Outcome of Auditory Neuropathy Spectrum Disorder after Cochlear Implantation

Purpose: To record language and auditory skills development before and after cochlear implantation (CI) in children with Auditory neuropathy spectrum disorder (ANSD), and to determine the outcome after cochlear implant in patients with ANSD in comparison to patients with sensorineural hearing loss (SNHL).

Materials and methods: Cases Included in this study were divided into two groups. Group I: includes, 13 children diagnosed with ANSD, of them 7 cases were subjected to CI. Group II: includes, 20 cases of SNHL, of them 10 patients were subjected to cochlear implant. For all cases language therapy was given regularly for 6 months pre-operatively and 6 months post-operatively. Auditory Skills Checklist (ASC) and The Arabic language test (receptive, expressive and total language Quotients) were used to monitor the progress concerning auditory skills and language development.

Results: There was significant improvement in SNHL group and ANSD group after cochlear implantation regarding auditory skills (AS) and language development and almost the same outcome was obtained in both groups.

Conclusion: Cases with ANSD improved markedly after cochlear implantation and No differences were noticed in outcome between SNHL & ANSD groups.
