AB-Intra- and Post-Operative Measures of Auditory Function
In Brief
A clinical study evaluating Electrocochleography for Hearing Loss and Cochlear Implant. Completed, enrolled 88 participants across 1 site.
Detailed Summary
The purpose of this study is to see how the inner ear responds to sound delivered to the ear canal during and after your cochlear implant surgery. This information may be helpful in telling us how well a cochlear implant performs after surgery.
Study Details
Timeline
Interventions
Electrocochleography is a noninvasive method of monitoring for acoustic evoked electrophysiologic responses from the cochlea. A speaker in the external auditory canal presents a tone burst stimulus and a nearby electrode, in this case from the apical electrode of the cochlear implant, records changes in the electrical activity within the cochlea. Different functional elements within the cochlea have signature electrophysiologic responses that can be isolated and studied individually. Through the use of intracochlear electrocochleography during cochlear implant electrode insertion valuable insight can be gained about structural or physiological changes that may be occurring.
