Facial spasm, in its literal sense, is actually well understood as a state of spasm in which the muscles of the human face occur without regular twitching. As a common neurological disorder of the brain in middle-aged and elderly people, it mostly starts from the eyelids and gradually spreads to other muscles of the face. Although facial spasm is not potentially life-threatening, it can have a significant impact on a person’s life, work and social life, and can easily lead to low self-esteem and depression. Facial muscle spasm etiology Long-term clinical practice shows that the pathogenesis of facial muscle spasm has a great relationship with the facial nerve and blood vessels, about 80%-90% of patients in the clinic are due to the facial nerve root of the brain by the vascular extrusion, stimulation, causing neuropathy, the appearance of facial muscle involuntary twitching. This significant discovery has not only given experts a deeper understanding of facial muscle spasms, but also opened a new door for its treatment. The cause of the disease was removed through surgery and satisfactory treatment results were achieved. The procedure for facial muscle spasm The procedure for treating facial muscle spasm is called microvascular decompression, which not only overcomes the limitations of traditional methods in the treatment of facial muscle spasm, but also does not damage the facial nerve and is very effective. Under general anesthesia, a 3-5 cm longitudinal incision is made behind the affected ear and within the hairline, and a coin-sized bone window is opened in the skull. The surgery is completed with glue. The surgery time for facial spasm is usually related to the degree of adhesions of the vessels and facial nerve and the surgeon’s proficiency.
