Stereotactic radiosurgery(SRS)performed with Gamma Knife or CyberKnife has been reported to be effective in treating trigeminal neuralgia(TN). Microvascular decompression is the first choice of treatment for patients with trigeminal neuralgia who are difficult to treat with drugs because of its high efficacy, with a pain relief rate of 70%-80% after 5 years. The pain relief rate of TN treated with SRS is approximately 50%-60% after 5 years, which is less than that of MVD. SRS is also inferior to surgery, causing more frequent sensory disturbances in the trigeminal nerve area(6%-20%). However, the serious complications, severe morbidity and mortality, associated with SRS are quite rare. SRS is an extremely minimally invasive treatment that does not require general anesthesia and can be used to treat TN with short-term hospitalization or outpatient visits.
