There are four most effective methods for scar surgery.

1. Scar excision and suture: it is a common surgical method in scar treatment and can be used for small scars.

2. Skin grinding: it is a surgical method to improve the irregular part of skin surface by grinding epidermis and dermal papillae, making it smooth and similar in color. Suitable for acne, smallpox, chickenpox, herpes zoster, eczema, trauma, burns or superficial scars left after surgery. If necessary, scar treatment can be performed at the same time as surgical resection, and the effect is better than simple grinding.

3. Scar release and local plastic surgery: For the smaller tension cord-like and reticular scars, the scars can be cut off, and then the normal skin tissues around them can be used to form skin flaps, and the skin defects in the scars can be repaired by cross transposition.

4. Scar excision and free skin grafting: A large hypertrophic scar can be surgically removed, and then free skin grafting from normal parts of the body can be transplanted to the scar wound to repair the wound and restore skin function.
