Facial myoclonus is a common neurosurgical disorder that develops mainly on one side of the face and is characterized by involuntary facial twitching. The twitching is paroxysmal and irregular, with varying degrees of severity. The onset of the twitching usually begins in the orbicularis oculi muscle and, if left untreated, will gradually expand to the face and corners of the mouth. Facial spasm is a chronic progressive disease, and if no treatment is taken, the symptoms will not disappear on their own, but will be at risk of worsening. Based on the results of clinical treatment, surgery is currently a viable treatment for facial myospasm. So, how is minimally invasive surgery for facial myasthenia gravis performed? Microvascular decompression is a medically recognized procedure for facial muscle spasm. The procedure is performed under a microscope to subtly release the adhesions between the facial nerve and blood vessels with mature technology, simple operation and good results. Although facial muscle spasm is not a fatal disease, it can cause unnatural facial expressions, restlessness, irritability, insomnia, and even facial muscle atrophy, which can affect life, work and study. If left untreated, a vicious circle will be formed. Thus, patients are advised to take microvascular decompression treatment as soon as possible after the diagnosis of the condition to restore themselves to health as soon as possible.
