Performing Intracochlear Electrocochleography During Cochlear Implantation
Published on: March 8, 2022
Evaluation of electrically elicited stapedius reflex threshold measured through three different cochlear implant
Objective:
To evaluate intraoperative electrically elicited stapedius reflex thresholds (ESRTs) measured through three different cochlear implant systems: the Nucleus Mini 22, the Clarion Enhanced Bipolar, and the Med-El Combi-40.
Subjects And Methods:
Relations between intraoperative ESRT and postoperative maximum comfort level (MCL) were examined in seven children (4 Nucleus, 2 Clarion, and 1 Med-El) and one adult (Clarion).
Results:
Preliminary results indicated most ESRTs were either higher or both higher and lower (across the electrode array within a subject) than MCLs. All systems provided satisfactory means for measuring ERSTs.
Conclusion:
It is recommended that hand-held systems have a direct readout to the programming station and that audio and visual feedback be improved for all units.
