Endoscopic Endonasal Transsphenoidal Hypophysectomy: Two Hand Versus Four Hand Technique: Our Experience

An endoscope was used in transsphenoidal surgery and eventually replaced the operating microscope as a tool for visualization. Initially patients underwent operation via a sublabial transseptal approach using a rigid endoscope in conjunction with an operating microscope. The subsequent operations were performed through a nostril using only rigid endoscopes, initially through single nostril by one surgeon (two hands) and later through both nostrils by two surgeons (four surgeons). This is a retrospective study of 96 patients who had pituitary adenomas in last ten years. Postoperatively all patients who had undergone endonasal endoscopic surgery had unobstructed nasal airways with minimal discomfort. More than half of the patients required only an overnight hospitalization.
