Transcavernous sinus pituitary gland transposition: how I do it

Abstract

Background: 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.

Method: 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.

Conclusions: Transcavernous sinus pituitary gland transposition is an easily feasible technique and allows gland shifting preserving pituitary function.
