Purpose: Transsphenoidal pituitary surgery can be carried out with either an operating microscope or with an endoscope, but the relative frequency of both techniques is unknown. Methods: All microscopic and endoscopic transsphenoidal pituitary surgeries were extracted from the Centers for Medicare and Medicaid Services Part B data files between the years 2003 and 2013. National and state-level trends were compared over time. Results: Endoscopic surgery significantly increased and microscopic surgery significantly decreased over the years 2003–2013. Thirty-eight of 48 states increased their use of endoscopic surgery, while 38 of 48 states decreased their use of microscopic surgery. Conclusions: Nationwide data show a clear trend for an increasing use of endoscopic transsphenoidal surgery at the expense of microscopic surgery. The underlying causes of these trends are unknown, but clearly deserve further investigation.
