The skull base is a meeting point for anatomical regions, surgical specialties, and surgical philosophies. Skull base surgery is a dynamic subspecialty and the last decade has witnessed the application of endoscopic techniques to the ventral skull base using an endonasal corridor. The transition from external approaches to an endonasal corridor has not been without controversy. In this volume, we explore the nascent field of neurorhinology, a term that emphasizes the multidisciplinary collaboration between neurosurgeons and rhinologic head and neck surgeons. Authors have applied evidence-based medicine techniques to critically evaluate the literature and attempt to answer some of the most important clinical questions. This second of two volumes focuses on the more complex lesions seen by Otolaryngologists in neurorhinology and includes a discussion of training in neurorhinology.

Topics include: Diseases of the odontoid and craniovertebral junction with management by endoscopic approaches; Cholesterol granuloma of petrous apex; Carotid artery injury following endonasal surgery; Sinonasal malignancy; Endoscopic nasopharyngectomy and its role in managing locally recurrent nasopharyngeal carcinoma; Skull base chordomas; Proton role in chordoma; Functional Outcomes for endoscopic and open skull base surgery: an evidence-based review; Training in Neurorhinology
