Clinical Utility of Residual Hearing in the Cochlear Implant Ear

Status Recruiting

Clinical Trial Summary

The current study is a randomized multi-center clinical trial that investigates the role an intraoperative hearing monitoring system (electrocochleography) has on helping to save residual hearing in patients undergoing cochlear implantation (CI).

Clinical Trial Description

The clinical importance of residual acoustic hearing in CI remains unclear. It is estimated that only five percent of adult candidates undergo CI. A major barrier is the loss of residual hearing associated with surgery, meaning most patients lose any or all residual hearing as a result of the CI surgery, especially since the majority of today's candidates do not suffer from complete deafness. Hence, many candidates are faced with the decision to relinquish their remaining acoustic hearing in exchange for electric hearing via the CI, as CI surgery often results in complete loss of any residual hearing. However, recent developments in hearing monitoring systems during CI surgery have shown promise for providing the surgeon with live feedback of how the cochlear implant insertion process is proceeding, allowing the surgeon to make intraoperative adjustments during the insertion, potentially minimizing any trauma caused by the insertion of the implant, ultimately helping preserve residual hearing. This ultimately could lead to improvements in the rates of hearing preservation. Therefore, the current study seeks to investigate: 1) the advantage of using a hearing monitoring system (electrocochleography) monitoring guided CI surgery on hearing preservation rates, 2) determine the benefit that hearing aid/cochlear implant combined hearing provides participants over non-hearing preservation CI (electric-only stimulation from the CI) on measures of speech perception and quality of life. ;
