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.
