Facial spasm, is a common neurological disorder in life. The initial manifestation of the disease is usually eyelid twitching, and patients rarely notice its harmful effects. Over time, the condition worsens and the twitching spreads to one side of the face. Bilateral lateral myasthenia gravis is extremely rare, with an incidence of 1 in 100,000. What is the treatment for bilateral facial myasthenia in the unfortunate event that it occurs? The cause of facial myospasm is the compression of the root of the facial nerve by abnormal aligned blood vessels, while the anatomical structure and function of the facial nerve and blood vessels are normal, so in the clinical manifestation, there is no other painful manifestation except involuntary twitching of facial muscles. From clinical experience, bilateral facial muscle spasms will not affect the function of facial nerve and muscles, so patients do not need to worry too much. Microvascular decompression is the most effective way to treat facial muscle spasm, that is, the blood vessels compressing the facial nerve are found under a high magnification microscope, and the blood vessels are isolated with biological materials, relieving the compression of the blood vessels on the facial nerve, and the facial twitching is naturally lifted. The surgery is less invasive and less painful, and is the cure for facial twitching. Generally, the doctor needs to treat the side with less twitching symptoms first according to the symptoms combined with professional examination, and then perform the surgery on the other side after the body function is restored.
