Facial muscle spasm is a facial nerve disease that does not bring physical pain to the patient, so people do not pay attention to this disease, however, people do not know that facial muscle spasm, if not treated effectively, often leads to restlessness, irritability, irritability, insomnia, and even facial muscle atrophy. One side of the face is big and the other side is small, making one’s facial problems more serious, thus affecting life, work and study. If left untreated, a vicious circle will be formed to harm the patient’s body. The onset of facial muscle spasm mostly starts from the orbicularis oculi, with intermittent involuntary spasms or convulsions, gradually expanding to the lower part of the face, affecting the orbicularis oris and other facial muscles, especially the orbicularis oris muscle spasm is most easily noticed, lasting from a few seconds to a few minutes. In severe cases, the symptoms of facial muscle spasm include facial narrowing, smaller eye fissures, deepening of the nasolabial fold, and distortion of the mouth to the diseased side. It can be exacerbated by stress, emotional stress, fatigue, and voluntary movement and cannot be controlled on its own. Some patients with symptoms of facial myoclonus keep having seizures all day long, affecting speech, etc., which can cause facial muscle atrophy over time. Therefore, facial myospasm should be treated as early as possible to avoid irreversible consequences. The most effective treatment for facial muscle spasm is surgery, surgery for facial muscle spasm, the development of microvascular decompression surgery treatment, this surgery is for the cause of facial muscle spasm treatment, surgery effect is remarkable. Through this treatment, more than 30,000 patients have been operated on, and the twitching symptoms of the operated patients have disappeared immediately, which has been well received by the patients. Microvascular decompression is the only treatment that targets the cause of facial muscle spasm and preserves the anatomical integrity of the facial nerve. Because of its obvious effect, non-destructive nature, low side effects, and extremely low recurrence rate, microvascular decompression is currently the safest and most effective method internationally recognized for the treatment of facial muscle spasm.
