Meningiomas constituted 12.9% of our verified intracranial tumor series. Headaches and seizures were the most common symptoms. The most accurate diagnostic confirmatory test was ventriculography (93%). Total removal was thought to have been accomplished in 85%, but 10% of these later had recurrences. The most common site for incomplete removal and recurrence was sphenoidal ridge. Parasagittal and convexity tumors are generally removed by enlarging a bur hole to make the craniectomy opening correspond to the site and size of the tumor. The 30-year postoperative case mortality in this series was 14.8%; the postoperative case mortality in the last ten years was 8.5%. Seventy-four (57.8%) of the 128 patients were able to return to gainful employment. Seventy-five percent of the patients surviving surgery were alive five years after operation.
