For small scars, plastic surgeons usually choose the method of excision and suture. When cutting, they should follow the dermatoglyphics as much as possible, so that the wound can heal better, sometimes leaving only a thin linear scar.

If the scar is large or contracture deformity occurs, most of the scar should be removed and then repaired with skin graft or flap. Whether it is skin grafting or skin flap repair, plastic surgeons take various methods to ensure the survival of skin flap or skin flap and increase the cosmetic effect after operation. The more well-trained plastic surgeons, the better the cosmetic effect of surgery.
