For the eyelid jumping, folklore has been circulating a “left eye jumping wealth, right eye jumping disaster”, so many people also use it to measure wealth and disaster. Until now, when the left eye jumps, many people will imply that they are going to get rich; and when the right eye jumps, the heart is often fearful and anxious. In fact, prolonged eyelid jumping may not be related to either fortune or calamity, but may be suffering from facial muscle spasm. So, what is facial spasm? What are the dangers of facial myospasm? How to treat facial muscle spasm? A. What is facial spasm? Facial myospasm, as the name implies, is a disease that occurs in the human face. The symptoms are involuntary, intermittent twitching of unilateral facial muscles, the onset of which begins with the orbicularis oculi muscle and gradually spreads to the perioral region, the neck and the entire face. The twitching is paroxysmal and irregular, often aggravated by fatigue, mental tension, and voluntary movement. Second, what are the hazards of facial muscle spasm? Facial myoclonus manifests as paroxysmal, irregular, involuntary twitches on the half side of the face, with varying degrees of severity, the lighter twitches more than ten times a day, with one twitch for a few seconds, up to more than ten minutes, with variable intervals; the more severe twitches are counted every day, and even facial atrophy and small lid fissures, seriously affecting the physical and mental health, work, study and self-esteem of patients. Therefore, when patients have long periods of eyelid jumping, they must pay attention to it, and it is recommended to go to the hospital for a detailed diagnosis. How to treat facial muscle spasm? Microvascular decompression can achieve effective treatment of facial myasthenia. The principle of surgical treatment is to open a bone window of about 3-5 cm behind the patient’s ear, find the facial nerve in the skull through the bone window, then find the blood vessel causing compression near the facial nerve, push this blood vessel to one side through surgery, so that it is far away from the facial nerve, and then place a special medical spacer between the blood vessel and the nerve, so as to achieve decompression of the nerve.
