Trigeminal nerve injuries present complex clinical challenges and can be very distressing for patients, resulting in abnormal sensations of the oro-facial region, yet surgeons may lack the knowledge required for optimal patient management based upon the specific nerve injury. This textbook is the first to be devoted to the diagnosis and management of trigeminal nerve injuries. A wide range of topics are covered, including historical perspectives, demographics, etiology, anatomy and physiology, pathophysiology, clinical neurosensory testing, nonsurgical management, and surgical management and principles of microneurosurgery, specifically involving the inferior alveolar and lingual nerves. Algorithms and a glossary are provided that will assist in the clinical management of these complex scenarios. The authors include surgeons with considerable experience and expertise in the field who have previously published on the subject. This book will serve as an ideal clinical reference for surgeons with patients who sustain trigeminal nerve injuries.
