Hearing Preservation Cochlear Implantation: a Review of Audiologic Benefits, Surgical Success Rates, and Variables That Impact Success

Abstract

Purpose of Review

The objectives of this review are as follows: (1) examine the audiologic benefits of hearing preservation, (2) review rates of successful hearing preservation, and (3) analyze variables that impact hearing preservation success.

Recent Findings

Hearing preservation has been shown to confer the following audiologic benefits: better speech understanding in complex listening environments, superior sound localization, and improved music appreciation. There is a notable lack of standardized criteria for reporting of hearing preservation outcomes—this leads to considerable heterogeneity across studies. Rates of functional (i.e., aidable) hearing preservation generally range between 50 and 90%. Studies demonstrate higher preservation rates and more durable hearing outcomes with shorter, straight electrode arrays.

Summary

With advances in CI technology and surgical techniques, residual hearing can be preserved after CI surgery in the majority of patients. Cochlear implant recipients with preserved hearing demonstrate better speech understanding, sound localization, and improved music appreciation.
