The past decade has seen a rapid increase in the application of electrophysiologic measurement techniques in evaluating patients with hearing and balance disorders. Advances in computer technology have generated new and exciting applications in the areas of electrocochleography, electroneuronography, electronystagmography, and the auditory brainstem response. This book examines these recent developments and explores new areas of the field currently under investigation. An important issue in electrocochleography today is the widened AP-SP complex. Contributors to this book evaluate its significance in patients with cerebellopontine angle tumor. The many applications of the auditory brainstem response are surveyed, as well as the current status of the mid- and long-latency evoked responses. An overview of the relatively new area of otoacoustic emissions and its clinical applications is also included. Practicing otolaryngologists, otolaryngology residents, audiologists, audiology students, and auditory and vestibular scientists will benefit most from this well-researched book.
