Patient: Description of condition (time of onset, main symptoms, hospital visited, etc.): trigeminal nerve, pain for about 3 years, has been treated conservatively with medication with poor results. The pain increases when the weather changes and prevents eating and sleeping. Had been treated with medication at Wuhan Stomatological Hospital with poor results. Wanted to have surgery, but the risk of open surgery is too high, and the recurrence rate of Gamma knife surgery seems to be high. I need the latest radiofrequency thermal coagulation surgical treatment, I do not know if your hospital has this surgical method. I hope to give a reply soon, I am grateful. Doctor: drug treatment does not work for trigeminal neuralgia now the first treatment option is microvascular decompression surgery, the efficacy is very accurate, in principle, can cure this intractable pain; followed by gamma knife treatment, its characteristics are truly non-invasive treatment, no pain; radiofrequency treatment has nearly 30 years of history, its treatment effect is slightly better than the traditional closed treatment, the recurrence rate is more obvious than the first two, also need anesthesia has a certain trauma. Our hospital carries out this technology, but not as a priority recommended treatment method.
