Abstract

|
|
Background : Meningiomas originating from the sphenoid ridge are surgical challenge because of adjacent cranial nerve, carotid artery, its branches, and cavernous sinus. We removed 5 large tumors of sphenoid ridge with skull base approach and are going to report out technique and experience.
Methods : Five patients were operated between January, 1997 and December, 2001. The age of the patients were from 36 to 56. There are two men and three women. All tumors were approached through orbitozygomatic or transzygomatic technique. At first, feeding arteries were interrupted and skull base bone attached to tumor was drilled out and then intradural tumor was removed.
Results : Four of five tumors were completely removed and one was gross totally removed due to infiltration of middle cerebral artery. A case of transient hemiparesis was occurred because of vasospasm of a branch of middle cerebral artery and transient oculomotor palsy was observed in a patient whose tumor invaded the cavernous sinus.
Conclusion : We successfully treated surgically challenging large sphenoid ridge meningioma with skull base technique. This approach may play an important role in the treatment of large vascular sphenoid ridge tumors.
