Surgery of Tuberculum Sellae Meningioma: A Technical Purview on Pterional Approach

Amidst the raging debate between transnasal and transcranial approaches, the critical factor that dictates success lies in the meticulous dissection of the tumor from the optic apparatus, anterior communicating artery complex, and the pituitary stalk. In this surgical video, we describe the resection of a tuberculum sellae meningioma through the pterional approach highlighting dissection through the appropriate arachnoidal plane.

Case Description

The patient is a 75-year-old female who presented with optic nerve compression with bitemporal hemianopia and endocrine function abnormalities. A transcranial approach was done to effectively decompress the optic nerve. The video includes a detailed discussion on the surgical techniques including working between the different surgical corridors, working in the arachnoid plane to dissect the neurovascular structures away from the tumor, identification, and preservation of pituitary stalk. Postoperatively, the patient's visual field deficit improved with a remaining isolated right temporal field defect at 2 months follow-up. Her endocrine function improved after the surgery.


In the era of endoscopic surgery, transcranial approaches for suprasellar tumors like tuberculum sellae meningiomas still have a distinct surgical role. Our discussion extends to reiterate the strengths and weaknesses of the transcranial approach to this region as compared with the endoscopic approach. We believe decompression of optic nerves, separation of Acom complex from the tumor, and preservation of pituitary stalk are better achieved through a transcranial approach.
