Facial myoclonus, a serious cranial nerve disorder, is mainly manifested by paroxysmal involuntary twitching of one side of the face. It is very common in clinical practice and has a very high prevalence in the population. There are a large number of patients suffering from facial myospasm all over the country, and they urgently need to be treated effectively as soon as possible. What are the drugs used to treat facial spasm? There may be some local general primary hospitals use western drugs such as carbamazepine or phenytoin sodium for the treatment of facial spasm, which may be able to play a temporary role in relieving the symptoms for some patients with mild disease or patients in the early stage of the disease, but the effect is not good in the later stages, and the effect of the drug gradually weakened. There are also significant side effects of taking this western medicine, including damage to liver and kidney functions, and harm to the digestive system. Some doctors also use Botox injections to treat facial muscle spasms. In fact, botulinum toxin only temporarily blocks the nerve, which may temporarily relieve the symptoms, but it will come back after a short month or two to three months. Repeated injections of Botox can also have significant side effects and may lead to serious consequences such as facial paralysis. Therefore, medication is not the ideal solution for facial spasm. Medical research shows that the cause of facial spasm is mainly the compression of the facial nerve root by the surrounding blood vessels. Then the treatment of area spasm should start from this cause. At present, manifest microvascular decompression is a very effective means of treating facial muscle spasm. This is a minimally invasive surgery that can release this vascular compression of the facial nerve roots, so that the facial nerve roots can be released and the nerve function can be normalized, and the twitching symptoms of the face can be relieved with excellent results.
