Facial myoclonus is a common disease, mainly manifested as paroxysmal involuntary twitching of one side of the face. The incidence of this disease is relatively high, and there are a large number of patients with facial myospasm all over the country, who suffer from the disease and are physically and mentally exhausted, and are eager to get effective treatment as soon as possible to get rid of the disease and resume normal life as soon as possible. For the treatment of facial muscle spasm, most general hospitals in many places adopt conservative medical treatments, such as medication, botulinum toxin treatment, closure treatment, acupuncture treatment and so on. Some patients ask whether methylcobalamin tablets can cure facial muscle spasm. Mecobalamin tablets are a kind of nerve nourishing drug, and most cases of facial muscle spasm are caused by the compression of the facial nerve root by the surrounding blood vessels. In this case, nerve nourishment alone may not be effective. The medication for facial muscle spasm, generally using carbamazepine, phenytoin sodium and other drugs, may have a more obvious effect of relieving symptoms in the early stage of the disease, but the effectiveness of the drug may gradually become worse in the later stages, or even not work. Therefore, most conservative medical treatments can only provide temporary relief but not eradication. The standard treatment for facial spasm is recognized by the medical community as microvascular decompression. The disease can only be cured by surgically removing the vascular compression at the root of the facial nerve. The technique of microvascular decompression is mature and effective, which is recognized and praised by the majority of neurosurgeons and patients with facial muscle spasm. Under what circumstances are methylcobalamin tablets used? It is that after a patient with facial muscle spasm receives microvascular decompression surgery, some doctors may recommend the patient to take some methylcobalamin tablets for nerve nourishing treatment. Of course, because mecobalamin tablets are relatively expensive, in fact, after microvascular decompression surgery, you can also take some b vitamins, like vitamin B1 and vitamin B6, which can also achieve the corresponding nerve-nourishing effect.
