Background: Trigeminal neuralgia is a debilitating condition caused by compression of the trigeminal nerve, ganglions, or divisions. Gamma knife radiosurgery has been increasingly used in the treatment of trigeminal neuralgia as a non-invasive alternative to microvascular decompression and rhizotomies.
Methods: We reviewed the medical literature regarding outcomes, time course, and prognostic factors for successful pain control in gamma knife radiosurgery. The dosimetry, target, complications of treatment, as well as perceived quality of life in treatment were also reviewed.
Results and conclusion: The growing body of literature suggests that the low rates of complications of gamma knife radiosurgery, coupled with the high success rates and patient satisfaction, allow it to be increasingly used as primary intervention for trigeminal neuralgia for appropriate patients.
