Once facial spasm occurs, it usually does not heal on its own. The discomfort may be relieved with the elimination of certain triggers and after aggressive treatment. Facial myospasm is a vascular neurological disorder, the main cause of which is the compression of the facial nerve root by the surrounding blood vessels, resulting in involuntary twitching of one side of the facial muscles. The onset of facial muscle spasm is paroxysmal and intermittent, and some patients do not have timely treatment during the interval, thinking by fluke that they have cured themselves, but in fact they have not. If not actively treated, it may cause facial expression muscle atrophy, and if the auditory nerve is involved, it may also cause tinnitus, vertigo, and hearing loss. Although facial myospasm does not affect life, it can seriously affect the quality of life and should be seen by a hospital neurologist in a timely manner. Therefore, patients with facial myospasm should be treated as soon as possible and should not be allowed to develop, which can be treated by manifest microvascular decompression.
