Facial myospasm is a vascular-neurological disorder whose main cause is the involuntary twitching of one side of the face due to the compression of the facial nerve root by the surrounding blood vessels. The onset of facial muscle spasm is paroxysmal and intermittent, so many patients get lucky during the interval and think they are well, but they are not. So can facial muscle spasms heal themselves? The answer is no. Once facial muscle spasm occurs, it is generally impossible to heal on its own. If left untreated, it may only get progressively worse. Of course, its attacks may be a wave, sometimes heavy and sometimes light, but in general, it will be more and more serious. If not actively treated, it may also cause atrophy of the facial expression muscles, and if the auditory nerve is involved, it may also cause tinnitus and vertigo. Hearing loss, etc. It is clear that facial spasm, if left to develop, will not affect life, but will seriously affect the quality of life. Therefore, facial myospasm should be actively treated as soon as possible and should not be allowed to develop. Microvascular decompression is currently recognized as the standard treatment for facial myospasm. The vessel compressing the facial nerve root is nudged away, and a Teflon spacer of appropriate size is inserted after confirming that the vessel is sufficiently free from the facial nerve root. If a clear responsible vessel is found intraoperatively, the vessel that may be compressing the nerve is treated and decompression is performed.
