Transcavernous sinus pituitary gland transposition: how I do it.

Abstract

Pituitary transposition preserving gland function is possible when approaching superior clival region tumors. Clinical experience along with detailed anatomical knowledge makes this technique safe and effective. We present a step by step description of our technique based on the most recent anatomical references to get a pituitary transposition through the different compartments of the cavernous sinus. By this technique, we achieve minor gland manipulation and a better surgical view of this area. We support this technique with an anatomical analysis on cadaveric specimens and clarifying dissection images. Transcavernous sinus pituitary gland transposition is an easily feasible technique and allows gland shifting preserving pituitary function.
