1. “It is easy to get infected in the summer when it is hot” is not true. Whether or not infection occurs is related to the severity of the disease, strict sterilization, postoperative care, and the heat is not directly related. In fact, surgeons never stop surgery in summer. In addition to some surgeries that require thick postoperative dressings, which can be staggered during the hot season as appropriate, other surgeries are not affected by this. 2. “Surgical wounds are afraid of wind and cold” is not true. In addition to a few surgery is the need to moisturize, the general wound and the wind blowing, the cold does not have much to do with. The key is to keep the wound clean. 3. “Fish is a hairy food, eating it will make the wound infected” is not true. Western medicine believes that the necessary post-operative supplementation of high-protein, high-vitamin diet can speed up wound healing. 4. “If you bleed during surgery, you will be greatly injured” is not true. Cosmetic surgery bleeds very little, usually a few dozen milliliters to one or two hundred milliliters. This bleeding will be replenished in a short time for a healthy person and will not hurt at all. If some surgeries do cause more bleeding, the doctor will arrange for blood transfusion in advance. 5. “There will be rebound after liposuction” is not true. Human fat cells are terminally differentiated cells and the number is fixed. The principle of liposuction is to destroy and suck out a large number of fat cells, and the remaining fat will not have the ability to regenerate. Therefore, after effective liposuction, the volume of the remaining fat cells is limited to increase again. 6. “Scar can be completely eliminated” is not true. Whether with topical drugs, excision or grinding, the scar cannot be completely eliminated, but only the heavy scar becomes light, and the obvious scar becomes inconspicuous.
