Usefulness of MRI and EABR Testing for Predicting CI Outcomes Immediately After Cochlear Implantation in Cases With Cochlear Nerve Deficiency

Abstract

Objective: Cochlear nerve deficiency (CND) is often associated with poor cochlear implant (CI) outcomes, and patients with CND may be candidates for auditory brainstem implantation (ABI). The purpose of this study was to identify investigations which predict CI outcomes immediately after cochlear implantation to recommend ABI within the critical period of auditory development when cochlear implantation precedes ABI. Study Design: Retrospective case review. Setting: Cochlear implant centers at tertiary referral hospitals. Patients: Nineteen children with CND who underwent cochlear implantation and intraoperative electrically evoked auditory brainstem response (EABR) testing. Interventions: Di..
