Surgical scars must be removed by surgery. The following are several surgical methods to remove scars:

1. 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.

2. Facial scar excision plus skin grafting

It is impossible to suture a large area of scar directly after scar removal, because there is not much 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.

3. Repair the scar with skin flap.

Because the flap contains more subcutaneous adipose tissue, it can not only be used to repair the skin defect after facial scar resection, but also protect the 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.

4. Non-surgical treatment of facial scar

For some hypertrophic scars that do not affect facial function, sometimes surgery is not needed, because even after resection, it is very easy to relapse and produce new hypertrophic scars. In order to soften and flatten the scar, the following methods can be used for cosmetic treatment.

(1) Compression therapy People gradually apply compression therapy to scar hyperplasia after burns, and the effect is positive. After facial scar excision, the surgical incision needs to be pressurized for 6 months to 1 year. This can effectively prevent scar hyperplasia.

(2) Drug therapy 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 its color to or near the normal complexion of the face. But sometimes it takes several injections to achieve the desired effect.

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