The funny and humorous Zhao Si in “Country Love” impresses everyone, especially Zhao Si’s highly comedic facial twitches that are the most soul-crushing. The facial twitching of Zhao Si is medically known as facial muscle spasm, also known as facial twitching, which is manifested as involuntary twitching of one side of the face. The twitching is paroxysmal and irregular, and the degree varies, and the twitching can be aggravated by fatigue, mental tension and voluntary movement. The onset of the twitching mostly starts from the orbicularis oculi muscle and then involves the whole face on one side. It occurs more often after middle age and is more common in women than men. The initial symptom of facial myospasm is eyelid jumping, which is also known as “left eye jumping for money, right eye jumping for disaster”, so it usually does not attract people’s attention, but after a period of time, it develops into facial myospasm, even to the corners of the mouth, and in serious cases, even to the neck. Facial muscle spasm can be divided into two types, one is primary facial muscle spasm, one is secondary facial muscle spasm, that is, facial muscle spasm produced by the sequelae of facial paralysis. The two types can be distinguished from each other in terms of symptoms. In primary facial myospasm, it can occur even at rest, and the spasm is relieved after a few minutes and is uncontrolled; in facial myospasm produced by the sequelae of facial palsy, it is produced only when doing actions such as blinking and raising eyebrows. What causes facial muscle spasm? It is known that about 80% to 90% of facial muscle spasms are due to the presence of vascular compression from the facial nerve out of the brain stem area to the cranial out of the skull segment. In addition, non-vascular occupying lesions in the pontocerebellar horn, such as sarcoidosis, tumors and cysts, can also produce facial muscle spasm. What are the dangers of long-term facial myasthenia? First, because long-term rotten medication to control facial myospasm seizures will cause liver, kidney function, microvascular system is affected, over time, will lead to anemia, insomnia, facial muscle contracture, joint band movement, ptosis, psychosis and other occurrences, and even brain, liver and kidney failure, life-threatening. Secondly, patients with facial myoclonus will also cause patients to become depressed, depressed, often feel tired, and long-term untreated even cause personality changes, low self-esteem and autistic tendencies. Since facial muscle spasm has so many hazards, we are most concerned about what can be done to treat this disease. In addition to drugs such as phenytoin sodium or carbamazepine, which may be effective for some mild patients, general central sedatives, depressants and hormones are not significantly effective. Some people advocate acupuncture for facial muscle spasm, but experts recommend that it is best not to acupuncture, because the disease itself is afraid of stimulation, sometimes acupuncture will aggravate the disease, some people then effective, but later relapse up will be powerful. In addition taking carbamazepine or phenytoin sodium these anti-sedative anti-epileptic drugs only control, and long-term use of side effects are also very large, dependence is also relatively strong, there is no radical treatment possible. In recent years, some people treat facial spasms by injecting botulinum toxin, which can control the condition to a certain extent, usually one injection can control for up to one year, but a long time injection will produce drug resistance, and because botulinum toxin type A can paralyze the nerves of the face causing artificial facial paralysis, so the facial spasms will be controlled at that time, but patients who have been injected for a long time will have more or less symptoms of facial paralysis. Currently, the most effective treatment for facial spasm is surgery. Microvascular decompression is a common method of neurosurgery used internationally to treat facial myasthenia. It is a mature, simple, less risky, less invasive procedure with only a few centimeters of incision, and does not damage brain tissue or nerves.
