Facial muscle spasm is a common neurosurgical disorder, 90% of which is caused by the compression of the facial nerve root by blood vessels. Our left and right facial muscles are controlled by two facial nerves, and both nerves are rarely compressed at the same time, so facial myospasm often develops unilaterally, for example, early on, one side of the eyelid jumps, but after it becomes severe, not only the eyelid jumps, but also the ipsilateral face and corners of the mouth will follow the twitching. Most patients with facial myospasm do not feel pain at the onset of the disease, but only feel bad to look at the problem, and consider it a harmless little thing, the treatment often ends up, in fact, if patients with facial myospasm is not treated for a long time, the prolonged twitching will lead to facial muscle atrophy and deformation, serious hearing, vision, limb and other impairments, the patient’s life and work will gradually cause very serious impact. Medication can reduce the symptoms of facial muscle twitching in some patients. Medication for facial muscle spasm is often used in the early stage of the disease, for those who cannot tolerate surgery or refuse surgery, and as an adjunctive treatment for those whose symptoms cannot be relieved after surgery. For patients with mild clinical symptoms, significant drug efficacy, and no adverse drug reactions, long-term application is possible. Microvascular decompression – the only method for the radical treatment of facial muscle spasm. It is performed under a microscope to return the responsible blood vessel compressing the facial nerve to its original position, decompress the facial nerve, and insert medical spacers to isolate the cerebral blood vessels and the facial nerve. Thus, the purpose of treatment is achieved. Microvascular decompression is a similar minimally invasive procedure that not only can achieve the purpose of treating facial spasm, but also the procedure is safe and reliable, it does not harm any nerve tissue of the patient’s face, it can maintain the integrity of the face and the functionality of the nerve, the efficiency of the procedure is high, and it has become an internationally common method of neurosurgery for the radical treatment of facial spasm.
