1.0 Introduction
Transsphenoidal pituitary surgery has continued to evolve since being first described in the early 20th century. Initially with a headlight and speculum , to using a microscope, to now most commonly performed entirely endoscopically. In 1992, Jankowski et al described an entirely endoscopic transnasal approach to the pituitary . This is currently the most common endoscopic transsphenoidal technique for pituitary surgery and involves a direct transostial approach with a posterior septectomy . However, a technique via an endoscopic transseptal route has also been described which avoids a posterior septectomy but comes with its own disadvantages . We describe a modification of the endoscopic transseptal technique, and discuss its pros and cons.
