Postural Change Assists Surgical Maneuverability During Endoscopic Transsphenoidal Surgery for Pituitary Macroadenoma.

Abstract

In endoscopic transsphenoidal surgery for pituitary adenoma with suprasellar extension, the prolapse of the stretched floppy diaphragma sellae can obstruct the surgical corridor, posing challenges during pituitary surgery. We introduce a simple postural change technique to mitigate this issue and share our clinical experience. Pituitary surgery is performed on an operating table where the patient's position can be adjusted. During transsphenoidal pituitary surgery, raising the patient's head to a Fowler position causes the diaphragma sellae to move upward, whereas lowering the head to a supine position causes it to descend. This simple adjustment minimizes hindrance from the floppy diaphragma sellae during surgery. We illustrate this technique in pituitary surgery, where diaphragm sellae relocation is necessary. A simple postural change technique effectively manages prolapsed floppy diaphragma sellae, enhancing visualization and surgical accessibility during endoscopic transsphenoidal pituitary surgery.
