Each transition has been characterized by a conflict between early adopters and skeptics. Eventually, the excessive enthusiasm of the early adopters is tempered by increased experience and evidence-based analysis of outcomes. The most recent example is the dichotomy between external (open) and endonasal (endoscopic) approaches to the skull base. The adoption of endoscopic techniques over the last decade has been primarily driven by endoscopic surgeons (rhinologists and pituitary surgeons) as opposed to oncologic head and neck surgeons (traditional skull base surgeons). This results in a knowledge and skills gap that can only be addressed through greater collaboration and integrated educational programs. Skull base surgery is perhaps unique among the surgical specialties as a true model of interdisciplinary collaboration. The synergy in learning that occurs through collaboration benefits our patients and drives inno- vation across specialties. This volume on skull base surgery is unique in that it achieves equipoise between the competitive and complementary fields of open and endoscopic skull base surgery. We have succeeded in capturing the secrets of expert skull base surgeons from around the world. Overlap in surgical procedures is intentional and provides an opportunity to compare the benefits and limitations of different approaches and techniques. The format of the chapters is designed to provide the essential information in an accessible format. Some of the chapters describe time-tested techniques that every skull base surgeon should master whereas oth- ers are devoted to the latest endoscopic techniques, still in a period of evolution. We are indebted to the authors for investing the time to share their invaluable experience in their own words. We hope that this volume will be the definitive source for skull base surgeons of all types for many years to come. We would be guilty of hubris not to realize, however, that all knowledge is fleeting, especially in a field as dynamic as skull base surgery. Carl H. Snyderman, MD, MBA Paul A.
