What is intraoperative neuropsyiological monitoring?
How did this discipline evolve?
Why is there a need for this clinical specialty?
How does one function in the operating room?
What are potential pitfalls and how does one resolve them?
How does one get trained in intraoperative monitoring?
These are just a few of the questions that arise when the term "intraoperative neuromonitoring" is mentioned. The purpose of this book is to provide satisfactory answers to these questions and more by addressing fundamental issues pertaining to intraoperativemonitoring, in particular within the framework of clinical audiology. The focus is on neural functions that are most likely encountered by audiologists in conjunction with otology/neurotology and head-and-neck surgery operations, such as auditory function and motor cranial nerve function monitoring. While the facial nerve receives the most attention, other cranial nerves are also discussed in conjunction with certain operative procedures. The book includes descriptions of surgical procedures along with the appropriateneuromonitoring protocols. The author’s hope is that the contents of this book will be instructive and that the book will engender sufficient interest and curiosity so that the reader will endeavor to seek additional information about this interesting, growing and clinically effective field. While this book is intended primarily for audiology students and practicing audiologists, its contents will be of assistance and interest to other health care providers seeking information about intraoperative monitoring.
