The Continuing Relevance of EABR for Intraoperative Monitoring

The ability to monitor the function of the auditory nerve before, during and after cochlear implant surgery is very important to ensure successful stimulation thereof. All major cochlear implant systems today are equipped with ECAP monitoring capabilities, providing a first order substitute for the more complex monitoring setup with EABR.

However, before we write off EABR as a monitoring technique, it is important to remind ourselves that there will still be instances of complex cases where EABR monitoring is essential and cannot be substituted by ECAP measurements.

One example is the monitoring of the auditory nerve during acoustic neuroma removal prior to implanting a CI. Other complex cases include ANSD etc.

A number of cases studies of different scenarios will be presented and discussed.
