Spheno-orbital meningiomas: surgical techniques and results
Abstract Introduction Spheno-orbital meningiomas are characterized by bone invasion with extensive hyperostosis and possible encroachment into the orbit, infra-temporal fossa, and/or the cavernous sinus that render total surgical excision challenging. The surgical technique utilized is a key factor...
