Hearing Outcomes in Failed Newborn Hearing Screening Infants With and Without Chronic Serous Otitis.

To identify outcomes in hearing loss (HL) diagnosis and intervention in infants with a failed newborn hearing screen (NBHS) and otitis media with effusion (OME) compared to those with failed NBHS and without OME. Retrospective review. Tertiary medical center. A chart review was performed on infants referred to Primary Children's Hospital for failed NBHS from 2012 to 2018. Eighty infants with failed NBHS and OME and 55 with failed NBHS and no OME were included. Incidence of permanent HL along with the age of HL confirmation and early intervention (EI) enrollment were compared. The incidence of OME in infants with failed NBHS was 59.3%. Fifty-six percent of infants with OME and 12.5% of those without OME did not receive definitive hearing confirmation in either ear due to loss to follow-up or insufficient audiometric assessment. Permanent HL was identified in 11.3% (n = 9) of infants with OME and in 20.0% (n = 11) of those without OME. Infants with OME were significantly older at the time of HL confirmation (4.2 ± 2.1 months) and EI enrollment (5.4 ± 2.5 months) compared to those without OME at the time of HL confirmation (1.0 ± 1.0 months; p < .001) and EI enrollment (2.6 ± 1.8 months; p = .04). Infants with failed NBHS and OME are highly susceptible to a significant delay in HL confirmation or lack of confirmatory hearing tests. Timely OME resolution with earlier ventilation tube insertion by 3 months of age and follow-up audiologic assessment is recommended.

Antibiotics for otitis media with effusion in children.

Otitis media with effusion (OME), one of the most common diseases in early childhood, is a self-limited illness1 with an estimated recurrence rate of 50% within 24 months2 . OME is characterized by an accumulation of fluid in the middle ear without symptoms or signs of acute infection.3 In most cases OME causes mild hearing impairment for a short period. OME in the pediatric population can lead to diminished hearing which in theory could hinder early learning. Some studies have shown an association with adult hearing loss as well.4 In one study, for instance, OME and recurrent otitis media before the age of 3 were weakly associated with worse classroom concentration, mathematical skills, oral performance and reading skills5 .

Effects of COVID-19 Lockdown on Otitis Media With Effusion in Children: Future Therapeutic Implications.

ObjectiveTo evaluate the role of social isolation during the lockdown due to the SARS-CoV-2 outbreak (severe acute respiratory syndrome coronavirus 2) in modifying the prevalence of otitis media with effusion (OME) and the natural history of chronic OME.Study DesignRetrospective study.SettingTertiary level referral audiologic center.MethodsWe assessed the prevalence of OME among children aged 6 months to 12 years who attended the outpatient clinic for hearing or vestibular disorders during 2 periods before the lockdown, May-June 2019 (n = 350) and January-February 2020 (n = 366), and the period immediately after the lockdown, May-June 2020 (n = 216). We also compared the disease resolution rates between a subgroup of children with chronic OME (n = 30) who were diagnosed in summer 2019 and reevaluated in May-June 2020 and a similar subgroup (n = 29) assessed in 2018-2019.ResultsThe prevalence of OME in this clinic population was 40.6% in May-June 2019, 52.2% in January-February 2020, and 2.3% in May-June 2020. Children with chronic OME had a higher rate of disease resolution in May-June 2020 (93.3%) than those examined in May-June 2019 (20.7%, P < .001).ConclusionClosure of schools and the physical distancing rules were correlated with a reduction in the prevalence of OME and favored the resolution of its chronic forms among children who attended the outpatient clinic. These data could suggest that in the presence of chronic OME, keeping young children out of group care settings for a period might be beneficial to allow for OME resolution.

Long-term outcomes in children with and without cleft palate treated with tympanostomy for otitis media with effusion before the age of 2 years

Background Long-term outcomes of children with and without cleft palate receiving early treatment for otitis media with effusion (OME) are unclear. Objectives To compare long-term otological and audiological outcomes between children with and without cleft palate treated with tympanostomy for OME before the age of 2 years. Material and methods Ninety-five children (180 ears) with cleft palate (study group) and 97 children (185 ears) without (control group) were followed-up to a maximum age of 7 years. We retrospectively analyzed the audiological outcomes at the age of 7 years, and the otological outcomes at the last examination. Results The percentages of children with OME resolution before the age of 7 years were 47.4% and 60% in the study and control groups, respectively, and those of ears with healed tympanic membrane were 71.7% and 79.5% in the corresponding groups. Significantly more ears were subjected to retympanostomy in the study (31.1%) than in the control group (21.6%). Mean pure-tone average (0.5‒4 kHz) was 15.6 dB HL and 14.3 dB HL for the corresponding groups. Conclusions/significance Otological and audiological outcomes in both groups were similar. The audiological prognosis was favorable regardless of the cleft palate condition.

The safety of posterior tympanotomy in otitis media with effusion during cochlear implantation: clinical retrospective cohort study

Background Posterior tympanotomy (PT) is an important step in cochlear implant (CI) surgery, as it is the main access to the round window. Some CI candidates, especially children, may have concomitant otitis media with effusion (OME) which may result in technical issues during PT. There is still a debate whether to wait for OME resolution preoperatively or to proceed to surgery with suspected difficulties. Aims/Objective To evaluate the safety of PT during CI surgery in patients with OME. Material and Methods we included 102 consecutive pediatric candidates in this retrospective study with an age range of 12 months to 6 years. All the patients underwent CI surgery using trans-mastoid, PT to access round window (RW) area. We investigated the effect of the pathology caused by OME on the operative procedure in PT and post-operative consequences. The Results out of 102 patients included in this study, there were 22 patients with OME who had unilateral cochlear implantation with no major operative or post-operative events. Nevertheless, some minor intra operative events and difficulties were encountered. Conclusion and Significance The presence of OME in CI surgery indicates possible surgical challenges such as difficult PT, minor intra-operative risks and with no major post-operative events.

Long-Term Otitis Media Outcomes in Infants With Early Tympanostomy Tubes.

To review the otologic outcomes of infants who failed the newborn hearing screen (NBHS) and received early tympanostomy tubes for otitis media with effusion (OME). Retrospective case series. Tertiary care pediatric hospital. Consecutive patients (2007-2018) who failed an NBHS and required tympanostomy tubes before 6 months of age were included. Variables including hearing loss and otitis media risk factors, episodes of acute otitis media (AOM), number of subsequent tympanostomy tubes, and posttympanostomy tube audiogram results were recorded. The cohort included 171 patients. Median age at referral to otolaryngology was 2.7 months. Sensorineural hearing loss (SNHL) was subsequently identified in 22 (12.9%) of infants after resolution of the effusion. The peak incidence of AOM was during the second year of life (1-1.9 years), with a median of 1 episode. Ninety-five patients (55.6%) had replacement of tubes, 41 of 171 (24.0%) had 2 or more additional sets of tubes, and long-term tubes were eventually placed in 8 of 95 (8.4%) patients. Craniofacial anomalies were identified in 43.3% of patients. Tube replacement (hazard ratio, 3.00; 95% CI, 1.95-4.63; P < .01, log-rank) and AOM (β, 1.04; 95% CI, 0.43-1.65; P = .04, ordered logistic regression) were more common, and SNHL less common (odds ratio, 0.17; 95% CI, 0.031-0.61; P < .01, logistic regression), in children with craniofacial anomalies. OME is a common cause of failed NBHS. A notable proportion was subsequently found to have SNHL, reiterating the need for postoperative hearing assessments. Infants meeting indication for early tympanostomy tubes for resolution of OME have a high incidence of recurrent AOM and require subsequent tubes.

Resolution of Otitis Media With Effusion in Children With Cleft Palate Followed Through Five Years of Age.

To describe the temporal pattern of otitis media with effusion (OME) resolution for a cohort of nonsyndromic cleft palate children enrolled before palatoplasty and followed through 5 years of age. This is a prospective, longitudinal study of the time course for OME resolution in infants and children with palatal clefts. Cleft Palate Craniofacial Center of a tertiary care pediatric hospital. This study included 52 children with cleft palate (29 boys, 45 white, Veau 1 through 4) who had a Furlow-type palatoplasty between 10 and 24 months of age performed by one of six surgeons. Standard cleft palate management was supplemented with study visits to the research clinic pre- and postpalatoplasty and then yearly to 6 years of age for assessments of middle ear status by interval history, otoscopy, and tympanometry. The main outcome measure was age at otitis media resolution defined as the age in years at the first in a sequence of "disease-free" diagnoses not interrupted or followed by any other diagnosis. The cumulative percent OME resolution for ears/children at ages <1, 1, 2, 3, 4, 5 years was 4.1/4.4, 14.3/10.9, 31.6/21.7, 45.9/37.0, 56.1/50.0, and 70.4/60.9%. OME resolution followed a simple linear time curve with slopes of 13.5% (confidence interval [CI] = 12.2% to 14.8%, r(2) = .99) and 11.9% (CI = 10.1% to 13.6%, r(2) = .99) resolutions per year for ears and children, respectively. There is a natural, age-related pattern of resolution for persistent OME that affects most infants and young children with cleft palate that is not affected by palatoplasty.

Antibiotics for otitis media with effusion in children.

Otitis media with effusion (OME) is characterised by an accumulation of fluid in the middle ear behind an intact tympanic membrane, without the symptoms or signs of acute infection. Since most cases of OME will resolve spontaneously, only children with persistent middle ear effusion and associated hearing loss potentially require treatment. Previous Cochrane reviews have focused on the effectiveness of ventilation tube insertion, adenoidectomy, nasal autoinflation, antihistamines, decongestants and corticosteroids in OME. This review, focusing on the effectiveness of antibiotics in children with OME, is an update of a Cochrane review published in 2012. To assess the benefits and harms of oral antibiotics in children up to 18 years with OME. The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2016, Issue 3); PubMed; Ovid EMBASE; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 14 April 2016. Randomised controlled trials comparing oral antibiotics with placebo, no treatment or therapy of unproven effectiveness in children with OME. We used the standard methodological procedures expected by Cochrane. Twenty-five trials (3663 children) were eligible for inclusion. Two trials did not report on any of the outcomes of interest, leaving 23 trials (3258 children) covering a range of antibiotics, participants, outcome measures and time points for evaluation. Overall, we assessed most studies as being at low to moderate risk of bias.We found moderate quality evidence (six trials including 484 children) that children treated with oral antibiotics are more likely to have complete resolution at two to three months post-randomisation (primary outcome) than those allocated to the control treatment (risk ratio (RR) 2.00, 95% confidence interval (CI) 1.58 to 2.53; number needed to treat to benefit (NNTB) 5). However, there is evidence (albeit of low quality; five trials, 742 children) indicating that children treated with oral antibiotics are more likely to experience diarrhoea, vomiting or skin rash (primary outcome) than those allocated to control treatment (RR 2.15, 95% CI 1.29 to 3.60; number needed to treat to harm (NNTH) 20).In respect of the secondary outcome of complete resolution at any time point, we found low to moderate quality evidence from five meta-analyses, including between two and 14 trials, of a beneficial effect of antibiotics, with a NNTB ranging from 3 to 7. Time periods ranged from 10 to 14 days to six months.In terms of other secondary outcomes, only two trials (849 children) reported on hearing levels at two to four weeks and found conflicting results. None of the trials reported data on speech, language and cognitive development or quality of life. Low quality evidence did not show that oral antibiotics were associated with a decrease in the rate of ventilation tube insertion (two trials, 121 children) or in tympanic membrane sequelae (one trial, 103 children), while low quality evidence indicated that children treated with antibiotics were less likely to have acute otitis media episodes within four to eight weeks (five trials, 1086 children; NNTB 18) and within six months post-randomisation (two trials, 199 children; NNTB 5). It should, however, be noted that the beneficial effect of oral antibiotics on acute otitis media episodes within four to eight weeks was no longer significant when we excluded studies with high risk of bias. This review presents evidence of both benefits and harms associated with the use of oral antibiotics to treat children up to 16 years with OME. Although evidence indicates that oral antibiotics are associated with an increased chance of complete resolution of OME at various time points, we also found evidence that these children are more likely to experience diarrhoea, vomiting or skin rash. The impact of antibiotics on short-term hearing is uncertain and low quality evidence did not show that oral antibiotics were associated with fewer ventilation tube insertions. Furthermore, we found no data on the impact of antibiotics on other important outcomes such as speech, language and cognitive development or quality of life.Even in situations where clear and relevant benefits of oral antibiotics have been demonstrated, these must always be carefully balanced against adverse effects and the emergence of bacterial resistance. This has specifically been linked to the widespread use of antibiotics for common conditions such as otitis media.

New therapeutic strategy for treating otitis media with effusion in postirradiated nasopharyngeal carcinoma patients

BackgroundPostirradiation otitis media with effusion (OME) is the most common radiotherapy-associated otologic complication associated with nasopharyngeal carcinoma (NPC). This study's aim was to evaluate the efficacy of laser myringotomy followed by intratympanic steroid injection (LMIS) for treating OME in postirradiated NPC patients. MethodsFrom August 2002 to January 2006, 27 newly diagnosed NPC patients who developed OME after a full course of radiotherapy were enrolled. Laser myringotomy was performed followed by once-weekly administration of steroids (0.5mL dexamethasone at a concentration of 5.0mg/mL) into the middle ear for 3 consecutive weeks. The success rate of dry eardrum perforation and the prognostic factors associated with OME resolution were analyzed. ResultsThe procedure was performed on 44 ears of 27 patients. The mean follow-up period was 37 weeks. Of the 44 ears, 23 (52.3%) developed persistent eardrum perforation, 18 (40.9%) developed recurrent OME, and three (6.8%) were disease-free on follow-up. Of the 23 ears with persistent eardrum perforation, 18 (78.3%) were diagnosed as dry perforation. The absence of pretreatment mastoiditis was an independent factor associated with OME resolution (p<0.001). ConclusionLMIS is a quick, minimally invasive, office-based technique that can be repeatedly performed to treat highly recurrent postirradiation OME, and it results in relatively slight pain to NPC patients. Long-lasting dry eardrum perforation allows for adequate middle ear ventilation and drainage and guarantees sustained relief from symptoms. The absence of preoperative mastoiditis is a favorable prognostic factor associated with OME resolution.

Otitis Media With Effusion

Otitis media with effusion (OME) is the major reason for failure of neonatal hearing screening. However, little is known about the impact on hearing status of OME in infants during the first months of life. Infants who failed universal newborn hearing screening. Prospective evaluation for the presence of OME, the degree of hearing loss and the disease evolution. Between 2007 and 2008, approximately 152 infants were referred because of unilateral or bilateral failure on universal newborn hearing screening with an automated auditory brainstem response device. Eighty-four (55.3%) had OME, 20 of them were lost to follow-up. The remainder 64 infants comprised 37 boys and 27 girls, with a median age of 49 days (range, 40-65 d) at admission. Auditory brainstem response thresholds were 50 dB nHL (range, 40-60) in both ears. A spontaneous resolution of OME was documented in 15 infants. In the remaining, hearing normalized after tympanocentesis or placement of ventilation tubes. Normal hearing could be ascertained in all children at a median age of 4.8 months (range, 3.3-7.8 mo). In the group of infants analyzed, no permanent hearing loss could be detected. OME is an important cause of transient, moderately severe hearing loss during the first months of life--a critical period for development of the auditory system. Active treatment should be considered if spontaneous resolution does not occur to prevent any delay in language acquisition and to exclude an underlying sensorineural hearing loss.

Oral or topical nasal steroids for hearing loss associated with otitis media with effusion in children.

Otitis media with effusion (OME) is common and may cause hearing loss with associated developmental delay. Treatment remains controversial. To examine the evidence for treating children with hearing loss associated with OME with systemic or topical intranasal steroids. We searched the Cochrane ENT Group Trials Register; CENTRAL; PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; mRCT and additional sources for published and unpublished trials. The date of the most recent search was 26 August 2010. Randomised controlled trials of oral and topical intranasal steroids, either alone or in combination with another agent such as an oral antibiotic. We excluded publications in abstract form only; uncontrolled, non-randomised or retrospective studies; and studies reporting outcomes by ears (rather than children). The authors independently extracted data from the published reports using standardised data extraction forms and methods. We assessed the quality of the included studies using the Cochrane 'Risk of bias' tool. We expressed dichotomous results as a risk ratio (RR) and continuous data as weighted mean difference (WMD), both with 95% confidence intervals (CI). Where feasible we pooled studies using a random-effects model and performed tests for heterogeneity between studies. In trials with a cross-over design, we did not use post cross-over treatment data. We included 12 medium to high-quality studies with a total of 945 participants. No study documented hearing loss associated with OME prior to randomisation. The follow-up period was generally limited, with only one study of intranasal steroid reporting outcome data beyond six months. There was no evidence of benefit from steroid treatment (oral or topical) in terms of hearing loss associated with OME. Pooled data using a fixed-effect model for OME resolution at short-term follow up (< 1 month) showed a significant effect of oral steroids compared to control (RR 4.48; 95% CI 1.52 to 13.23; Chi² 2.75, df = 2, P = 0.25; I² = 27%). Oral steroids plus antibiotic also resulted in an improvement in OME resolution compared to placebo plus antibiotic at less than one month follow up, using a random-effects model (RR 1.99; 95% CI 1.14 to 3.49; five trials, 409 children). However, there was significant heterogeneity between studies (P < 0.01, I² = 69%). There was no evidence of beneficial effect on OME resolution at greater than one month follow up with oral steroids (used alone or with antibiotics) or intranasal steroids (used alone or with antibiotics) at any follow-up period. There was also no evidence of benefit from steroid treatment (oral or topical) in terms of symptoms. While oral steroids, especially when used in combination with an oral antibiotic, lead to a quicker resolution of OME in the short term, there is no evidence of longer-term benefit and no evidence that they relieve symptoms of hearing loss. We found no evidence of benefit from treatment of OME with topical intranasal steroids, alone or in combination with an antibiotic, either at short or longer-term follow up.

The link between otitis media with effusion and allergy: A potential role for intranasal corticosteroids

We reviewed the evidence linking otitis media with effusion (OME) and atopy, with the goal of clarifying the possible role of intranasal corticosteroids (INSs) in OME treatment. In August 2009, the MEDLINE database was searched for primary studies on OME epidemiology, pathophysiology, and treatment. Relevant clinical guidelines were obtained. Interpreting OME research is complicated by variable disease definitions, patient populations, methodologies, and outcomes assessments, along with the possibility of spontaneous resolution. However, evidence links OME with atopic conditions including allergic rhinitis; observed prevalence of allergic rhinitis in patients with chronic or recurrent OME ranges from 24% to 89%. Such findings have prompted evaluations of common allergy medications for OME treatment. While short-term use of INSs alone or combined with antibiotics has shown benefit in some studies, more prolonged treatment protocols and long-term clinical outcomes will require critical assessment. Evidence suggesting epidemiologic and pathophysiologic links between allergy and OME has prompted investigation into a potential role for INSs in OME management, with promising initial results. Benefits of considering medical treatment in patients with OME prior to surgery include both the potential reductions in allergic inflammation and the naturally occurring spontaneous resolution of OME in these patients.

Adenoidectomy for otitis media in children

Adenoidectomy, surgical removal of the adenoids, is a common ENT operation worldwide in children with otitis media. A systematic review on the effectiveness of adenoidectomy in this specific group has not previously been performed. To assess the effectiveness of adenoidectomy versus non-surgical management or tympanostomy tubes in children with otitis media. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; mRCT and additional sources for published and unpublished trials. The date of the most recent search was 30 March 2009. Randomised controlled trials comparing adenoidectomy, with or without tympanostomy tubes, versus non-surgical management or tympanostomy tubes only in children with otitis media. The primary outcome studied was the proportion of time with otitis media with effusion (OME). Secondary outcomes were mean number of episodes, mean number of days per episode and per year, and proportion of children with either acute otitis media (AOM) or otitis media with effusion (OME), as well as mean hearing level. Tertiary outcome measures included atrophy of the tympanic membrane, tympanosclerosis, retraction of the pars tensa and pars flaccid and cholesteatoma. Two authors assessed trial quality and extracted data independently. Fourteen randomised controlled trials (2712 children) studying the effectiveness of adenoidectomy in children with otitis media were evaluated. Most of these trials were too heterogeneous to pool in a meta-analysis. Loss to follow up varied from 0% to 63% after two years.Adenoidectomy in combination with a unilateral tympanostomy tube has a beneficial effect on the resolution of OME (risk difference (RD) 22% (95% CI 12% to 32%) and 29% (95% CI 19% to 39%) for the non-operated ear at six and 12 months, respectively (n = 3 trials)) and a very small (< 5 dB) effect on hearing, compared to a unilateral tympanostomy tube only. The results of studies of adenoidectomy with or without myringotomy versus non-surgical treatment or myringotomy only, and those of adenoidectomy in combination with bilateral tympanostomy tubes versus bilateral tympanostomy tubes only, also showed a small beneficial effect of adenoidectomy on the resolution of the effusion. The latter results could not be pooled due to large heterogeneity of the trials.Regarding AOM, the results of none of the trials including this outcome indicate a significant beneficial effect of adenoidectomy. The trials were too heterogeneous to pool in a meta-analysis.The effects of adenoidectomy on changes of the tympanic membrane or cholesteatoma have not been studied. Our review shows a significant benefit of adenoidectomy as far as the resolution of middle ear effusion in children with OME is concerned. However, the benefit to hearing is small and the effects on changes in the tympanic membrane are unknown. The risks of operating should be weighed against these potential benefits.The absence of a significant benefit of adenoidectomy on AOM suggests that routine surgery for this indication is not warranted.

CO2 laser myringotomy in children with otitis media with effusion

The study aimed to evaluate the clinical application of CO2 laser myringotomy in children with otitis media with effusion (OME) under topical anaesthesia in an office setting. Laser myringotomy was performed with the CO2 laser Otoscan (OtoLAM) in 54 children (73 ears) with OME. The procedure on the tympanic membrane was performed under topical anaesthesia using Bonain's solution or 10 per cent Xylocaine (lidocaine) solution for 30 minutes before surgery. A circular perforation was created with a power of 15 W, single pulse duration of 200 msec and a scanned area of 1.9 mm in diameter. The mean healing time was 2.51 weeks (range 1-5 weeks). Effusion content was not a predictive prognostic factor for perforation healing time. Perforation location over anterior inferior or posterior inferior quadrants was not a predictive factor for perforation healing time. Xylocaine was the more effective anaesthestic. The OME resolution rate was 73 per cent. Laser myringotomy provides intermediate duration middle-ear ventilation. It could be beneficial in selected children with OME.

Screening children in the first four years of life to undergo early treatment for otitis media with effusion.

Otitis media with effusion (OME) is the most common cause of acquired hearing loss in childhood and has been associated with delayed language development and behavioural problems. This condition has a prevalence of about 20% at the age of two years, a time of rapid language development. It is most often asymptomatic. Effective treatment exists for clearing effusions. Some have argued, therefore, that children should be screened and treated early if found to have clinically important OME. However, there is a high rate of spontaneous resolution of effusions and for some children, effusions may represent a physiological response that does not reduce hearing significantly or impact negatively on language development or behaviour. Previous reviews of the effect of screening and treatment have included studies using non-randomised designs. The aim of this review was to assess evidence from randomised controlled trials about the effectiveness, on language and behavioural outcomes, of screening and treating children with clinically important OME in the first four years of their life. The focus was on the first four years of life because this is the time of most rapid language development. The consequences of hearing loss are likely to be most serious during this time. In addition, children of this age are least likely to be able to report or seek help for impaired hearing, particularly if these problems have a slow onset and are subtle. We searched the Cochrane Controlled Trials Register (the Cochrane Library Issue 1, 2002), MEDLINE (1966-2002) and EMBASE (1974-2002) (all in February 2002) and reference lists of all studies. We also contacted the first authors of the studies we included in this review. 1. Randomised controlled trials evaluating interventions for OME among children with OME identified through screening. 2. Comparison of outcomes for children randomised to be screened for OME and outcomes for children who were not randomised to be screened for OME. Two reviewers independently extracted data and assessed trial quality. We identified no trials comparing outcomes for children randomised to be screened for OME with outcomes for children who were not randomised to be screened for OME. We identified three trials evaluating interventions for OME among children with OME identified through screening. From these trials, we found no evidence of clinically important benefit in language development from screening and treating children with clinically important OME. Although there was a beneficial effect on the resolution of OME and improved hearing in the short-term (six months), this effect largely disappeared in the long-term (12 months). The identified randomised trials do not show an important benefit from screening of the general population of asymptomatic children in the first four years of life for OME on language development and behaviour.

Oral or topical nasal steroids for hearing loss associated with otitis media with effusion in children.

OME is common and may cause hearing loss with associated developmental delay. Treatment remains controversial. The effect of both systemic and intra-nasal steroids on effusions has been assessed by randomised controlled trials. To examine evidence for or against treating children with hearing loss associated with OME with systemic or topical nasal steroids. Searches were conducted in February 2000. We searched the Cochrane Controlled Trials Register using the terms 'otitis-media', 'otitis media with effusion', 'glue ear', or 'OME', and 'steroids', 'glucocorticoids, synthetic', 'glucocorticoids, topical', 'anti-inflammatory agents, steroidal'. EMBASE and MEDLINE were also searched for additional information. Randomised controlled trials of oral and topical nasal steroids, either alone or in combination with another agent such as an antibiotic, were included. publications in abstract form only since adequate appraisal was not possible; uncontrolled, non-randomised or retrospective studies; studies reporting outcomes with ears (rather than children) as the unit of analysis. Data were extracted from the published reports by the two authors independently (CCB and JH van der V) using standardised data extraction forms and methodology. The methodological quality of the included studies were independently assessed by the two authors using the scheme described in the Cochrane Handbook. Dichotomous results were expressed as an odds ratio using a fixed effects model together with the 95% confidence intervals. Continuous data were analysed using the weighted mean difference in a fixed effects model. Tests for heterogeneity between studies were performed using a Mantel-Haenszel approach. In trials with a cross over design, post-crossover treatment data were not used. No study prospectively documented hearing loss associated with OME prior to randomisation. Follow up was short term. No serious or lasting side effects were reported in the four studies that did mention side effects. Most comparisons involved small numbers of subjects. The odds ratio for OME persisting after short term follow up for children treated with oral steroids plus antibiotic compared to control plus antibiotic was 0.32 (95% CI 0.20 to 0.52). However there was significant heterogeneity between studies (p<0.01). Trends favoured steroids for most other comparisons, but confidence intervals included unity. There was no evidence of benefit for steroid treatment in the longer term, and no study assessed effect of steroid treatment on language development. There is evidence that steroids combined with an antibiotic lead to a quicker resolution of OME in the short term. However, there is not evidence for long term benefit from treating hearing loss associated with OME with either oral or topical nasal steroids. These treatments are therefore not recommended at the present time. Future studies should document hearing loss associated with OME before the start of study treatment. Follow up should be longer and ideally include symptom, audiometry and developmental outcomes. Data should not be presented with ears as the unit of analysis.

Steroids for otitis media with effusion: a systematic review.

Otitis media with effusion (OME) is common and may cause hearing loss with associated delayed language development in children. Treatment remains controversial. To examine evidence for or against treating OME with systemic or topical nasal steroids. We searched the Cochrane Controlled Trials Register using the terms otitis media; otitis media with effusion; glue ear; or OME and steroids; glucocorticoids; glucocorticoids, synthetic; glucocorticoids, topical; or anti-inflammatory agents, steroidal; or various combinations of these terms. EMBASE and MEDLINE were also searched. Randomized controlled trials of oral and topical nasal steroids, either alone or in combination with another agent such as an antibiotic, were included. Ten studies met the inclusion criteria. Data extraction and methodological quality assessment were performed by the 2 of us (C.C.B. and J.H.v.d.V.) independently, using standardized methods described in the Cochrane Collaboration Handbook. The odds ratio for OME persisting after short-term follow-up in children treated with oral steroids compared with a control was 0.22 (95% confidence interval, 0.08 = 0.63), and was 0.32 (95% confidence interval, 0.20 = 0.52) for children treated with oral steroids plus an antibiotic compared with a control plus an antibiotic. Trends favored steroids for most other comparisons, but confidence intervals included unity. Trends favored steroids for most other comparisons, but confidence intervals included unity. Steroids alone or combined with an antibiotic lead to a quicker resolution of OME in the short-term. However, there is no evidence for a long-term benefit from treating hearing loss associated with OME with either oral or topical nasal steroids. These treatments are, therefore, not recommended.
