What causes facial muscle spasm? Facial myoclonus is a common neurological disorder, most patients are caused by compression of the nerve roots by blood vessels in the pontocerebellar horn region, some patients are caused by tumors, inflammatory diseases 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. Under normal circumstances, the blood vessels and the facial nerve roots are in a parallel relationship that does not compress or interfere with each other. However, as people grow older, blood vessels will gradually thicken, grow and age, and people with high blood pressure are prone to atherosclerosis, resulting in abnormal blood vessel travel and thus compression of the facial nerve root. Long-term compression of the facial nerve root can lead to demyelination, nerve signal conduction disorder, abnormal movement of the innervated facial muscles, resulting in facial twitching symptoms. In addition, lack of sleep, excessive fatigue, emotional tension and mental stress will also aggravate facial twitching. How to treat facial muscle spasm The treatment of facial muscle spasm is generally treated by medication, botulinum toxin and microvascular decompression. Although traditional medication can relieve some of the symptoms of facial muscle spasm, the use of such medication may cause damage to liver and kidney function, and may also be accompanied by the risk of dizziness and drowsiness. The use of botulinum toxin injections to treat facial spasms also has shortcomings. Ninety percent of patients are effectively treated with botulinum toxin for the first time. In addition, botulinum toxin can cause facial muscle atrophy in the long term, so it has a certain impact on the patient’s facial appearance. But these two ways can not cure facial muscle spasm. If you want to cure facial muscle spasm, you can choose microvascular decompression surgery. Microvascular decompression surgery for facial muscle spasm Microvascular decompression surgery refers to the magnification of the intracranial nerve vessels through a high-powered microscope and reoperation, placing a spacer between the nerve and the vessel, thus releasing the compression of the vessel on the root of the facial nerve, restoring the normal function of the facial nerve and relieving the symptoms of facial muscle twitching. This technique has the advantages of minimally invasive, high safety and low recurrence rate, especially it can completely preserve the function of blood vessels and nerves, which has become the most effective method for treating facial muscle spasm in the world, and it is the only way to completely cure facial muscle spasm. Here is a reminder that if you have symptoms in this area do not be anxious, facial muscle spasm is a benign disease, will not endanger the sick, timely hospital visits, it is possible to fully recover.
