One type of facial palsy is facial nerve impulselessness and muscle paralysis, such as sudden facial neuritis caused by air conditioning and cold wind in summer, and facial palsy caused by central nerve damage due to hypertensive cerebral hemorrhage, often accompanied by paralysis of the opposite limb. Facial spasm is the opposite of facial palsy, which is caused by involuntary muscle contraction due to overexcitation of the facial nerve, resulting in a spastic state. The vast majority is caused by vascular compression. At the end of the development of facial muscle spasm, mild facial paralysis can occur in a few cases. One type of eyelid jumping is fatigue. For most people with simple eyelid jumping, the most common causes are excessive eye use or strain, mental overstrain, such as using the computer for too long, excessive mental stress before exams, etc. One kind of eye disease, eye refractive error, myopia, hyperopia or astigmatism, intraocular foreign bodies, inverted eyelashes, conjunctivitis, keratitis, etc., can also lead to eyelid jumping. One kind of eyelid jumping is caused by facial muscle spasm, which is unilateral in the vast majority of cases and rarely bilateral. Patients with facial muscle spasm usually start with eyelid jumping, and after a few months or a year, their mouths start twitching, and to a certain extent, they cannot open their eyes and their mouths are tilted to the side. At the same time, the patient has difficulty seeing and is under great psychological stress. Physiological eyelid twitching is generally mild, and if it is overworked, it will get better after rest, and even if there is inflammation and other causes, they can all be relieved by treatment. In contrast, the cause of eyelid jumping after facial muscle spasm is in the brain, it is very difficult to heal itself, and the trend is progressive aggravation.
