How I do it: Endoscopic endonasal resection of the medial wall of the cavernous sinus

Eugenio Cárdenas Ruiz-Valdepeñas et al. Acta Neurochir (Wien). .

Abstract

Background: Resection of the medial wall of the cavernous sinus (MWCSR) is a growing surgical maneuver for the radical removal of pituitary adenomas.

Method: We present a simple modification of the technique following the two dural layers of the floor of the sella turcica, allowing for early identification of the medial wall and simplifying dissection. We support this technique with an anatomical analysis on cadaveric specimens and clarifying dissection images.

Conclusion: Recognition and dissection of the dural unfolding of the floor of the sella turcica are "key points" that lower the risk and facilitate the MWCSR.

Keywords: Anatomy; Medial wall of cavernous sinus; Medial wall resection; Parasellar ligament; Pituitary surgery; Surgical technique.
