In principle, primary trigeminal neuralgia is often treated with drugs, radiofrequency temperature-controlled thermocoagulation of the semilunar ganglion, closure and microvascular decompression, etc. However, secondary trigeminal neuralgia should be treated according to the cause of the disease. 1. Drug treatment: the efficacy of primary trigeminal neuralgia is very good, but the efficacy of secondary trigeminal neuralgia is not exact. Primary trigeminal neuralgia is often treated with carbamazepine, phenytoin sodium, gabapentin, etc. Secondary trigeminal neuralgia is often treated with carbamazepine and phenytoin sodium to relieve the pain, and the treatment should be tailored to the cause of the disease. 2. Surgical treatment (1) Microvascular decompression surgery: it refers to pushing away the blood vessels that cause pressure on the trigeminal nerve under the operation microscope, so as to relieve the pressure of blood vessels on the trigeminal nerve, thus relieving the clinical symptoms. (2) Transcutaneous semilunar ganglion radiofrequency electrocoagulation therapy: radiofrequency needles are percutaneously inserted into the trigeminal ganglion under the guidance of X-rays and CT, selectively destroying the nerves that conduct pain and warmth sensation, so as to achieve the pain-relieving effect. 3. Closure therapy: The trigeminal nerve branches or ganglia are closed by injecting anhydrous ethanol or glycerin to destroy the sensory nerve cells to stop pain. When patients are diagnosed with trigeminal neuralgia, they should consult a doctor in time and choose the appropriate treatment plan under the guidance of a physician, and do not blindly use medication on their own.
