Prognostic factors for radiosurgery treatment of trigeminal neuralgia.

Objective: Trigeminal neuralgia treatment results are thought to be highly dependent upon selection criteria. We retrospectively analyzed a series of patients to determine the likelihood of treatment success for patients treated with radiosurgery.

Methods: A retrospective analysis of 82 patients treated with linear accelerator radiosurgery was undertaken with a median follow-up period of 18 months.

Geometrical accuracy of the Novalis stereotactic radiosurgery system for trigeminal neuralgia.

Object: Stringent geometrical accuracy and precision are required in the stereotactic radiosurgical treatment of patients. Accurate targeting is especially important when treating a patient in a single fraction of a very high radiation dose (90 Gy) to a small target such as that used in the treatment of trigeminal neuralgia (3 to 4-mm diameter). The purpose of this study was to determine the inaccuracies in each step of the procedure including imaging, fusion, treatment planning, and finally the treatment.

Treatment of trigeminal neuralgia with linear accelerator radiosurgery: initial results.

Object: Radiosurgery has emerged as an important treatment of trigeminal neuralgia. Substantial advantages have been demonstrated in safety and comfort over other modalities. Radiosurgical treatment of trigeminal neuralgia has been well investigated with gamma knife devices involving fixed cobalt sources.
