In life, when you notice that someone is squeezing his/her eyebrows incessantly. This is not sending you any special signals, he or she may be suffering from facial muscle spasm. Facial muscle spasm is a common comprehensive facial nerve disease. The initial clinical manifestations are involuntary twitching of the corners of the mouth, fluttering of the eyelids, and involuntary tilting of the corners of the mouth. Most people pay more attention to the treatment of facial muscle spasm, hoping that the condition can be controlled in the early stage of the disease. So, how to treat mild facial muscle spasm? Diagnosed with facial muscle spasm, when the disease is mild, you can take some B vitamins, or other nutritive nerve drugs, such as methylcobalamin, adenosine glutamate, etc. under the guidance of the doctor; if the eyelids, mouth corners twitching is particularly strong, you can inject botulinum toxin A, in a certain period of time to temporarily ease the spasm of the symptoms. However, these drugs are also only nutritive to the nerves, and cannot solve the most direct problem, because the drugs are not directed, which will cause all the nerve signals to slow down, and the patient will suffer from side effects such as drowsiness and unresponsiveness. Clinical studies have confirmed that the cause of facial muscle spasm is due to the compression of the root of the facial nerve by abnormally shaped blood vessels. The facial nerve is thus pathologically stimulated, such that abnormal neurophysiological impulses are generated, which manifest as muscle twitching in the face. Although the facial muscles may twitch from time to time, the patient’s facial nerve and muscle function are intact, so only the blood vessels and nerves need to be isolated to achieve a cure.
