1. Facial atrophy belongs to denervated atrophy, and facial nerve can regulate the metabolism of facial muscles. After nerve trunk injury, due to the loss of nerve regulation, the corresponding tissues can atrophy. If this kind of facial muscle atrophy occurs, we must choose a regular hospital to improve it, otherwise it is likely to lead to unsatisfactory surgical results. The symptom of facial muscle atrophy is that the protein synthesis of atrophic cells decreases and the decomposition increases to adapt to the living environment with low nutritional level. Facial nerve can regulate the metabolism of facial muscles. When the nerve trunk is damaged, the corresponding tissues will have symptoms of facial muscle atrophy due to the loss of neuromodulation. The symptom of facial muscular atrophy refers to the atrophy caused by the lack of centripetal stimulation of nerve receptors and the decrease of centrifugal impulse when facial muscles can not exercise for a long time, which leads to the gradual decrease of substance metabolism or blood supply. After the cause is eliminated, the cells can return to normal. The rapid growth of facial muscles can alleviate the symptoms of muscle atrophy, because fat tends to accumulate in the buttocks and abdomen, while facial muscles and fat grow slowly. Some concrete methods are needed, which can not only promote the blood circulation of the face, but also enrich the facial muscles, improve the skin and make the face rosy. Drugs that nourish brain cells are mainly used, such as cerebrolysin, citicoline, Naofukang, vitamin B complex, inosine tablets, etc. Quit smoking and drinking, avoid eating food containing alum such as fried dough sticks, and add drugs to treat symptoms, such as drugs to control mental symptoms. If there are complications such as lung infection, anti-inflammatory treatment is needed at the same time.
