We describe the case of a 42-yr-old female patient with a 2-yr history of headache that has progressively worsened. Physical examination revealed no neurological deficit. Magnetic resonance imaging showed a large tumor of the left lesser sphenoid wing that enhanced with gadolinium and produced displacement of the midline and the Sylvian fissure. A thorough analysis of the origin of the tumor was done to establish the surgical strategy. With the patient positioned supine with the head slightly turned to the right side, fixed in a 3-pin head clamp, a pterional craniotomy was performed. Since the origin of the tumor is in the lesser wing an early extradural devascularization of the tumor was done with drilling out all the hyperostotic bone of the lesser sphenoid wing, including the lateral base of the anterior clinoid process. Intradural debulking and resection showed the effect of extradural devascularization with an important decrease in bleeding, allowing the total resection of the tumor. An immediate postop magnetic resonance showed a complete removal of the tumor. The patient presented a paresis of the oculomotor nerve that completely resolved in the 3-mo follow-up. In the following video illustration, we narrate this operative case and highlight the nuances of this approach.1 The patient has given assent and written consent for videos, images, or clinical or genetic information to be published.
