Monitoring auditory and facial nerve integrity during surgical procedures is an activity well within the scope of audiological practice. Intra-operative neurophysiological monitoring was introduced as an experimental procedure in the early 1980s. Within ten years it became standard of care for preservation of hearing and minimizing post-operative cranial nerve deficits. Among the published sources of information on intra-operative neurophysiological monitoring are sections of my New Handbook of Auditory Evoked Responses (e.g., pages 162-170 chapter 5 and pages 424-432 in chapter 6). I've also included here access to a PPT presentation on the topic, from an audiologist's perspective.
