Facial muscle spasm is a neurological disorder that develops without warning, but once it is diagnosed, it needs to be treated with surgery. The cause of facial muscle spasm is the compression of the facial nerve by blood vessels, which causes the facial muscles innervated by the facial nerve to twitch uncontrollably. However, many patients do not have a good understanding of the treatment and surgery for facial muscle spasm, and some patients have asked how long it takes to fully recover from facial muscle spasm surgery. Microvascular decompression surgery is the most thorough and effective way to treat facial muscle spasm, and is also recognized by the medical community as the only way to cure facial muscle spasm. During the surgery, the pressure points of blood vessels and facial nerve are found, the responsible blood vessels that are compressing the facial nerve are returned to their original positions, and medical pads made of special materials are inserted to protect the facial nerve from further compression, so as to achieve the purpose of eradicating the disease. The surgery requires precise medical technology, minimizes trauma to the patient, and the recovery is relatively fast, about a week or so after the surgery. If there are no special circumstances after the operation, there is no need for regular review. Although facial muscle spasm itself has nothing to do with diet, for better wound healing, it is recommended to maintain balanced nutrition and avoid spicy, greasy and stimulating foods for one month after surgery.
