Templar depression is a relatively rare disease, which may be caused by localized fat metabolism disorder, or it may be a manifestation of facial hemiatrophy. In a word, its etiology is complex, rare in clinic, and the reason is not very clear. Some people think it is related to heredity; Some people think that it is a disorder of fat metabolism and a localized fat atrophy; Others think it is an immune response; Some people think it is a kind of muscle atrophy, which is obvious locally, but it may also be that the whole side has shrunk. So this is not a very clear disease, which often affects the beauty of the face. Treatment can also be through fat-filled minor surgery, local injection, hormone immunotherapy, neurotrophic and muscular nutrition drugs and so on. In short, the effect of treatment is not ideal. Once the sun is depressed, you should go to neurology, dermatology or surgery to get a correct diagnosis and make a relatively good treatment.
