72 cases with sphenoidal ridge meningioma operated on in recent 12 years in our department were reported. In the microsurgical group and non-microsurgical group, the rate of total removal of medial tumors was 65% and 20% respectively (P < 0.01); lateral tumors was 100% and 77% respectively (P > 0.05); the mortality was 6.7% and 11.9% respectively (P > 0.05); the rate of neurological impaired was 33.3% and 64.3% respectively (P < 0.001); good rate of following up for a long time was 87.5% and 16.7% in medial group respectively (P < 0.05); 66.7% and 75% in lateral group respectively (P > 0.05). It is believed that application of CT and angiography and microsurgical technique is helpful to the diagnosis and treatment of sphenoidal ridge meningioma.
