Clinical Utility of Residual Hearing in the Cochlear Implant Ear
Ohio State University
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).
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…
