Simple excision and suture method: Simple excision and suture method is suitable for the third kind of small and medium-sized facial scars. After the skin scar is removed, carefully suture the wound with a small needle and thin thread, preferably along the dermatoglyphics, leaving only a thin scar line after operation. 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.

Facial scar excision plus skin grafting: it is impossible to directly suture a large area of scar after scar excision, because there are not many normal skin on the face of such patients. At this time, a whole piece of skin can be repaired in a natural shape according to the natural shape of the face (forehead, upper and lower eyelids, nose, upper and lower lips, lower jaw), and several parts of skin can be planted according to the amount of scar resection. Another method is suitable for patients with facial scar covering the whole face, that is, removing the whole facial scar at one time; Transplanting a whole skin can avoid the scar formation at the junction of skin grafting in different areas, and the postoperative appearance is better than that of skin grafting in different areas. 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.

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 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 the flap is close to the facial skin, and it 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, so it is also a common method in facial scar plastic surgery.

Non-surgical treatment of facial scars: for some hypertrophic scars that do not affect facial function, sometimes surgical resection is not needed, because even if they are removed, they are very easy to recur and produce new hypertrophic scars. In order to soften and flatten the scar, the following methods can be used for cosmetic treatment.

Compression therapy People gradually apply compression method to scar hyperplasia after burn, and the effect is positive. Generally, after facial scar resection, the surgical incision needs to be pressurized for 6 months to 1 year. This can effectively prevent scar hyperplasia.

Drug treatment practice has proved that injecting hormone suspensions such as prednisolone acetate and triamcinolone acetonide acetate into the hyperplastic part of facial scar can flatten the hyperplastic scar and restore the color to or near the normal skin color of the face. But sometimes it takes several injections to achieve the desired effect.

Radiotherapy For small area hypertrophic scar on face or hypertrophic scar after skin grafting, shallow X-ray radiotherapy should be performed, and generally 4-6 times can achieve good results.
