CLINOIDAL MENINGIOMAS, ALSO referred to as medial or inner sphenoid wing meningiomas, are often difficult and challenging to remove completely and safely, especially when they become large enough to encircle, compress, or displace the adjacent critical neurovascular structures such as the optic nerve, the internal carotid artery and its branches, and the oculomotor nerve. In this article, the authors describe the detailed surgical technique used in their practice in addition to subtle nuances learned from their experience of operating on more than 40 patients with clinoidal meningiomas over the past several years. The primary goals of surgery are to achieve aggressive tumor removal with avoidance of intraciperative morbidity and, in addition, for those with preoperative compromised vision, to provide improvement in their visual function after surgery.
