Abstract
The paradigm of skull base surgery has drastically changed over the last couple of years. Specifically, fractionated stereotactic radiotherapy has become more popular as a technique that allows control of skull base tumors with minimal morbidity. We discuss our experience with the use of an intensity modulated fractionated stereotactic radiotherapy system. We treated 30 patients over a 12-month period. Patients' pathology included meningiomas, pituitary tumor, acoustic tumors, and head and neck tumors. Volume of the lesions varied from 7 to 70 cc. Number of fractions varied from 2 to 33. Total delivered dose ranged from 15 to 64 Gy. In all patients the conformality index was ≤ 2.5 and the homogeneity index was < 2.
