Microsurgical treatment of tuberculum sellae meningiomas: Review of 65 cases

Objective To improve the microsurgical techniques for tuberculum sellae meningioma. Methods A series of 65 consecutive patients treated microsurgically were reviewed retrospectively. Results All patients underwent craniotomy with an operating microscope. Complete removal was performed in 61 cases (93 8%). Mortality was 3 1%. It was possible to preserve the olfactory tracts bilaterally or unilaterally in 86%. Most patients showed good visual improvement after operation. Conclusions Use of the operating microscope appeared to increase the total removal rate while lowing the mortality.
