Is facial muscle spasm surgery effective? Many patients in the treatment of facial myospasm will collect some treatment methods on the Internet, and search for microvascular decompression for facial myospasm is a good method. After understanding the pathogenesis of facial myospasm, many patients will consider choosing microvascular decompression to treat it. But after all, surgery involving nerves is involved, so is this surgical procedure effective? In the treatment of facial muscle spasm, some patients will choose medication, which is difficult to achieve the purpose of cure, and some patients choose to inject botulinum toxin, not knowing that on the basis of relieving spasm, many patients will have stiff and unnatural expressions, and in serious cases, there will even be serious consequences such as difficulty in closing the eyes and crooked corners of the mouth. The main cause of facial muscle spasm is the abnormal location of blood vessels compressed in the facial nerve out of the brainstem area. Before the cause is removed, i.e., when the ectopic blood vessel leaves the brain stem of the facial nerve, medication and botulinum toxin injection will only “treat the symptoms but not the root cause”, and it is difficult to achieve the root cause. Microvascular decompression is the only way to cure facial muscle spasm in clinical practice, with mature surgical techniques, and the procedure is performed under a microscope with little risk. With the advantages of minimally invasive, high safety and remarkable results, especially the ability to completely preserve vascular and nerve functions, microvascular decompression has quickly been accepted by neurosurgeons around the world and is being promoted worldwide.
