LARGE SPHENOID WING MENINGIOMAS INVOLVING THE CAVERNOUS SINUS: CONSERVATIVE SURGICAL STRATEGIES FOR BETTER FUNCTIONAL OUTCOMES

Abstract

On the basis of this study and a review of the literature, we demonstrate that sphenocavernous, clinoidocavernous, and sphenoclinoidocavernous meningiomas of Hirsch Grades 0 and 1 can be excised from the lateral compartment of the cavernous sinus without postoperative mortality and with acceptable rates of morbidity. Residual tumor in the medial compartment (Hirsch Grades 2-4) may be treated with some form of radiation therapy or observation.
