Monitoring of hearing preservation during cochlear implant surgery using stapedial reflex measurement

摘要

A method is described for surgical implantation of a cochlear implant system. An intraoperative baseline value stapedial reflex response is determined for a cochlear implant patient. Then while performing a given step in a multi-step surgical process to implant a cochlear implant system in the patient, the stapedial reflex response is monitored, and if the stapedial reflex response changes from the baseline value response more than a safe change threshold value, the given step is stopped.

主权项

1. A surgical arrangement for implantation of a cochlear implant system, the arrangement comprising:
means for determining an intraoperative baseline value stapedial reflex response for a cochlear implant patient; and means for monitoring a given step in a multi-step surgical process to implant a cochlear implant system in the patient, the means for monitoring being configured to:
a. monitor a stapedial reflex response produced in response to an evoking stimulus, andb. recommend stopping the given step if the stapedial reflex response changes from the baseline value response more than a safe change threshold value.
