As the saying goes, “the left eye jumps for money, the right eye jumps for disaster”, but in fact, many times the eyelid jumps, not only “wealth” or “disaster” of the “omen The fact is that many times eyelid jumping is not just an “omen” of “wealth” or “disaster”. Introduce, eyelid jumping is divided into physiological and pathological two. Physiological eyelid jumping is generally relatively mild, if it is overworked, will be good after rest. While the pathological eyelid jumping is complex, it is difficult to heal itself, the trend is progressive aggravation. Eyelid jumping is actually a manifestation of increased nerve excitement. Most of the eyelid jumps occur in the upper eyelid, sometimes in the lower eyelid, and are generally not controlled by the person’s mind and consciousness. Twitching at the corners of the mouth is more common on the right side, and it may also occur on the left side. In severe facial muscle twitching, the whole facial muscle and ipsilateral cervical latissimus muscle can be spasmed, and the eyes cannot be opened when the orbicularis oculi muscle is in severe spasm, thus affecting walking and work, and may be accompanied by mild weakness and muscle atrophy. The spasm may be aggravated by stress, fatigue, or voluntary movement, and disappears during sleep. Facial muscle spasms are usually not associated with pain, and the face is generally unaffected when the facial muscles are not twitching. As for the etiology of facial muscle spasm, it is not clear. It is generally believed that there are three possible causes: first, it may be caused by ectopic excitation or pseudo-synaptic transmission of the facial nerve; second, it may be due to compression of the facial nerve root by aneurysm, arteriovenous malformation or brain tumor; third, very few patients develop facial muscle twitching in the affected area after trauma, tumor or surgical operation. If facial muscle spasm is not treated, it usually will not improve naturally, and facial muscle spasm attacks will gradually become more frequent and last longer, which will seriously affect the patient’s work and life. In some patients with untreated facial spasm, facial muscle paralysis (facial palsy) can occur after several years. Therefore, patients suffering from facial muscle spasm should go to a regular hospital for treatment as soon as possible. Facial muscle spasm is a long-term compression of the facial nerve by the blood vessel friction extrusion, causing nerve demyelination lesions, which leads to nerve conduction disorders resulting in abnormal discharge of the facial nerve, manifested as involuntary twitching of one side of the facial muscles. Once the cause is found, the treatment should of course start from the “responsible blood vessel” that is compressing the nerve. Microvascular decompression is to use microsurgical techniques to observe and carefully identify the responsible blood vessel that is compressing the nerve, and then place decompression materials between the blood vessel and the nerve, so that the twitching disappears after surgery. Moreover, microvascular decompression is a minimally invasive surgery with small wounds that do not damage any nerve tissue of the face, preserving the integrity and functionality of the facial nerve, and is very safe.
