This text, edited by two fellowship-trained rhinologists and two fellowship-trained neurotologists, represents an up-to-date comprehensive resource for any clinician or scientist involved in skull base reconstruction. Each chapter is written by a  super specialist  who has a clinical and/or academic focus in skull base pathologies and reconstruction. The first section is dedicated to basic principles, anatomy, physiology, imaging and anesthetic considerations. The second and third sections discuss pathological processes that lead to cerebrospinal fluid leaks and the need for skull base reconstruction within the anterior and lateral skull base, respectively. The fourth and fifth sections focus on anterior and lateral skull base reconstruction, respectively, with attention to reconstruction techniques and strategies for managing each defect type.
