We may sometimes see people around us with frequent facial twitching or involuntary eyelid fluttering, which is likely to be suffering from a cranial nerve disease called facial myoclonus. Facial myospasm is a very common clinical disease with a very high prevalence in the population, and there are a large number of patients with facial myospasm in the country, who are suffering from great pain and great psychological and mental pressure at all times, and urgently need timely and effective treatment to relieve the pain and restore a healthy life. How can facial spasm be treated? In fact, these conservative methods, such as drugs, acupuncture, closure, botulinum toxin injection, etc., do not really solve the problem and the treatment effect is not ideal. To really cure facial muscle spasm, you should start with its causes. Medical research shows that the main cause of facial muscle spasm is the compression of the facial nerve root by the surrounding blood vessels. This disease occurs mostly in the middle-aged and elderly population, and is more common in women. The aging of blood vessels in this group, coupled with underlying diseases such as hypertension, hyperlipidemia, and hyperglycemia, can easily cause atherosclerosis and abnormalities in the travel of blood vessels. As a result, adhesions and compressions may occur between the blood vessels and nerves around the facial nerve roots, which may disrupt the nerve signal transmission and cause facial twitching symptoms. Therefore, the breakthrough point in the treatment of this disease is how to release the vascular compression of the facial nerve root. At present, microvascular decompression is recognized as the standard treatment for facial spasm. Microvascular decompression is a surgical procedure to investigate the anatomical relationship of the blood vessels around the facial nerve root to relieve the compression of the nerve, thus curing the disease with excellent clinical results.
