Facial muscle spasm is a very torturous disease in which the patient’s face twitches involuntarily on one side, mostly in paroxysms and irregularly, with varying degrees. A twitch can be as short as a few seconds or as long as ten minutes, with intervals of variable length, and the patient feels distracted and unable to work or study, which seriously affects the patient’s physical and mental health. The treatment of facial spasm is also a problem, especially in many local hospitals, mostly treated with drugs, acupuncture, injections of botulinum toxin and other therapies, but more than ineffective or prone to recurrence. Like drug therapy, also on the carbamazepine can have a certain relief effect on a part of mild patients, long-term eating will also have side effects; and acupuncture, on the contrary, may aggravate the condition; injection of botulinum toxin can temporarily relieve symptoms, but long-term use of drugs may lead to facial paralysis. So these are not the ideal choices, so what is the best treatment for facial muscle spasm? The best treatment for facial muscle spasm is currently recognized by the medical community as microvascular decompression. Microvascular decompression is a procedure that allows the facial nerve roots to be fully relaxed and protected by relieving the vascular compression of the facial nerve roots, thus completely curing the disease of facial myospasm.
