Facial muscle spasm is a common functional neurosurgical disorder. Facial muscle spasm can manifest as primary or secondary. Primary facial myospasm can generally occur at rest, and the spasm is relieved after a few minutes and is not controlled; facial myospasm produced by the sequelae of facial palsy is only produced when doing actions such as blinking and raising eyebrows. Primary facial myospasm is more common in clinical practice and is more likely to occur in middle-aged and elderly people. What are the risks associated with facial myospasm?

The procedure is performed under general anesthesia with high safety and significant results.
