1. Simple excision and suture scar repair method is suitable for small and medium-sized scars. It is best to cut along the dermatoglyphic design before surgical scar repair. After surgical scar repair removes the skin scar, carefully close the wound with a small needle and thin thread, leaving only a thin scar line after surgical scar repair. Sometimes for people with a slightly larger area and nervous skin, scar resection can also be used by stages. However, the first and second operations are usually more than half a year apart.

2. Scar excision and skin grafting. It is impossible to suture a large area of scar directly after scar resection, because there are not many normal skin in such patients. Taking facial scar as an example, surgical scar repair can be divided into different areas according to the natural shape of the face (forehead, upper and lower eyelids, nose, upper and lower lips, mandible). Surgical scar repair can patch up a whole piece of skin in the natural shape area, and decide how many parts of skin to implant according to the amount of scar resection. There is also a surgical scar repair method suitable for patients with facial scar covering the whole face, that is, removing the whole facial scar at one time; Transplantation of whole skin can avoid scar formation at joints when skin grafting is carried out in different regions, and the appearance of surgical scar repair is better than that of skin grafting in different regions. It is best to use full-thickness skin graft or skin graft with subdermal vascular network, because the facial color will not be too dark after free transplantation and the cosmetic effect will be better.
3. Repair scar with skin flap Because skin flap contains more subcutaneous adipose tissue, it can not only be used to repair skin defect after facial scar excision, but also protect deep tissue. Skin flap transplantation is also a common method to repair surgical scars near some facial organs. Such as alar defect, eyelid ectropion deformity and squab deformity. All of them need cosmetic plastic surgery based on skin flap transplantation. After transplantation, the color of skin flap is close to facial skin, and surgical scar repair can also be used to repair some facial tissue depression defects. In addition, skin flap has better blood supply and higher survival rate than free skin graft. Therefore, it is also a common surgical scar repair method in facial scar plastic surgery.
