Bilateral Simultaneous Cochlear Implant in Children and Adults—a Literature Review and Clinical Experience

Abstract

Purpose of review

This paper aims to conduct a literature review and clinical audit on bilateral simultaneous cochlear implant (CI) surgeries in our centre and to assess the hearing and speech outcomes among these patients.

Findings

Bilateral simultaneous cochlear implantation is a safe surgery in our centre with no major or permanent complications. The mean duration of surgery was 3.9 h. All paediatric patients showed increment in Meaningful Auditory Integration Scale (MAIS), Meaningful Use of Speech Scale (MUSS), Listening Progress Profile (LIP) and Parents' Evaluation of Aural/oral performance of Children (PEACH) score even though the rate of improvement varied, with the age at implantation and child's behaviour identified as factors. Post-lingually deafened adult performed well in hearing and speech test post-implantation.

Summary

Bilateral simultaneous CIs is recommended in bilateral profoundly deafened paediatric and adult patients in order to obtain the optimum hearing and speech outcome as evidenced by our clinical experience and literature review. Nevertheless, there are multiple other factors that will affect the outcomes.
