ConclusionĪNSD is a relatively challenging problem for the audiology departments because of its various clinical features and difficulties in management. FM system was given to two cases displaying normal hearing but poor speech discrimination in noisy environments. Rehabilitation was managed by CI and hearing aids in 15 and 23 cases, respectively. Acoustic reflexes were absent in all ears. ABRs were absent/abnormal in 37/3 ears and CMs were detected in all.
The degree of hearing loss was profound in 48% children, severe in 12% children, moderate in 28% children, mild in 10% children and normal in 5% children. The clinical tests revealed that hearing loss greater than 15 dB was present in both ears of 38 cases. ResultsĪNSD was recognized in 74 ears of 40 children (B/U: 34/6) among 1952 children with SNHL (2.04%) detected among 9520 applicants to the department (0.42%). The data were derived from pure tone, OAEs and ABR tests, and further medical risk factors of the subjects were evaluated. This retrospective study included all children younger than 16 years of age who applied to the department between 20 (with the exception of newborn hearing screening NHS referrals). To present our experience on management of the children with ANSD with respect to clinical data.
