The most common method for treating Trigeminal Neuralgia using stereotactic radiosurgery would be with the Gamma Knife approach. Gama Knife radiosurgery involves an aimed focused beam of radiation that concentrates on the area of the trigeminal nerve exiting the brain. This does not require any incision or needle insertion of any kind. Other treatment options using radiosurgery are injections of glycerol, radiofrequency radiosurgery, and balloon microcompression. Microvascular decompression involves an open incision upon the skull.
