After seeing the word facial spasm, many friends think of the majority of symptoms such as facial twitching, thinking that it is not a big disease, after all, everyone has had eyelid fluttering, the corners of the mouth twitching time is not. It will get better in a few days and there is no need to go to the hospital, thinking that it is a disease that can heal itself. It is wrong to think this way. The facial muscle spasm is a common neurological disorder, most patients are caused by the compression of the nerve root by the blood vessels in the pontocerebellar angle area, some patients are caused by tumors, inflammation or facial neuritis. A very small number of patients are caused by genetic factors, the mechanism of which is not clear, presumably related to genetics. In other words, most of the causes of facial spasm are due to the compression of nerves by blood vessels. It is a progressive disease that will only worsen over time and will not heal on its own. If left untreated, although it is not life-threatening, some patients may suffer from facial muscle paralysis, so do not underestimate facial muscle spasm and seek medical treatment in a timely manner. Microvascular decompression, the only surgical procedure for the complete treatment of facial muscle spasm The most popular surgical treatment is microvascular decompression, which refers to the magnification of the intracranial nerves and vessels through a high-powered microscope, and the spacer is placed between the nerves and vessels, thus relieving the compression of the facial nerve roots and restoring the normal function of the facial nerve. This technique has the advantages of minimally invasive, high safety and low recurrence rate.
