1. Scar excision and suture: it is a common surgical method in scar treatment, and this method can be used for small scars;
2. Dermal grinding: the epidermis and dermal papillae are polished to improve the irregular part of the skin surface and make it smooth and similar in color, which is suitable for superficial scars;
3. Scar release and local plastic surgery: firstly, the cord-like and reticular scars with less tension can be removed, and then the normal skin tissue around them can be used to form a flap, which can be cross-shifted to repair the skin defect at the scar;
4. Skin expansion: It is a technique to gradually expand the covered skin area by implanting an expander in the deep skin. Skin expansion can provide "extra" and "redundant" skin to repair and replace adjacent scars or other skin defects and deformities. All kinds of scars, whether located in the head, face or trunk and limbs, can be repaired by skin and soft tissue expansion as long as the scar area is small and normal skin is available for expansion.
5. Scar excision plus free skin grafting: A large hypertrophic scar can be surgically removed, and then a free skin graft can be cut from the normal part of the body and transplanted to the scar wound to repair the wound.
