Four @entity1 and two @entity1 were treated for refractory @entity2686 by gamma knife radiosurgery of the trigeminal nerve root entry zone. The maximum dose of radiation was 70 Gy to the isocenter. Of five @entity1 treated who had refractory chronic @entity2686 and one with refractory episodic @entity2686 , four had relief judged excellent. Of the two remaining @entity1 with refractory chronic @entity2686 , one had relief judged good and the other fair. Five of the six @entity1 treated had relief within a few days to a week following gamma knife radiosurgery. Three with chronic @entity2686 had @entity8168 allowing cessation of all preventive and abortive medication. Although one @entity1 experienced complete relief of chronic @entity2686 , he continued to have @entity2704 requiring medication. None of the @entity1 treated developed significant postradiation side effects during a follow-up period of 8 to 14 months. The authors conclude that gamma knife radiosurgery of the trigeminal nerve affords great promise in the management of chronic and refractory @entity2686 . The technique seemingly carries negligible short- and long- term risk.
