This book covers the scope of cranial nerve monitoring of all cranial nerves that are of practical importance in head, neck, and thyroid surgery. It discussed enhanced patient outcomes in a wide array of surgical procedures in the head and neck that require the maintenance of complex regional functions by protecting cranial nerve integrity. Organized into four parts, the book begins with Part I offering historical perspectives on the subject while simultaneously reviewing various basic and advanced electrophysiology. Part II thoroughly reviews the extra-temporal bone facial nerve (CN VII), Glossopharyngeal Nerve (CN IX), Vagal/Recurrent Laryngeal Nerve (CN X), Spinal Accessory Nerve (CN XI), and Hypoglossal Nerve (CN XII). Subsequent chapters in Part III provide a complete and applied understanding of the neurophysiological principles that facilitate the surgeon’s ability to monitor any nerve and intraoperative neural stimulation and nerve monitoring. The book presents various techniques as the standard of care to provide optimal neural detection, understand the neural functional real-time status during surgery and optimize specific surgical outcomes such as thyroid surgical outcomes. Closing chapters offer essential conversations regarding ethical considerations in nerve monitoring and medical malpractice. Filling a gap in the literature, Intraoperative Cranial Nerve Monitoring in Otolaryngology: Head and Neck Surgery provides a single source for surgeons who wish to optimize their outcomes in patient care and accelerate their learning curve to the level of more experienced surgeons.
