Otitis media with effusion (OME) often results in hearing loss for children with the condition. In order to provide appropriate and effective audiologic management, it is important to understand the impact of OME on speech recognition ability when hearing loss is present. This study examined the speech recognition abilities of normal-hearing six- and seven-year-old children (n = 12) and adults (n = 12) using monosyllabic words and nonsense syllables presented at two levels of simulated conductive hearing loss characteristic of OME. Average speech recognition scores decreased as the degree of simulated conductive hearing loss increased. Both age groups scored significantly poorer for nonsense syllables than for monosyllabic words. In general, the children performed more poorly than the adults with the exception of the easiest listening condition for word stimuli. Furthermore, children appeared less able than adults to use their knowledge of familiar words to improve performance. These findings suggest that rehabilitative strategies may best be focused on combining familiarization techniques and amplification options.

Internal Carotid Arteries

The aberrant course of the intratympanic carotid artery is a rare congenital vascular anomaly. We report the case of a 7-year-old patient who presented with bilateral conductive hearing loss, originally attributed to otitis media with effusion. After myringotomy, massive pulsatile bleeding occurred on the right side. The bleeding was successfully controlled with packing without any residual complication. Imaging confirmed aberrant internal carotid arteries abutting the tympanic membranes bilaterally.

Background: Orofacial cleft is one of the most common congenital malformations of craniofacial region. Otitis media with effusion causing conductive hearing loss is a considerable challenge for many children with cleft lip and palate. The aim of this study was to evaluate the prevalence of hearing disorders and associated malformations in these patients. Methods: The research population consisted of patients with cleft palate, between years 2012 and 2014, who were referred to Children’s Medical Center and Vali-e-Asr hospital in Tehran, Iran. Otoscopic examination, tympanometry, pure tone audiometry and echocardiography were performed for each patient. Results: Among patients with cleft palate, 73% suffered from hearing disorders. There was no relationship between prevalence of hearing loss and sex, presence of other congenital anomalies and degree of cleft, but middle ear diseases were significantly higher in children younger than 2 years. Among patients with cleft lip or palate, 10% suffered from cleft lip, 63% suffered from cleft palate and 27% suffered from cleft lip and palate. There was at least one congenital anomaly in 53% of patients. Conclusion: This study demonstrates high prevalence of otitis media with effusion and conductive hearing loss in patients with cleft. However, audiologic problems are alleviated when patients become older.

Auditory brainstem responses (ABR) were recorded in 14 infants and toddlers and 12 school-age children with a previous history of recurrent otitis media with effusion (OME), or otoscopic and tympanometric evidence of persistent OME, or both. ABR tests were performed immediately before and after myringotomy and tympanostomy tube insertion in the younger subjects. For the school-age children, ABR tests were performed following otoscopy, tympanometry, and pure tone audiometry. The results demonstrate that the latency of both wave I and wave V of the ABR was sensitive (82% and 100%, respectively) to the presence of OME. Wave I also identified the absence of OME (specificity = 100%) whereas wave V did not (specificity = 25%). ABR latency was significantly decreased postoperatively in ears found to have OME, but not in ears found to have no OME. In the school-age subjects the ABR was used to predict the conductive hearing loss at 4000 Hz with less than a 20 dB error in virtually all subjects. The ABR latency delay was also found to be related to conductive hearing impairment at lower pure tone frequencies and to the average conductive loss at a variety of pure tone frequencies. Predictions of the presence of a conductive hearing loss from these relationships promise to be impressively accurate. The results suggest that the ABR can be a valuable tool for detecting the presence of conductive hearing impairment in infants and young children suspected to have OME and perhaps as an estimate of the degree of impairment.

Acrocephalosyndactyly (Apert syndrome) is a rare cranlosynostotic syndrome characterized by acrocephaly, syndactyly of the hands and feet, and—occasionally—-conductive hearing loss. We report three cases of conductive hearing loss in Apert syndrome. One patient was found to have bilateral stapes fixation. His daughter (the second case) had chronic bilateral otitis media with effusion. The third case involved a fixed Incus and hypomobile stapes. The management of these patients and a review of the literature are presented.

This experiment assessed the extent to which a peripheral hearing loss may confound interpretation of dichotic listening test results in assessment of central auditory deficit. A normal-hearing listener was tested monotically and dichotically with CV nonsense syllables in two conditions. In one, an EAR plug inserted in the auditory canal to simulate a unilateral conductive hearing loss. In the second, no plus was inserted. Syllables were presented with equal intensity to the two ears for dichotic testing and testing was conducted at several different intensities. With the plug inserted, both magnitude and direction of percent ear advantage varied with test intensity even when monotic speech recognition scores exceeded 95% for both ears. When dichotic tests are used to assess central auditory deficit in patients with peripheral hearing loss, we recommend that the test intensity be at least 10 dB from both the lower and upper knees of monotic performance-intensity functions.

Age Related Changes

A retrospective analysis to quantify age-related changes of the incudo-malleolar joint (IMJ) and incudo-stapedial joint (ISJ), and to analyse changes in the air-bone gap (ABG) with age, was performed. Defined histologic parameters of 153 IMJ and 106 ISJ from subjects aged from birth to 70 years were correlated to age. Additionally, audiograms of 1760 ears of 974 other subjects aged 20 to 80 years were retrospectively analysed and the ABG was correlated to age. The joint space (age group from 0 to 10 compared to 61 to 70 years) became significantly wider with age (IMJ: from a mean of 44 µm to 100 µm, p < 0.001; ISJ: from a mean of 28 µm to 69 µm, p < 0.009. The thickness of cartilage of the incus decreased in the first 20 years of life (IMJ, from a mean of 88 µm to 65 µm, p < 0.01; ISJ: from a mean of 44 µm to 35 µm, p < 0.01). The ABGs of younger ears (20–40 years) was significantly larger at 500 Hz compared to older ears (60–80 years) by 2–4 dB, while it was significantly smaller by 3–5 dB at 4000 Hz (p < 0.0017). Interindividual variations in all age groups were large for both analyses. The increased joint spaces could potentially reduce the stiffness in the joints and explain the increase in ABG at 4000 Hz and the drop at 500 Hz. While the average change is small and of minimal clinical relevance, a larger increase of ABG with age is seen in some subjects.

Background: Apert syndrome is one of the craniosynostosis syndromes, with abirth prevalence estimated to be between 9.9 and 15.5/million, and accounts for 4.5 per cent ofcraniosynostoses. Although conductive hearing loss is common in Apert syndrome there are contradicting reports regarding the cause of this hearing loss. There is also no detailed informationavailable on the management of hearing loss in Apert syndrome.Materials and methods: A retrospective analysis of case notes of Apert syndrome patients seen between 1970 and 2003 at Great Ormond Street Children’s Hospital, London, was undertaken.Results: Seventy case notes were obtained. The incidence of congenital hearing impairment was between 3 and 6 per cent. Almost all patients had otitis media with effusion (glue ear), which tended to persist into adult life. More than 56 per cent of cases developed permanent conductive hearing loss by 10–20 years. Repeated grommet insertion was common; even though 35 per cent had trouble with ear discharge and persistent conductive hearing loss. Statistically, grommets made no difference to the risk of developing permanent hearing loss.Conclusion:This study, of the largest number of Apert syndrome cases assembled to date, showed that early optimization of hearing with possible hearing aids needs to be considered. Repeated grommet insertion does not help in optimizing hearing, especially if ear discharge complicates the picture.

Background : Hearing impairment is one of the leading causes of disability in Bangladesh. Since half the cases can be prevented through public awareness, early detection and timely management, planning of public health interventions become necessary. To achieve this, a nationwide level of evidence is required. This survey was conducted with the aim of determining the prevalence of hearing impairment in Bangladesh. Materials and methods : The study was a cross-sectional one, conducted between January to May 2013, where a multistage, geographically clustered sampling approach was used. A total of 52 primary sampling units were selected, and from each unit households were selected at random followed by random selection of an individual from each household. In total, 5,220 people were targeted out of which data collection could be completed from 4260 individuals. (82%). Following clinical assessment of study subjects, hearing status was assessed by pure tone audiometry and otoacoustic emission test. Results : The mean age was 32 years among which 58% were females. Among men, there were 29% students, 28% agriculture workers and 14% business men. A major portion of females (63%) were home makers. On clinical examination, 11.5% respondents had impacted ear wax, 6.2% had chronic middle ear infections with eardrum perforation, and 5.3% had otitis media with effusion.On hearing assessment, 34.6% respondents had some form of hearing loss (>25dB in better ear). Conductive hearing loss was found in 12.0%, sensorineural in 4.5% and mixed in 3.8%, where the latter two increased in prevalence with age. Out of the total respondents, 9.6% had disabling hearing loss according to WHO criteria, with a higher prevalence in adults > 60 years(37%). Logistic regression analysis showed age, socioeconomic status, presence of ear wax, chronic suppurative otitis media, otitis media with effusion and otitis externa were significant predictors of disabling hearing loss. Conclusion : The major causes of conductive hearing loss are chronic suppurative otitis media and otitis media with effusion. Chatt Maa Shi Hosp Med Coll J; Vol.20 (1); January 2021; Page 72-76
