Introduction. Congenital sensorineural hearing loss is one of the most common birth defects with incidence of approximately 1 : 1000 live births. Imaging of cases of congenital sensorineural hearing loss is frequently performed in an attempt to determine the underlying pathology. There is a paucity of literature from India and for this reason we decided to conduct this study in Indian context to evaluate the various cochleovestibular bony and nerve anomalies by HRCT scan of temporal bone and MRI with 3D scan of inner ear in a tertiary care centre.Material and Methods. A total of 280 children with congenital deafness (158 males and 122 females), between January 2002 to June 2013 were included in the study and they were assessed radiologically by HRCT scan of temporal bone and MRI with 3D scan of inner ear.Results. In the present study we found various congenital anomalies of bony labyrinth and vestibulocochlear nerve. Out of 560 inner ears we found 78 anomalous inner ears. Out of these 78 inner ears 57 (73%) had cochlear anomaly, 68 (87.1%) had anomalous vestibule, 44 (56.4%) had abnormal vestibular aqueduct, 24 (30.7%) had anomalous IAC, and 23 (29.4%) had abnormal cochleovestibular nerves.Conclusion. In present study, we found lower incidences of congenital anomalies comparative to existing literature.

<p class="abstract"><strong>Background:</strong> The prevalence of sensorineural hearing loss (SNHL) is 2-3 per 1000 live births in India, and out of 1000 babies, 1 is having profound degree of hearing loss at birth or in the pre-lingual age group. Hearing loss is categorized as syndromic or non-syndromic hearing loss. The present study was done to identify and diagnose children with SNHL and study the etiological profile, so that all necessary timely precautions may be taken as SNHL in pediatric age group affects not only development of speech and language, but also emotional, social and behavioural development.</p><p class="abstract"><strong>Methods:</strong> A cross-sectional observational study was carried out in Department of ENT of a tertiary care centre, in 50 children with congenital SNHL. Data on epidemiological and etiological factors were collected. All cases were analyzed for detailed history and underwent clinical and audiological assessment.  </p><p class="abstract"><strong>Results:</strong> Majority of cases presented between 2 and 4 years of age, however age of detection of congenital deafness by parents was most commonly observed in 6-12 months of age. Out of 50 cases, the maximum number of cases [14 (28%)] were having history of antenatal complications, 11 (22%) cases were having adverse perinatal and postnatal history, while in remaining cases, the etiological factors remained undetermined. In one case associated syndrome was observed (Van der Hoeve’s syndrome).</p><p class="abstract"><strong>Conclusions:</strong> The increased occurrence of etiologies in this study was of prenatal origin, followed by perinatal origin. The present study conducted at a tertiary centre reflects the need of 'High risk' registry maintenance with active surveillance and subsequent screening for early detection of hearing loss.</p><p class="abstract"> </p>

A total of twelve patients with a relatively uncommon form of progressive sensorineural deafness (autoimmune innerear disease) were treated orally with 1 mg/kg azathioprine, once daily, and with 30 mg prednisolone, every other day, for 4 weeks. Statistically significant increases in the ability to hear pure tones or in discrimination on audiometry took place in 10/12 patients. This condition was initially described as ‘sensorineural hearing loss', but it is now clear that the term ‘autoimmune inner-ear disease’ is more appropriate since the vestibular compartment as well as the cochlear compartment is involved. This relatively uncommon disease is one of the few forms of sensorineural deafness that can be successfully treated.
