Cavernous sinus invasion by pituitary adenomas: role of endoscopic endonasal surgery.

Abstract

The endoscopic endonasal inspection is the most effective technique to detect CS invasion. Indeed, it can provide a direct visualization of the medial wall, permitting the assessment of its invasion and the management of those cases with diffuse involvement. We confirm that the revision to the Knosp classification has improved its prognostic role.
