Microsurgical treatment of sphenoid ridge meningiomas via pterion approach

Objective: To sum up the experience of treating sphenoid ridge meningiomas by microsurgery via pterional approach.Methods: Sixteen cases of sphenoid ridge meningiomas were analyzed retrospectively.The surgery was performed via pterion approach.Six of the cases were of medial type tumor,4 cases middle type tumor and 6 cases lateral type tumor.Results: The tumors were totally resented in 13 cases,subtotally resented in 2 cases and partially in 1 cases.One of them died and 1 had hemiplegia.Conclusions: Pterion approach plus micromanipulation and proper preservation of vital vessel and nerves can improve the removal rate of sphenoid ridge meningioma and reduce postoperative nervous malfunction.
