After 40 years of research experience and clinical application at home and abroad, the nociceptive cells of trigeminal neuralgia are very sensitive to gamma rays, and the use of a certain dose of radiation to irradiate the nociceptive conduction nerve can achieve the purpose of treating pain. Gamma knife treatment of trigeminal neuralgia is very simple, a large dose of gamma radiation irradiation trigeminal nerve root nociceptive conduction nerve, blocking the nociceptive conduction pathway. Gamma knife treatment of trigeminal neuralgia is suitable for a wide range of people, gamma knife treatment of trigeminal neuralgia does not require craniotomy, nor does it require surgery and anesthesia. The following patient conditions are suitable for Gamma Knife treatment: 1, patients with intractable trigeminal neuralgia who have not been treated with drugs; 2, patients who have received other treatments that are ineffective or relapsed; 3, combined with diabetes, hypertension, heart disease and other chronic diseases, elderly patients can be applied Gamma Knife treatment for trigeminal neuralgia treatment features: positioning under MRI, no incision, no blood. Complications and risks of Gamma Knife for trigeminal neuralgia treatment: Gamma Knife is a bloodless procedure that requires no anesthesia or special preparation. While it may appear to be a non-invasive treatment, the potential trauma of Gamma Knife cannot be underestimated. Gamma knife is a radioactive killing treatment, all normal and diseased tissues in the irradiated area, all kill, the greater the irradiation range, the longer the irradiation time, the greater the killing of normal tissues, especially to the vital organs, the blow more; gamma knife in the irradiation or after the irradiation will also cause a series of radiation reactions, such as hair loss, nausea and vomiting, weakness, white blood cells, platelets and even whole blood cell reduction, etc., and in serious cases also cause radiation sickness of treatment difficulties. When also caused by the treatment of difficult radiation disease; gamma radiation will also interfere with and destroy the normal immune function of the human body, which is undoubtedly worse for patients. Some patients by the gamma knife treatment, the pain disappears quickly. But the duration is short, a few months that recurrence, may be related to the immune function is low. Gamma knife treatment of trigeminal neuralgia some patients relapse, can repeat treatment, the treatment cost is generally about 16,000 – 30,000 yuan. The actual treatment time is 20 minutes, without hospitalization, and does not affect normal life and work.
