Shao Zhen: Facial plastic surgery is the same as plastic surgery in other parts of the body. After surgery, we usually use drugs mainly in several aspects. The first one is to prevent infection. Wound infection is a serious problem, and the drugs used are mainly some antibiotics. There is also a kind of medicine that can reduce swelling, and there is also a kind of medicine that can relieve pain. But it is not necessary to use these three drugs in every operation, it depends on the specific situation. Analgesic drugs are generally not needed after bone grinding, but some people are sensitive to pain and need to use them when they feel pain, which varies from person to person due to different operations.
