Facial myoclonus is a common neurosurgical disorder that often occurs in middle-aged and older female groups and has a tendency to become younger in recent years. It is also attracting more and more attention and focus. Many patients have taken aggressive treatment after the disease. Some people choose conservative medications and botulinum toxin injections for treatment, but in the long run these two methods can not treat facial spasm once and for all, but will have an impact on the body’s liver and kidney function, and botulinum toxin injections can not maintain the efficacy for a long time, and need to be re-injected, and with the increase of times people also found that botulinum toxin injections can not maintain the original surgical treatment effect. Microvascular decompression can completely treat facial muscle spasms. This is why they have learned about microvascular decompression, a surgical procedure that can completely treat facial myasthenia gravis. However, they do not know much about this procedure and are afraid to try it because they think it is very risky. In fact, there is no need to worry about this. Microvascular decompression refers to the magnification and reoperation of the intracranial nerve vessels through a high-powered microscope, placing a spacer between the nerve and the vessel, thus relieving the compression of the facial nerve root and restoring the normal function of the facial nerve. 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, and it has become the most effective method for treating facial spasm in the world, which is the only way to completely cure facial spasm. The procedure: 1. Under general anesthesia, a straight incision of 3~5cm is made behind the affected ear, longitudinally at the hairline. 2. After cutting the scalp, a coin-sized bone window is opened in the skull. 3. After entering the pontocerebellar region under the microscope, the facial nerve is carefully explored, and the blood vessels compressing the facial nerve are carefully separated and the spacer is placed between the blood vessels and the nerve. 4. At the end of the procedure, the incision is glued. Therefore, it is said that manifest microvascular decompression surgery for facial spasm does not cause much harm to the body and can be chosen with confidence.
