Introduction: Fully endoscopic endonasal surgery (fEES) has evolved to the point of becoming one of the preferred methods of treatment for many sellar region pathologies. The development of better technologies and improved results has led to the widespread adoption of these methods around the world. Although there is a learning curve associated with these types of procedures, they have proved to be extremely useful as part of the neurosurgical armamentarium. The purpose of this study was to retrospectively evaluate perioperative morbidity and mortality as measures of surgical outcomes in a single institution after the adoption of fEES.
