RESUMEN
Twenty four cases of meningioma of the sphenoid ridge were reported. The common symptoms and signs of this tumor were summarized. For practical use, it may be classified as medial and lateral types. The symptoms and signs of these two types are different. Carotid angiograms are helpful to show the blood flow of the tumor. This method cannot be replaced by CT scan. The tumors were removed in fifteen patients totally, among them two died. The authors considered that the most important things for successful operation are to control bleeding carefully, to treat all the blood vessels at the base of the tumor properly and to protect its surrounding important structures during the operation.
