Endoscopic Adenoidectomy in Children With Otitis Media With Effusion and Mild Hearing Loss

ObjectivesSurgical 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.MethodsThis 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.ResultsThere 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).ConclusionAlthough 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.     

Sensitivity,specificity and predictive value of tympanometry in predicting a hearing impairment in otitis media with effusion

Children with otitis media with effusion (OME) need monitoring over time to identify persistence of disease and to assess their hearing thresholds as a surrogate of auditory disability. It would be useful if tympanometry could be used to predict those with an impairment. This study looked at 1153 children, aged between 3.25 and 6.75 years, referred for suspected OME. The inclusion of type C₂ tympanograms with type B tympanograms versus all other tympanogram types increased the sensitivity of detecting air-conduction thresholds and air-bone gaps of various magnitudes in the better hearing ear but lowered the specificity and the positive predictive value. Extending the pressure range to ?600 daPa and excluding the 30% of children with poor concentration on audiometry made no difference to the sensitivity and specificity. The results were the same for the poorer hearing ear. These findings are of practical help in monitoring children with OME. Thus taking an air-conduction average of 25 dB HL in the better ear as the level needing detection, if all children are audiometrically assessed then 100% of those with an impairment will be identified. Limiting audiometry to those with a bilateral type B tympanogram reduces the workload by 50%, but 90% of impaired children will still be detected. Limiting audiometry to those with type B or C₂ tympanograms reduces the workload to 69% of the sample, and 95% of impaired children will be identified. With such data, decisions as to how to allocate limited audiometric resources for monitoring children with OME are made easier.     

Chronic otitis media with effusion sequelae in children treated with tubes

OBJECTIVE: To determine incidence and prevalence of middle ear sequelae and abnormal tympanometry results among children with chronic otitis media with effusion (OME) who received standard treatment with tympanostomy tubes. DESIGN: Prospective cohort study. SETTING: Community clinic and academic medical center.Patients A total of 140 children followed up for 8 years after tube treatment. MAIN OUTCOME MEASURES: Tympanic membrane perforation, atrophy, retraction, hearing loss, myringosclerosis, low static admittance (SA) and broad-peaked tympanogram, high SA and narrow-peaked tympanogram, and negative tympanometric peak pressure. RESULTS: Annual incidence of sequelae was typically greater during 3 to 5 years than 6 to 8 years of follow-up. Greatest increases in incidence during the 5-year follow-up were for atrophy (67%), high SA and narrow-peaked tympanogram (70%), and retraction pocket (47%). Prevalence of these sequelae also increased over time, whereas low SA and broad-peaked tympanogram and negative tympanometric peak pressure decreased during follow-up. Sequela tended to become bilateral over time, and concordance of different sequelae in the same ear was low (kappa, 0.05-0.42). CONCLUSIONS: Annual incidence of sequelae decreased during follow-up. This finding parallels decreasing incidence of OME and tube placement as children mature and demonstrates that sequelae are more likely to develop during active acute and chronic OME. The cumulative effect of incidence resulted in few ears free of sequelae by 8 years of follow-up. Based on this cohort of healthy children with OME, although the risk of sequelae decreased over time, functional and morphologic sequelae were prevalent and may put children at risk for continuing middle ear problems as they grow into adolescence and adulthood.     

Grommets in otitis media: a 25-year follow up

Abstract

Background: This study is unique as it is the first study which can describe the long term sequelae of treatment of otitis media with effusion (OME) with insertion of grommets in the Primary Health Sector in Denmark.

Objectives: Eardrum pathology and hearing acuity 25 years after treatment of OME by insertion of grommets, in a private ear-, nose-, and throat practice.

Material and methods: 262 children with OME were treated from 1975 to 1978. The patients were re-examined by otomicroscopy, tympanometry and pure tone audiometry after 7.5, 12, and 25 years.

Results: Hearing level, flaccida retraction and incudo pexi was equivalent. For atrophy and myringosclerosis no equivalence was shown using 95% confidence intervals. Tympanometry was fairly unchanged.

Conclusion and significance: The insertion of a grommet in treating OME has no influence on hearing acuity in the long term. The prevalence of myringosclerosis and atrophy was unchanged in 70–80% of the eardrums. Most important is that the small increase in myringosclerosis and atrophy does not seem to influence the hearing acuity. We show that long term sequelae from the Primary Health Sector are similar to those from the Secondary Health sector.     

Risk factors for chronicity in childhood otitis media with effusion

One hundred and ninety-one children who presented to the author’s clinic with otitis media with effusion (OME) over a 2-year period (1986–1988) have been studied prospectively. Resolution of their OME was considered to have occurred when they had normal findings on pneumatic otoscopy, tympanometry and audiometry on at least two occasions 6 months apart and had subjectively normal hearing in between. The number of operations performed during the course of the disease was used as a surrogate for chronicity. Children with a history of previous aural discharge at presentation were significantly more likely to have chronic OME (P = < 0.02).     

Endoscopic examination of the larynx: is breathiness dependent on glottic area?

Hypothesis: Hearing tests performed in General Practice at the 3½-year developmental assessment do not correlate with objective measures of otitis media with effusion (OME: ‘glue ear’). Subjects: One hundred and thirty-nine consecutive children attending the 3½-year developmental assessment of four General Practitioners in a single inner-city practice. Outcome measures: The main outcome measure was the presence or absence of effusion as determined by the ‘gold standard’ of type B and C2 tympanograms bilaterally. Independent variables were standard toy test performed by the four GPs, parental assessment of hearing on the test day, the occurrence of two or more documented episodes of otitis media, presence of a smoking parent in the dwelling place and otoscopic findings (glue/no glue) determined by the GP performing the test. Results: The incidence of bilateral OME, as determined by tympanometry, in this population of 3½-year olds was 28%. Forward stepwise linear regression analysis indicated that the only statistically significant independent variable to correlate with tympanometric findings of OME was the GP’s hearing test (P = 0.003). Conclusion: Carefully performed GP hearing tests appear to be good predictors of OME in 3½-year olds, and should continue.     

Multifrequency tympanometry in adults with otitis media with effusion

We compared the diagnostic values of multifrequency tympanometry (MFT) and conventional 226-Hz tympanometry in adults with otitis media with effusion (OME) and discuss whether the resonant frequency (RF) can be used as a reliable method in adults with OME. Prospective study was designed to compare the normal hearing group and the group with OME. In the OME group (n = 85), conductive or mixed hearing loss was found, air-bone gap was more than 10 dBHL, and acoustic reflex was not elicited. In the normal hearing group (n = 36), pure tone threshold was less than or equal to 15 dBHL and air-bone gap was less than 10 dBHL. Levene's test was used to compare the difference between the OME group and the normal hearing group on day1, day15, day30, day90, respectively. The relationship among multifrequency tympanometry, 226-Hz tympanometry and acoustic reflex test in ears recovering from OME was also investigated. A statistically significant decrease in RF value was found in ears with OME compared to normative data. In follow-up visits, both the RF values and the percentage of type A tympanograms increased while the percentage of type B and C tympanograms decreased. A high agreement between middle ear resonant frequency test and acoustic reflex test in ears recovering from OME was found. The resonant frequency test provides more detailed information than the 226-Hz tympanometry. Multifrequency tympanometry may be a more sensitive and objective diagnostic tool in adults with OME.     

Sequelae of otitis media with effusion among children with cleft lip and/or cleft palate

Otitis media with effusion (OME) is common among children with cleft palate, and may lead to such long-term consequences as hearing loss, tympanic membrane retraction, and chronic otitis media (COM). In total, 104 children with cleft lip and/or palate treated for OME at our institution were reviewed. Mean duration of follow-up was 6.9 years, and mean age at latest follow-up was 9.6 years. The incidence of COM was 19%, and the incidence of cholesteatoma was 1.9%. Ears showing such long-term sequelae of OME as hearing loss, tympanic membrane retraction, and chronic otitis media, were noted to have undergone a significantly greater number of ventilation tube insertions than ears not showing these sequalae. Our findings would suggest that a conservative approach to the management of OME in children with cleft palate is more likely to be beneficial in the long term.     

Otitis media with effusion: Recurrence after tympanostomy tube extrusion

Objective

The incidence rate of recurrence of otitis media with effusion (OME) in children after tympanostomy tube extrusion and the relationship between recurrence and tube retention time was investigated. Also relationship between recurrence rate and initial age of tube insertion was analysed.

Study Design

A retrospective case series of patients who had tympanostomy tube insertion.

Methods

A total of 91 children (169 ears) were reviewed. Ears of children divided into three groups according to retention time of tympanostomy tubes. Group I: tympanostomy tube retention time less than 6 months. Group II: tympanostomy tube retention time 6 months to 12 months. Group III: tympanostomy tube retention time 12 months or more.

Results

OME recurrence rate after tube extrusion was 20.7% in the study. The longer the tympanostomy tube retention time was the lower was the recurrence rate of OME. The comparison of the three groups indicated that recurrence rates were higher in group I (36.54%), than in group II (17.74%) and in group III (9.1%). There were statistically significant differences in recurrence rates between group I and group III, and between group I and II (p < 0.05, p < 0.05). However, the difference in recurrence rates between group II and group III was statistically not significant (p > 0.05). In the preschool age group and school age group, the recurrence rates were 5.5% and 15.4%, respectively. There was no significant difference between these two groups (p > 0.05). OME recurrence was observed in 9.9% of males and in 11% of females. There was no significant difference in recurrence rates between males and females (p > 0.05).

Conclusion

After extrusion of tympanostomy tube, children should be followed-up regularly for recurrence of OME. The shorter the retention time of tympanostomy tubes was the higher was the recurrence rate. For the treatment of OME the ideal type of tubes should have the lowest complication and recurrence rates. Further studies are needed to ascertain the relationship between the incidence of OME and optimal tympanostomy tubes duration of tube stay in tympanic membrane. Therefore, new studies with larger series are necessary to investigate the correlation between the recurrence rates and different tympanostomy tubes after extrusion of tubes.     

Sequelae of otitis media with effusion among children with cleft lip and/or cleft palate1

Otitis media with effusion (OME) is common among children with cleft palate, and may lead to such long‐term consequences as hearing loss, tympanic membrane retraction, and chronic otitis media (COM). In total, 104 children with cleft lip and/or palate treated for OME at our institution were reviewed. Mean duration of follow‐up was 6.9 years, and mean age at latest follow‐up was 9.6 years. The incidence of COM was 19%, and the incidence of cholesteatoma was 1.9%. Ears showing such long‐term sequelae of OME as hearing loss, tympanic membrane retraction, and chronic otitis media, were noted to have undergone a significantly greater number of ventilation tube insertions than ears not showing these sequalae. Our findings would suggest that a conservative approach to the management of OME in children with cleft palate is more likely to be beneficial in the long term.     

Eustachian tube insufflation with thermal water: Effectiveness in the treatment of pediatric otitis media with effusion

PurposeOtitis media with effusion (OME) is the most common ear disease in childhood. The hearing loss associated with OME impacts on children's language development and behavior. Eustachian tube insufflation are among possible treatments for OME, but data regarding their effectiveness are scarce. The aim of this investigation was to analyze the effect of inhalatory thermal therapy and Eustachian tube insufflation in a consecutive cohort of pediatric patients with OME.Materials and methodsSeventy-four pediatric patients referred for OME to the thermal medical center “La Contea” (Battaglia Terme, Padova, Italy) were considered. Data from tympanometry and pure tone audiometry performed immediately before (T0), at the end of treatment (T1) and at a follow-up control (T2) were analyzed.ResultsData from 148 ears were available. The pressure values of tympanometry significantly improved from T0 to T1 (p = 0.0001), and further improvement was recorded at T2, when 60.8% of patients had normal tympanograms. A significant gain of the air-conduction threshold in the T0-T2 interval was observed (p = 0.0001). At otoscopy, a significant reduction of tympanic membranes with fluid or air-fluid levels presence (p < 0.00001) and a significant increase of normal tympanic membranes (p = 0.0001) were found.ConclusionEustachian tube insufflation represented a well-tolerated and effective treatment in children with OME. Further investigations should deepen these results in randomized, double-blind settings, possibly with long-term follow-up periods. A quality-of-life and cost-effectiveness evaluation of this treatment approach for pediatric OME could be helpful for public health decision-making.     

Otitis media with effusion in children: Pathophysiology,diagnosis, and treatment. A review

Otitis media with effusion (OME) is a frequent paediatric disorder. The condition is often asymptomatic, and so can easily be missed. However, OME can lead to hearing loss that impairs the child's language and behavioural development. The diagnosis is essentially clinical, and is based on otoscopy and (in some cases) tympanometry. Nasal endoscopy is only indicated in cases of unilateral OME or when obstructive adenoid hypertrophy is suspected. Otitis media with effusion is defined as the observation of middle-ear effusion at consultations three months apart. Hearing must be evaluated (using an age-appropriate audiometry technique) before and after treatment, so as not to miss another underlying cause of deafness (e.g. perception deafness). Craniofacial dysmorphism, respiratory allergy and gastro-oesophageal reflux all favour the development of OME. Although a certain number of medications (antibiotics, corticoids, antihistamines, mucokinetic agents, and nasal decongestants) can be used to treat OME, they are not reliably effective and rarely provide long-term relief. The benchmark treatment for OME is placement of tympanostomy tubes (TTs) and (in some cases) adjunct adenoidectomy. The TTs rapidly normalize hearing and effectively prevent the development of cholesteatoma in the middle ear. In contrast, TTs do not prevent progression towards tympanic atrophy or a retraction pocket. Adenoidectomy enhances the effectiveness of TTs. In children with adenoid hypertrophy, adenoidectomy is indicated before the age of 4 but can be performed later when OME is identified by nasal endoscopy. Children must be followed up until OME has disappeared completely, so that any complications are not missed.     

Long-term effects of otitis media with effusion on language,reading and spelling

The long-term effects of early OME on language and educational attainment were studied in 47 children of 7–8 years of age who had participated in earlier pre-school study¹ on otitis media with effusion (OME) and language development. At pre-school age OME was diagnosed by quarterly tympanometric screens (maximum nine) and language was assessed by a standard Reynell gtest. At school age the ears of the children were assessed by otomicroscopy, tympanometry and audiometry, and the development status by several language, reading and spelling tests. The association between early OME and language development found at pre-school age was no longer present at school age.     

Pacific Islands families study: the prevalence of chronic middle ear disease in 2-year-old Pacific children living in New Zealand

OBJECTIVE: The aim of this study was to determine the prevalence of chronic middle ear disease in 2-year-old Pacific children living in New Zealand. METHODS: The data were gathered as part of the Pacific Islands Families: First Two Years of Life (PIF) Study in which 1001 two year olds were screened using tympanometry to identify children at risk for otitis media with effusion (OME) and other otological disorders. Those failing the screening tests were referred to Manukau Superclinic where they had a further tympanometry test, and if they failed this test, were followed up with a comprehensive otological examination by an otolaryngologist using otomicroscopy and pneumatic otoscopy. RESULTS: Bilateral otitis media with effusion (OME) was the most common abnormality detected (N=102) with further cases of unilateral OME (N=8), and unilateral OME resolving (N=2). Other cases of OME were associated with acute otitis media (AOM), impacted wax (N=1), perforation (N=1), and mild retraction (N=2). Overall there were 118 children with unilateral or bilateral OME. AOM of any form was seen in nine cases. Retraction of the tympanic membrane was seen in 26 cases. The population prevalence among Pacific 2-year-old children was estimated as 25.4% for OME, 1.9% for AOM, and 26.9% for OME or AOM. CONCLUSIONS: These findings reveal that over 25% of Pacific Island 2-year-old were affected by OME and recommend the consideration of national screening for OME and other otological disorders at this earlier age.     

Extensive acquired cholesteatoma in children: when the penny drops

OBJECTIVES: To determine the factors associated with the diagnosis of acquired cholesteatoma (AC) in children, we performed a retrospective chart review at a tertiary care center. METHODS: We reviewed children with a diagnosis of AC that extended beyond the mesotympanum in the presence of a nonintact tympanic membrane who underwent surgical treatment over a 14-year period. RESULTS: There were 116 children (78 male, 38 female) between 3 and 18 years of age (mean, 9.5 years). Their average period of management in a specialist otolaryngology clinic before the diagnosis of cholesteatoma was made was 3.2 years, and 68% of the children had previously undergone insertion of tympanostomy tubes. Symptoms and signs included chronic otorrhea (59%), recurrent acute otitis media (58%), and conductive hearing loss (51%). The diagnosis of AC was eventually made after office otoscopy (26%), temporal bone computed tomography (24%), or examination under anesthesia (17%). In 33% of children, the diagnosis was made only after surgical exploration of the middle ear and mastoid. CONCLUSIONS: Our data underscore the importance of maintaining a high index of suspicion for AC in managing children with long-standing otologic symptoms, and considering otomicroscopy, computed tomographic scanning, or tympanomastoid exploration if medical treatment fails.     

Autoinflation for treatment of persistent otitis media with effusion in children: A cross-over study with a 12-month follow-up

Objectives

The aims of the present study were to evaluate the efficacy of and compliance with a new device for autoinflation in the treatment of persistent otitis media with effusion (OME) in young children.

Methods

Forty-five children with persistent OME with a bilateral type B or C2 tympanogram for at least three months and history of subjective hearing loss, waiting for grommet surgery, were randomised to a treatment and a control group. Twenty-three children aged between three and eight years started as the treatment group with the new device for autoinflation. Another 22 children, aged between two and eight years were included as controls. After a period of four weeks, a cross-over was performed. Both groups underwent otomicroscopy, tympanometry and audiometry at inclusion and after one and two months for the evaluation of treatment efficiency. The primary outcome measurements were improvement in middle-ear pressure and hearing thresholds at eight weeks. Both groups were then followed up for another 10 months.

Results

In the treatment group, the mean middle-ear pressure for both ears and the mean hearing thresholds for the best ear improved by 166 daPa (p < 0.0001) and 6 dB (p < 0.0001), respectively after four weeks, while in the control group, non-significant alterations were observed. After the cross-over of the control group to treatment, equivalent improvements in the mean middle-ear pressure and the mean hearing thresholds of 187 daPa (p < 0.0001) and 7 dB (p < 0.01), respectively were achieved also in this group. After treatment in both groups at eight weeks, four of 45 children were submitted to grommet surgery. During the long-term follow-up another five children were submitted to surgery due to recurrence of disease. All the children managed to perform the manoeuvre and no side-effects were detected.

Conclusion

The device demonstrated efficiency in improving both middle-ear pressure and hearing thresholds in most children after four weeks of treatment. It might therefore be possible to consider this method of autoinflation in children with persistent OME during the watchful waiting period.     

A comparison of outcomes following tympanostomy tube placement or conservative measures for management of otitis media with effusion

We obtained the charts of 183 patients (197 ears) who had undergone surgery for chronic otitis media (COM), and we reviewed their otic histories to analyze the series of events that ultimately culminated in surgery. All ears had originally been treated for otitis media with effusion (OME); 125 ears had been treated with tympanostomy tube placement, and 72 ears had been treated with conservative measures. Our goal was to compare the influence that these two strategies had on the subsequent development of COM and its sequelae (i.e., retraction pockets, tympanic membrane perforations, and cholesteatomas) and thereby determine which strategy is preferable. We found that although retraction pockets developed in a significantly higher proportion of the tympanostomy-treated ears than the conservatively treated ears (58 vs. 35%; p < 0.01), a significantly greater percentage of retractions in the tympanostomy-treated ears were mild and situated in the anterior part of the tympanic membrane (52 vs. 32%; p < 0.05). Moreover, severe retractions were significantly more common in the conservatively treated ears (40 vs. 16%; p < 0.02); the incidence of complete retractions in the two groups of ears was similar (tympanostomy: 32%; conservative treatment: 28%). Cholesteatomas developed in a significantly lower percentage of tympanostomy-treated ears (67 vs. 81%; p < 0.05), and the incidence of large cholesteatomas that involved the tympanic and mastoid cavities was likewise significantly lower in these ears (44 vs. 69%; p < 0.05). There was no significant difference in the incidence of tympanic membrane perforations. Finally, even though all of these ears eventually required surgery for COM, the tympanostomy-treated ears required significantly fewer repeat surgeries (16 vs. 28%; p < 0.05) and significantly fewer radical modified tympanomastoidectomies (30 vs. 44%; p < 0.05). Therefore, we conclude that myringotomy with insertion of tympanostomy tubes to treat OME is superior to conservative treatment.     

Uncommon and unusual complications of otitis media with effusion

Some complications of otitis media with effusion (OME) are not obvious and not always associated with otitis media by physicians and patients; the authors propose to call them 'unusual complications', although they may be quite frequent. Complications such as dizziness, clumsiness and behavioural disorders are classified in this group. Other complications are rare and uncommon such as sensorineural hearing loss and cholesteatoma. Some of these sequelae are structural, others more functional. The impact of OME on complex functions such as language, learning or behaviour is still controversial but seems to have been underestimated until now. Not only withholding treatment in children with OME may cause complications but also the treatment of OME may lead to sequelae, although serious side effects caused by the treatment of OME are rare. In this literature review, the epidemiology, importance and diagnosis of the uncommon and unusual complications of OME will be discussed.     

Transforming growth factor-β expression in otitis media with effusion

Objective: To characterize the existence and role of transforming growth factor-β (TGF-β) in otitis media with effusion (OME). Study Design: Retrospective. Methods: The levels of two major TGF-β isoforms, TGF-β1 and TGF-β2, in the middle ear effusions (MEEs) of 44 children were evaluated using enzyme-linked immunospecific assays (ELISAs). Forty-eight MEEs were separated into three clinically relevant groups (i.e., serous, mucoid, and purulent), and TGF-β levels were correlated with clinical parameters of disease for these MEEs. Results: Both TGF-β1 and TGF-β2 were present in the samples. Mean levels of TGF-β1 (920.36 ± 437.75 pg/mg total protein) were generally 100-fold greater than those of TGF-β2 (9.65 ± 11.19 pg/mg total protein). TGF-β1 levels were elevated in association with a history of previous tympanostomy tube placements (TTPs) (P = .029) and mucoid effusions (P = .042). TGF-β2 levels were elevated in association with a history of previous TTPs (P = .100) and chronic (i.e., serous or mucoid) effusions (P = .003). Conclusions: TGF-β1 is present in the MEEs of children with OME. Furthermore, TGF-β1 and TGF-β2 levels were elevated differentially in the presence of chronic disease indicators in OME, suggesting that these isoforms may have differing roles in the inflammatory processes that characterize OME.
