Endoscopic transnasal transseptal pituitary surgery

Abstract

Pituitary surgery is performed via a transsphenoidal approach in the vast majority of cases according to various methods that have changed over the years. A microscopic transseptal approach via a sublabial mucosal incision or a nasal mucosal incision has also been extensively used. An endoscopic transnasal approach was first described in the 1990's, followed by the concept of a microscopic transseptal approach and an endoscopic strictly endonasal approach. We use an entirely endoscopic transseptal transsphenoidal approach via an incision in the nasal mucosa for both access and tumour resection. This procedure has a number of advantages: strictly midline approach to the sella turcica, large operative field, no interference between instruments and a low rate of nasal complications.
