Different treatment methods should be adopted for different scars to achieve better curative effect. There are many ways to remove scars, some of which are small, narrow, sunken or stable scars, which can be cut and stitched in stages. Scar release and local plastic surgery are suitable for cord-like or reticular scars, so as to release or remove the scars and transfer the surrounding normal skin tissues to the scar defect. Scar excision and free skin grafting are suitable for large hypertrophic scars, which can be surgically removed, and then free skin grafting is taken from hidden parts of the body and transplanted to the scar wound to repair the scar wound and restore the body function. Skin tissue expansion is a kind of reconstruction skin grinding that makes adjacent normal skin and soft tissue gradually increase in a certain period of time by artificial means, and then uses these expanded redundant skin tissues to repair the defective tissues and organs. For some burn scars whose surface is convex or concave, the scars can be repaired by mechanical grinding, which can make the skin smooth and restore good color. Scar excision flap transplantation is the skin tissue cut from a certain part of the body after scar excision, which is connected with the body with a pedicle to maintain the blood circulation needed for its survival, and then transferred to the defect area to achieve the purpose of repairing the skin defect. The Beauty and Plastic Surgery Center of China Armed Police General Hospital has done many successful cases of scar excision and skin flap transplantation, and the postoperative recovery is quite beautiful.
