Trigeminal neuralgia is a transient, recurrent paroxysmal severe pain in the distribution of the facial trigeminal nerve. It is manifested as a burning, stabbing, cutting or tearing pain in the affected face. Each attack may last from a few seconds to 1-2 minutes and then stop abruptly, with intervals as normal. The condition may gradually worsen and the number of pain attacks may become more frequent, even once a few minutes, resulting in more than one day. The pain can be triggered by touching the skin of the patient’s face. In severe cases, patients dare not wash their faces, brush their teeth or even chew, and rely on drinking a small amount of liquid or semi-liquid food to maintain nutrition throughout the day, which seriously affects the quality of life. There are two main treatment options: 1, radiofrequency treatment: safe surgery, low complication rate and mortality, the elderly and frail people can also be performed, easy to operate, eliminate the pain, the sense of touch most of the existence. Low cost and can be treated again after recurrence. The side effects of drugs are avoided. The first branch of the trigeminal nerve is treated by radiofrequency thermal coagulation in the supraorbital approach, the second branch in the infraorbital nerve, and the third branch in the lateral approach. 2, trigeminal nerve root apparent microvascular decompression, the pain disappeared after surgery accounted for more than 90%. It has the advantages of high cure rate, short operation time, fast postoperative recovery, small incision and almost no damage to the patient’s nerve and brain tissue. Facial muscle spasm is an involuntary clonic twitching of one side of the face. At present, microvascular decompression is the only way to cure this disease, which has the advantages of high cure rate, short operation time, quick postoperative recovery, small incision, and almost no damage to the patient’s nerve and brain tissue.
