Trends in Endoscopic and Microscopic Approaches to Transsphenoidal Hypophysectomy in the United States, Using a Global Database Network

Introduction: Microscopic and endoscopic transsphenoidal approaches are the most common approaches to pituitary surgery. Previous studies utilizing US-based databases from 2003 to 2014 have demonstrated early predominance of microscopic approaches (MA), though rates of endoscopic approaches (EA) increased toward 2014. The current study aims to expand on previous studies and describes national trends in approaches to pituitary surgery through 2021 including geographic trends and postoperative outcomes.
