Facial muscle spasm is a common facial disease, mainly manifested as involuntary twitching of unilateral facial muscles, most of the patients with facial muscle spasm due to the onset of no pain sensation, think it is a harmless little thing, and often let it go, but patients with facial muscle spasm need to know that if the long-term untreated not only will be the facial nerve damage and facial paralysis phenomenon, but also lead to psychological disorders, which will cause a lot of harm to the patient’s daily life and work. This will cause great harm to the patient’s daily life and work. Therefore, it is recommended that patients suffering from facial muscle spasm should be treated as soon as possible, and many patients often choose medication in the early stage of the disease. Some patients may ask how carbamazepine works in treating facial muscle spasms. Carbamazepine is a kind of drug that can slow down the speed of all cells transmitting nerve electrical signals, so it can slow down the speed of nerve electrical signals transmitted to the muscles, as well as muscle twitching conduction to the sensory center of the brain. This can slow down the frequency of facial throbbing, but the drug can not change the fact that the facial nerve is compressed, so for facial muscle spasm, drug treatment can not be eradicated, only temporary relief of some minor symptoms. And need to take drugs for a long time, and long-term medication has serious side effects. The body will also produce drug resistance, and then the drug treatment is almost ineffective. However, patients with facial muscle spasm can be cured by adopting cause-specific treatment. Patients can use microvascular decompression surgery to separate the facial nerve from the place where it is compressed by blood vessels, so as to maintain normal nerve function. The procedure is relatively low-risk, has clear results, and is widely recognized by patients.
