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
