Plastic surgery is based on the principle of reducing the exposure range of patients' wounds, exposing lesions well and facilitating surgery. Therefore, the less tissue exposure at the incision, the better, and the closer the incision is to the lesion, the easier it is to operate. The principle of cosmetic surgery is to compare the surgical effects, reduce postoperative incision exposure and scar hyperplasia, and the surgical operation requires precision and accuracy to avoid unnecessary tissue damage.

Surgery can be divided into surgical plastic surgery and non-surgical plastic surgery (micro-plastic surgery, injection beauty, laser skin care, etc. Plastic surgery aims at saving lives, and complications are easily understood by patients and their families. However, cosmetic surgery aims at beauty and commercial interests, and complications are often not accepted by patients and their families, which is prone to medical disputes. Therefore, cosmetic plastic surgeons are required not only to have solid basic medical knowledge and superb surgical techniques, but also to have high aesthetic accomplishment, so as to minimize the occurrence of complications.

The effect of plastic surgery depends on the doctor's experience (60%), the patient's condition (30%) and luck (10%). Plastic surgery is not everything. I hope that the surgical effect of thousands of people is ignorant. Surgery can turn ugly ducklings into white swans, but it can't turn ants into elephants. Don't expect too much from plastic surgery. Unhappy clothes can be discarded, and improper operation will hurt life. Good foundation, surgery and makeup can achieve the best beautiful effect. It is unwise to sell iron at the expense of beauty. It is best to get the consent of your family before the operation to avoid disputes in the future. Improperly cut clothes are not easy to change, and the second operation is more difficult to repair. There are many problems that plastic surgery cannot solve. Plastic surgery can only solve objective problems, but not subjective ones. It is inappropriate to use beauty as a bargaining chip and hope to achieve a certain goal through plastic surgery.
