Objective  To explore the microsurgical technique in managing medial sphenoid ridge meningioma.   Methods  The clinical data of 23 cases of medial sphenoidal ridge meningioma were analyzed retrospectively. The main points of microsurgical treatment of medial sphenoid ridge meningioma were discussed.   Results  Of 23 cases of medial sphenoid ridge meningiomas

total removal was made in 15 cases

subtotal removal in 6 cases and partial removal in 2 cases. The microsurgical outcomes were satisfactory in all the patients and no patients died.   Conclusion  The microsurgery via the pterional approach to the medial sphenoid ridge meningiomas can greatly heighten total resection rate of the tumors. Total resection of the tumor depends on its position

character and degree of edema of surrounding tissues. Palliative operations combined with postoperative radiotherapy should be carried out for treating the tumors that can only be subtotally and partially removed.
