Trigeminal neuralgia was one of the first conditions to be treated with Gamma Knife with better results. The advantages are simple and clear diagnosis, good treatment results, especially compared to open surgery, no risk of anesthesia, bleeding, infection, cerebrospinal fluid leakage; safer. Disadvantages are slower results. Indications for selection: primary trigeminal neuralgia, when drug therapy is ineffective or has obvious side effects, and trigeminal neuralgia that recurs after surgery, gamma knife can be the first choice of treatment. For older, weaker, poorer general condition, unable to tolerate anesthesia, surgery, or patients with high requirements for safety and serious resistance to open surgery, etc., gamma knife treatment can achieve curative results. The radical method of trigeminal neuralgia is gamma knife or craniotomy, the application of gamma knife treatment has been tens of thousands of cases, the vast majority of short-term results are very good. Even bilateral, can also be treated at the same time, for treatment, and then recurrence, can also be treated again, the incidence of comorbidities is low. The advantages of the imported MedicalTech Head Gamma Knife are precision, stability, and the plan system is constantly updated to maintain the most advanced international level. For the treatment of trigeminal neuralgia, MedicalTech’s Gamma Knife is integrated from positioning to planning to all aspects of treatment, and is sure to control the error to sub-millimeter level, thus obtaining more accurate treatment, reducing side effects and achieving more satisfactory results.
