| Description | Between April 1992 and February 1996, 97 patients with skull base meningiomas were treated at our department. The age of these patients ranged from 10 to 80 years. The male/female ratio was 1/2.Fifty-three of these patients had primary open surgery for partial removal or recurrent growth and subsequent radiosurgical treatment. Radiosurgery was performed as a primary treatment in 44 patients. The mean tumor volume was 13.7 $cm^{3}$ (range: 0.8 - $82cm^{3}$). These tumor volumes could be covered by mean isodose volumes of 45% (range: 20 - 70%) and were treated by a mean dose of 13.8 Gy (range: 7 - 25Gy) at the tumor border. Six patients underwent radiosurgery with a staged treatment protocol with 4.6 - 6 months interval. In 78 patients, a total of 102 follow-up scans were available. The remaining 19 patients have not been included in the postradiosurgical evaluation since the observation time was either too short or the patients were lost for follow-up. The mean interval between gamma knife treatment and last follow-up scan was 18.5 months, with a range from 6 to 46 months. Follow-up imaging (CT, MRI or both) revealed a decreased volume of the tumor in 31 cases (40 %). In 44 cases (56%), tumor progression was stopped, and in 3 cases (4%) increased tumor volumes could be observed. In 8 cases marked central tumor necrosis was seen. Neurological follow-up examinations in 76 patients showed a stable neurological status in 71 %, ameliorated status in 24% and worsening in 5% of the patients. |
