Meningiomas of the tuberculum sella.

A series of 88 consecutive patients operated on for tuberculum sellae meningioma at the Neurosurgery Department of the University of Ankara Medical School was reviewed. Visual impairment was the most common initial complaint. All but 9 patients had visual symptoms. All patients underwent craniotomy, with an operating microscope being used in 62 cases. Use of the operating microscope appeared to increase the total removal rate while lowering the mortality. In our series visual function improved in 53.5%, was unchanged in 27.5%, and worsened in 19% of the patients.
