[Treatment Overview] After 40 years of research experience and clinical application at home and abroad, it has been proved that the nociceptive cells of the trigeminal nerve are very sensitive to gamma rays, and the use of a certain dose of rays to irradiate the nociceptive conduction nerve can achieve the purpose of treating pain without damaging the function of the trigeminal nerve, which is the best trigeminal neuralgia treatment option at present. It is the best trigeminal neuralgia treatment option. It has become the preferred method of trigeminal neuralgia treatment in Europe and the United States. Treatment Principle】A large dose of gamma radiation irradiates the nociceptive conduction nerve of the trigeminal nerve root, blocking the nociceptive conduction pathway without affecting the normal nerve sensory and motor functions. Applicable population] applicable to a wide range of people, because gamma knife treatment of trigeminal neuralgia does not require craniotomy, surgery and anesthesia, basically suitable for all patients with trigeminal neuralgia, the following cases are preferred: 1, drug treatment is ineffective in patients with intractable trigeminal neuralgia; 2, receiving other treatment modalities, such as surgery, radiofrequency, closed, acupuncture and other patients who are ineffective or relapse; 3, combined with diabetes, hypertension The treatment features are located in MRI and CT scan, precise blow, once completed, no surgery, no bleeding; facial sensory and motor functions are almost unaffected, and the treatment efficiency is high [Complications and risks] Very few patients have slight facial numbness, sensory abnormalities, etc., which do not require treatment, and patients can gradually heal themselves [Recurrence rate] Not easy to recur. Treatment cost] about 20,000 yuan [treatment time] the actual treatment time of about 20 minutes, does not affect normal life, work. Gamma knife treatment of trigeminal neuralgia need to pay attention to what? 1, the stability of the equipment is very important, must be accurate strike, trigeminal nerve root diameter of only 2-4 mm, imaging can not distinguish between sensory nerve and motor nerve, the treatment site is very close to the brainstem, therefore, the precision of treatment requirements are particularly high, in the past we used domestic gamma knife are to do two targets, to ensure that you can hit. The imported head gamma knife installed in 309 hospital this year, after many times of actual testing and verification, it can be said that it is the most accurate equipment at present. When foreign experts came to guide, they said with great confidence, just one target point can be. However, in all aspects of the treatment, higher requirements are put forward. For example, on the head frame, explicitly require the stability of the cranial nail, than in the past completely based on experience to be more objective, when scanning, no longer only MRI, always add another CT verification, because MRI imaging will have image distortion, in other diseases a millimeter error is acceptable, but in trigeminal neuralgia will seriously affect the efficiency. Some whole body gamma knives, which simply cannot guarantee millimeter accuracy, are completely unsuitable for trigeminal neuralgia treatment. For patients, look carefully, if you choose this gamma knife can also do lung cancer, then you must resolutely give up, such a gamma knife for head diseases, must not be as good as the specialized head gamma knife. 2, gamma knife treatment of trigeminal neuralgia weakness is the relatively slow effect, sometimes a month to a year or so after treatment to see results, during which there should be the appropriate treatment. In the gamma knife treatment at the same time there are local closure, radiofrequency, drugs and surgery and other means to meet the different needs of patients, to relieve the recent symptoms. Recent cases, are a day or two of rapid relief, may be due to the new equipment dose rate caused by high, this because the number of cases is small, further observation is needed. 3. For individual cases of side effects, patients can be arranged to be hospitalized for observation, which avoids accidents and relieves tension. For liver and kidney damage that occurs after long-term drug use, symptomatic treatment is also possible. In the past, our patients were treated as outpatients, but now we ask patients to apply for hospitalization as much as possible, so that the efficacy can be observed at any time and complications can be dealt with in time.
