title: Evaluation of electrically elicited stapedius reflex threshold measured through three different cochlear implant systems.
abstract: 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.
  
  
  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.
  
  
  CONCLUSIONS
  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.
