This study investigated the masking-level difference (MLD) and auditory brainstem response (ABR) in a group of children with a history of otitis media with effusion (OME) and a control group of children with no known history of ear disease. All children had normal hearing at the time of testing. The main goal of the study was to determine whether there was an association between a reduced MLD in the OME children and an abnormal ABR (in terms of prolonged absolute or interwave intervals, or interaural differences in the ABR waveforms). The results indicated that the group of children having a history of OME had significantly reduced MLDs and had significantly prolonged waves III and V, and I–III and I–V interwave intervals. The correlations between MLD and delays in absolute wave or interwave intervals were not significant. However, some correlations between interaural asymmetries of the interwave intervals and the MLD were significant. The results suggest that the reduction in MLD found in children having a history of OME may be related to abnormal brainstem processing.

Objective To 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 Design Retrospective study. Setting Tertiary level referral audiologic center. Methods We 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. Results The 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). Conclusion Closure 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.

PURPOSE: To study the temporal auditory ordering and resolution abilities in children with and without a history of early OME and ROME, as well as to study the responses according to age. METHODS: A total of 59 children were evaluated, and all of them presented pure tone thresholds within the normal range at the time of the conduction of the hearing tests. The children were divided into two groups according to the occurrence of episodes of recurrent otitis media. Then, each group was divided into two subgroups according to age: 7- and 8-year olds, and 9- and 10-year olds. All children were assessed with standard tests of temporal frequency (ordination) and gaps-in-noise (resolution). RESULTS: For the temporal abilities studied, children with a history of otitis media presented significantly lower results compared to the control group. In the frequency pattern test, the correct answers increased with age in both groups. In the identification of silence intervals, the control group showed no change in threshold regarding to age, but this change was present in the group with a history of otitis media. CONCLUSION: Episodes of otitis media with effusion in the first year of life, recurrent and persistent in preschool and school ages, negatively influence the temporal ordering and resolution abilities.

Abstract Introduction The auditory structures of the brainstem are involved in binaural interaction, which contributes to sound location and auditory figure-background perception. Objective To investigate the performance of young adults in the masking level difference (MLD) test, brainstem auditory-evoked potentials (BAEPs) with click stimulus, and frequency-following response (FFR), as well as to verify the correlation between the findings, considering the topographic origin of the components of these procedures. Methods A total of 20 female subjects between 18 and 30 years of age, with normal hearing and no complaints concerning central auditory processing underwent a basic audiological evaluation, as well as the MLD test, BAEP and FFR. Results The mean result on the MLD test was of 10.70 dB. There was a statistically significant difference in the absolute latencies of waves I, III and V in the BAEPs of the ears. A change in the FFR characterized by the absence of the C, E and F waves was noticed. There was a statistically significant difference in the positive correlation of wave V in the BAEPs with the MLD. There was a statistically significant difference in the positive correlation of the mean MLD and the V, A and F components of the FFR. Conclusion The mean MLD was adequate. In the BAEPs, we observed that the click stimulus transmission occurred faster in the right ear. The FFR showed absence of some components. The mean MLD correlated positively with the BAEPs and FFR.

AbstractTo determine which factors were associated recurrence of ottitis media with effusion following grommet insertion, the casenotes of 323 who had a total of 485 operations for grommet insertion were reviewed. The incidence of repeat surgery was higher in those aged between four and six years, in those having grommet insertion between the months of July and October and in those cases in which the grommet was extruded within six months. Recurrence was not related to sex of patient, month of listing for surgery, adenoidectomy, tonsillectomy, length of time on the waiting list or past history of previous grommet insertion.

The outcome of otitis media with effusion (OME) in children is generally good. However, it is less clear in adults. All adult patients who had a ventilation tube inserted for OME at the Ipswich Hospital between 1996 and 1997 were studied. Of 53 patients studied, 28 had had a previous history of ventilation tube insertion. Furthermore, at 15–27 months following ventilation tube insertion, the ventilation tube had already extruded in 31 patients and the OME had already recurred in 19 of these. Endoscopic examination revealed that many patients still had evidence of inflammation at the lateral nasal wall (26.4 per cent) and at the eustachian tube orifice (51 per cent). There is also a strong history of atopy in the studied group and the skin prick test was positive in 57 per cent of the patients. This study shows that many patients with adult-onset OME have underlying pathology that could lead to recurrence of OME following ventilation tube extrusion.

AbstractThe hearing data from a sample of 73 children undergoing surgical treatment for chronic otitis media with effusion (OME) were analysed using a modification of the Glasgow Benefit Plot. All the patients had bilateral middle ear effusions confirmed at surgery. Using 20 dB average hearing level as the ‘cutoff’ point between normal and abnormal hearing, 65 (89 per cent) patients had binaural normal hearing, five (7 per cent) had monaural normal hearing and three (4 per cent) had bilateral hearing loss after surgery. However, 70 patients (96 per cent) were found to benefit from surgery. The cases with persistent hearing loss were re-examined to determine the cause of failure.

OBJECTIVE: To evaluate the effectiveness of laser myringotomy in otitis media with effusion (OME) in patients with nasopharyngeal carcinoma (NPC). STUDY DESIGN AND SETTING: Laser myringotomy was performed with a CO2 laser otoscope in 53 NPC patients (68 ears) and 32 non-NPC patients (37 ears). All patients had a history of OME. RESULTS: In the NPC group, 40% of ears developed persistent perforation, 37% had recurrent OME, and 23% were free of disease. In the non-NPC group, only 3% of ears developed persistent perforation, and 43% were free of disease. Significant differences in perforation and disease-free state were evident between the 2 groups. Tumor stage was found to be a significant determining factor for clinical outcome in NPC group. CONCLUSION: Laser myringotomy for NPC group carries a significantly higher risk of persistent perforation and lower rate of cure. This procedure may be considered for early staging NPC patients with serious OME symptoms.
