Facial myoclonus is a common cranial nerve disorder, which mainly manifests as paroxysmal involuntary twitching on one side of the face. The degree of twitching varies, the twitching is mild at the beginning of the disease, but as the disease develops, the scope of twitching gradually expands, from the initial eyelid fluttering to the twitching of the corners of the mouth and nose, or even to the twitching of the whole half of the face or even the more serious twitching of the neck muscles, the degree of twitching also gradually increases, the frequency of seizures gradually increases, and the duration of each twitch may also be gradually extended, from a few seconds to several minutes. may reach several minutes. This is a great pain for patients, seriously affecting their normal life, work and study, so once the upper muscle spasm, should receive regular and effective treatment as soon as possible. For the treatment of facial muscle spasm, most ordinary local primary hospitals are not good at it, they often take conservative medical treatment methods, such as taking drugs, acupuncture, closed-loop injections, botulinum toxin injections, etc., but these can not really solve the problem, often only briefly alleviate the symptoms of twitching, and later will still recur, but also often have a lot of side effects, causing more damage to the body, so Internal conservative methods are not ideal for the treatment of facial muscle spasm. The current standard method recognized by the medical community for the treatment of facial myasthenia is microvascular decompression, which is a minimally invasive procedure to relieve the cause of the disease by relieving the vascular compression of the facial nerve root, thus achieving a good treatment effect. Some patients ask what to do if the facial spasm recurs. Microvascular decompression is a kind of eradication treatment for the cause of facial muscle spasm, relieving the vascular nerve compression, fully relaxing the facial nerve, and restoring the normal function of the facial nerve. The effect of the surgery is remarkable and exact, and usually there is no recurrence, and the recurrence rate is extremely low. For those patients with a very low probability of recurrence, they can still be treated with surgery again at a later stage.
