Cochlear Implantation in Adults With Asymmetric Hearing Loss Clinical Trial

Hearing Loss Clinical Trial

Official title:
Cochlear Implantation in Adults With Asymmetric Hearing Loss Clinical Trial

Clinical Trial Summary

This longitudinal study evaluates the possible benefit of cochlear implantation in the poor ear of adults with asymmetric hearing loss who continue to use a hearing aid in the better hearing ear.

Clinical Trial Description

The study will be conducted as a multicenter, prospective, single-arm clinical trial, evaluating the efficacy and safety of cochlear implantation in patients with asymmetric hearing loss. A repeated-measures analysis will be employed whereby patients will act as their own controls. Participants will be recruited from surgeons and audiologists in Otolaryngology departments at the participating sites. Participants will be evaluated at multiple intervals using a variety of test measures (addressing sound localization, understanding speech in noise, understanding speech in quiet, and quality of life). Prior to receiving a cochlear implant (CI) in the poor hearing ear, participants will be evaluated as follows: - Hearing aid (HA) in the better ear alone - HA in the poor ear alone - Bilateral HAs Participants who have not previously used a poor-ear hearing aid or BiCROS hearing aid will complete a 1-2 week trial and be evaluated at the end of the trial. If performance is better with the alternate therapy (bilateral hearing aids or BiCROS hearing aid) than the better ear alone performance and the participant prefers the alternate therapy, the participant will not continue in the study. Participants who do continue in the study will be evaluated at several post-implant intervals. Post-implant evaluations will occur at 3, 6, 9, and 12 months after initial stimulation of the CI. Participants will be evaluated as follows: - HA in the better ear alone - CI in the poor ear alone - HA and CI together ;
