The face is one of the most exposed and easily injured areas, and scarring after injury can lead to local deformities that can seriously affect a person’s aesthetic appearance. Although many scars can be improved by later plastic surgery, they are often too obvious due to improper choice of sutures during emergency treatment, which makes later repair very difficult. Therefore, timely and correct facial wound management can significantly reduce the scarring, and choosing the appropriate suture method can achieve the purpose of plastic surgery in one go. The formation of wound scar is closely related to the tension, the choice of stitches and sutures, and the suturing method. Plastic surgery generally uses smaller stitches, and for wounds with little tension, intracutaneous sutures can be performed or glued with special tissue glue, leaving no stitches and only a small thread-like scar after surgery. When the tension of the wound is high, a layered suture can be chosen to reduce the tension, and when there is too much skin loss, a local flap transfer or skin graft is needed to repair the wound. The advantages of plastic surgery for facial trauma include: 1. fine suturing 2. small stitches and fine sutures 3. no stitch removal 4. no obvious postoperative scar
