Surgical tumor resection is the mainstay of lateral sphenoid wing meningioma treatment, and the goal of surgery is complete removal of the tumor with wide excision of the affected bone and dura, minimizing the risk for future meningioma recurrence.

Pterional craniotomy, flattening of the squamous temporal bone

Limited dural opening into the tumor for initial debulking

Pterional dural opening to access the proximal ICA

Dearterialization of the tumor along the sphenoid wing

Debulking both central and capsular portions of the tumor

Cleaving the tumor along the ICA-M1 MCA to dissect the MCA candelabra

Preservation of the medial arachnoid around the ICA and cranial nerves

Cautery and resection of the dura of the sphenoid wing
