Facial myospasm is a relatively common clinical condition, with early symptoms manifesting as eyelid fluttering, and later sometimes involving the perioral region and even neck muscle spasm in some patients. Idiopathic facial muscle spasm is more common in life, and the cause is mainly the compression of the facial nerve root (facial nerve out of the brainstem area) by the surrounding blood vessels. It is known that prolonged twitching of facial muscles can cause small eyelids, facial atrophy, headache, loss of vision, tinnitus, etc. So, who needs to pay more attention to this disease of irregular twitching of facial muscles, in other words, which group of people are prone to get facial myospasm? Medical research has found that the main onset of facial muscle spasm is concentrated in middle-aged people around 40 years old, because once people get older, blood vessels will become thicker and older, and it is easy to form arteriosclerosis, which causes compression of the facial nerve root and causes facial muscle twitching. From the clinical disease data, there are more women than men. If facial muscle spasm does not take effective treatment to relieve the symptoms, it will not heal on its own, and the condition will worsen day by day, and develop to severe severity to seriously affect life and work. Microvascular decompression is a safe and minimally invasive procedure, and is also a more effective procedure for treating facial muscle spasm. The advantage of this procedure is that it is technically mature, easy to operate, effective, and safe without damaging nerves and blood vessels.
