It is human nature to love beauty and Marx said, “The pursuit of beauty is the symbol of the progress of human civilization.” As our standard of living as well as education improves, life is beautifying, and likewise the body, which is why plastic and cosmetic surgery has caught fire in recent decades. Children’s plastic surgery has only specialized in the last few years, taking on the main task of dealing with scarring in addition to repairing various congenital and acquired deformities! That is, in solving functional problems while focusing on aesthetics, the following is a brief introduction to the problem of scarring. 1.Why do scars form? Scars are a natural product of the wound healing process. Scars are like glue that allows wounds (or incisions) to grow together, and without scarring there would be no wound healing. 2. Do all wounds form scars? No. Superficial wounds that only injure the epidermis of the skin will not form scars after healing. Wounds that are deeper than the dermis and subcutaneous tissues (such as surgical incisions) require scars to repair, and once formed, scars will not fade naturally throughout life. 3.How to reduce or inhibit scars? In addition to the preoperative design and various fine operations during the operation, the following measures need to be taken in order to make the wound (or incision) become more beautiful. (1) Pressure therapy: (elastic sleeve, elastic clothing, elastic bandage, etc.) through pressure to make the blood vessel lumen in the scar become narrower, less blood flow, scar tissue lack of nutrients and inhibit its proliferation. (2) Topical medication: Silicone creams or patches can reduce the evaporation of skin moisture and inhibit the regeneration of capillaries in the scar tissue, thus softening the scars. (3), laser: selective action on the supply of scar blood vessels, so that its lumen closure, fibrosis, interruption of the nutritional supply of the scar, to achieve the purpose of inhibiting scarring. Note: All methods can only inhibit the growth of scars, not completely remove scars. 4.The best time to treat scars? Generally speaking, the growth period of scars is within 1-6 months after wound healing, and in some cases, it may extend to 1 year or even longer. The above treatments are only effective for scars in the growth phase. Old scars can be treated with morcellation and fractional laser. In conclusion, plastic surgery treatment is a sequence of treatment process, including preoperative scientific design, intraoperative fine operation, a series of postoperative anti-scar treatment. Plastic surgery operation is very important, but it is only an important part of this sequence, only by doing a good job of the whole set of measures, scars will be minimized, and the incision will be more aesthetically pleasing.
