Orbital Meningioma
摘要
Orbital meningiomas can be divided into optic nerve sheath meningiomas, sphenoid wing meningiomas with orbital involvement, or primary orbital meningiomas. Orbital meningiomas comprise 34% of all primary brain tumors and 4% of all orbital tumors. Orbital meningiomas can cause proptosis, compression of the optic nerve, contents of the superior orbital fissure, cavernous sinus and the temporal and frontal lobes. The proximity to vital neurological structures makes surgery demanding and challenging. “There is nothing in the whole realm of surgery more gratifying than the successful removal of a meningioma with subsequent perfect functional recovery.” Harvey Cushing, 1922
