normal tympanograms (mean pure-tone average 11.2 dB; S.D. 5.9). Implications for community-based hearing screening and classroom management of affected children are discussed.

Otitis media (OM) has been observed at elevated prevalence rates in Greenlandic children. OM associated hearing loss (HL) may compromise the children's linguistic skills, social development and educational achievements. We investigated the prevalence of chronic suppurative otitis media (CSOM), otitis media with effusion (OME) and tympanic membrane sequelae of OM, and compared the corresponding hearing thresholds. In 2010 we examined a cohort of 223 Greenlandic children aged 4-10 years by video otoscopy, tympanometry and tested hearing thresholds for the low-frequencies: 500, 1000 and 2000Hz and the high-frequencies: 4000 and 6000Hz. HL was categorized according to the worst hearing ear and was compared within the groups: CSOM, OME, tympanic membrane sequelae of OM and normal. Of 207 children, 5.8% had CSOM, 13.9% had OME and 55.6% had tympanic membrane sequelae of OM. The median pure tone average in low-frequencies/high-frequencies were: CSOM: 34.2/31.3dB, OME: 23.3/22.5dB, Sequelae of OM: 13.3/15dB and normal ears: 11.7/12.5dB. We found a significant difference (p<0.05) between the four groups. In 56.5% of all children a HL>15dB in any frequency was found, while 6.5% suffered from a bilateral low-frequency HL>25dB. The severity of OM significantly corresponded to increased HL. The burden of CSOM and HL remains high in young Greenlandic children. Aggressive treatment with antibiotics, improved hearing rehabilitation, sound field amplification in classrooms and otosurgical capacity should be further promoted in Greenland.

To study longitudinal prevalence of otitis media with effusion (OME) in children between 7 and 16 years of age by cleft group, and hearing sensitivity across time and across frequencies. Retrospective and longitudinal. All children with cleft palate born from 1991 to 1993 were included in the study (n = 58). Audiological and otological data were reviewed at 7, 10, 13, and 16 years of age. The group was divided by cleft type (24 unilateral cleft lip and palate, 23 cleft palate only, and 11 bilateral cleft lip and palate). The prevalence of abnormal middle ear status decreased significantly with age. When comparing cleft types, the isolated cleft palate group presented with a significantly lower prevalence of abnormal middle ear status than the other groups at 7 and 16 years of age (21% as compared to 32% in the unilateral group and 38% in the bilateral group). The pure-tone average improved with age, while the high-frequency pure-tone average did not. When cleft types were compared, the bilateral group demonstrated significantly poorer hearing in the high frequencies than the other groups. Children with cleft palate need regular audiological and otological follow-up to ensure management is appropriate and timely. The increased hearing thresholds in the high frequencies may be due to the increased episodes of OME.

Adopted children with cleft lip and/or cleft palate form a diverse group of patients. Due to increased age at palatal repair, adopted children have a higher risk of velopharyngeal insuffiency and poor speech outcome. Delayed palate repair may also lead to longer lasting Eustachian tube dysfunction. Decreased function of the Eustachian tube causes otitis media with effusion and recurrent acute otitis media, which can lead to other middle ear problems and hearing loss. One-hundred-and-thirty-two adopted children treated by the Cleft palate team in Wilhelmina Children's Hospital during January 1994 and December 2014 were included. Retrospectively, middle ear findings, the need for ventilation tube insertion and hearing during childhood were assessed. Findings were compared with 132 locally born children with cleft lip and/or cleft palate. Adopted children had a mean age of 26.5 months old when they arrived in our country. After the age of two the total number of otitis media with effusion episodes and the need for ventilation tube placement did not significantly differ among adopted and non-adopted children. Adopted children had significantly more tympanic membrane perforations. Hearing threshold levels normalized with increasing age. Although within normal range, adopted children showed significantly higher pure tone averages than locally born children when they were eight to ten years old. In general, adopted patients with cleft lip and/or cleft palate did not have more middle ear problems or ventilation tubes during childhood. However, theyhave more tympanic membrane perforations.
