Facial nerve twitching is medically known as facial muscle spasm, resulting in paroxysmal involuntary muscle twitching of the face, which may be related to physiological factors or pathological factors, etc. When patients are diagnosed with this disease, they should actively receive regular treatment at the first time. I. Physiological factors: 1, mental stress: because of the patient’s prolonged psychological and mental stress, or long-term late night, will cause a decline in physical condition, inducing a transient nerve short circuit, resulting in the appearance of facial nerve twitching; 2, dietary reasons: irregular diet or eating a lot of cold, irritating food, may lead to enhanced facial nerve impulses, inducing patients to occur facial muscle spasm; 2, pathological factors: 1 The facial nerve is compressed: when any part of the whole link from the cerebral cortex to the branch endings of the facial nerve is compressively stimulated, the disease can be induced; 2, mechanical stimulation: granulomas, tumors and cysts commonly found in the pontocerebellar horn region compressing the facial nerve can also cause facial muscle spasm, which accounts for a relatively small proportion of the causes of facial nerve twitching in some patients; 3, neurotransmitter disorders: when patients are subjected to serious trauma or tooth extraction, severe cold and other When stimulated, the pain will stimulate the nerves to appear neurotransmitter disorder, which in turn leads to facial nerve twitching. Note: Facial nerve twitching is a chronic progressive development, and some patients will have paralysis and atrophy of the affected lateral muscles. It is recommended to go to the hospital for examination and treatment in a timely manner when facial involuntary movements occur, so as not to delay the condition.
