Abstract

Auditory neuropathy spectrum disorder (ANSD) is a neurologic disorder that is present with a variety of characteristics and one of the common management options include hearing aids however, in cases of advanced ANSD with severe to profound hearing loss they would require cochlear implants (CI) for better hearing although the literature is uncommon. Therefore, this study focuses on how CI is an option for children with ANSD. A total of 21 children who are diagnosed to have ANSD and after CI surgery were subjected to aided audiometry with the use of standardized Tamil sentences. Compared to data collected using hearing aids individuals indicate that CI performs lower than hearing aid but with lower consistency which can be attributed to the presence of multiple participants with lower degree of hearing losses. But the present study does shows that use of CI is in fact beneficial in patients of ANSD with severe to profound hearing loss.
