Outcomes of endoscopic transsphenoidal pituitary surgery

Since the 1990s, endoscopic transsphenoidal surgery for pituitary adenomas has increased in popularity. Outcomes of endoscopic surgery for clinically secretory adenomas are favorable, and results for nonfunctional tumors reveal high rates of complete resection, improvements in vision, and low rates of complications. This article discusses some of the recent studies reporting outcomes from endoscopic series for Cushing disease, acromegaly, prolactin-secreting tumors, and nonfunctioning macroadenomas.
