Trigeminal neuralgia occurs in middle-aged and elderly people over 40 years of age, with a female predilection. The clinical manifestations are unexplained, paroxysmal, pins-and-needles, electric shock-like severe pain in the face distributed by the trigeminal nerve, lasting for seconds, minutes or longer. The pain can be spontaneous or caused by irritation of the trigger point by actions such as talking, eating, or washing the face. As the duration of the disease increases, the frequency, duration and pain level of attacks gradually increase, and even wind blowing or loud noises can cause attacks. Since there is no breakthrough in medical research on this disease, it cannot be cured yet, but can only relieve the pain or remove the pain for a period of time. The modern scientific treatment model is “ladder treatment model”, that is, mild patients take conservative treatment methods, such as oral nutritional drugs and drugs such as carbamazepine, local closed treatment; moderate patients use nerve stem blocking treatment, such as temperature-controlled radiofrequency treatment, trigeminal nerve avulsion, anhydrous ethanol injection; severe patients use half-moon ganglion balloon compression method, trigeminal nerve root microvascular decompression, trigeminal nerve root dissection, etc. (such procedures are performed by brain surgeons).
