Background
Notes on this case’s cranial location, pathology and surgical approach, with published sources. General education only, not advice for any individual patient.
Cranial Location
Medial Sphenoid Wing
The sphenoid wing forms the boundary between the anterior and middle fossae; its medial third abuts the anterior clinoid, optic nerve, cavernous sinus and internal carotid artery. Medial (clinoidal) sphenoid-wing meningiomas encase these structures and threaten vision.
Anterior clinoidectomy and optic-canal unroofing, usually through a pterional or orbitozygomatic route, are central to safe resection of these challenging skull-base tumours.
