1), scar excision and Chen's ultra-fine suture technique Some small and narrow sunken or stable scars can be treated by scar excision and suture or by stages. 2), scar release and local plastic surgery. Streak or reticular scar with tension can loosen or remove the scar, and make the normal skin tissue around it cross-shift and rotate to the defect part of the scar. 3) Scar excision plus free skin grafting. Hypertrophic scars with large size can be surgically removed, and then free skin grafts are cut from hidden parts of the body and transplanted to scar wounds to repair scar wounds and restore body functions. 4) Scar excision and skin flap transplantation After scar excision, the skin tissue cut from a certain part of the body is connected with the body with a pedicle to maintain the blood circulation needed for its survival, and then it is transferred to the defect area to achieve the purpose of repairing the skin defect. 5) Skin tissue expansion refers to the gradual expansion of adjacent normal skin and soft tissue in a certain period of time by artificial means, and then the damaged tissues and organs are repaired by using these expanded "redundant" skin tissues. This technology has changed the previous situation of "robbing Peter to pay Paul". It can not only provide rich skin and soft tissue with similar color, texture and function to the skin and soft tissue in the defect area for the repair and reconstruction of tissue defect, but also overcome the disadvantages of the second defect of donor site left over by traditional methods, which is a major technological revolution in plastic surgery. The treatment process can be roughly divided into three stages: two-stage operation and a series of expansion periods for a certain period of time. First, a tissue expander was implanted in a predetermined normal skin area. After the wound healed completely, a series of injection dilations were started, lasting 1-3 months. Once the expected expansion size is completed, these expanded "redundant" skin and soft tissues are reasonably transferred to the scar area to be repaired, thus completing the repair of these skin and soft tissue defects and organ reconstruction. The whole treatment usually takes several months. 6) Skinning method For some burn scars with high or sunken surface, mechanical polishing can be used to make the skin smooth and restore good color. 7) Tattoo Camouflage Method Some burn scars with only skin color changes can make use of the tricolor principle to prepare tattoo granule liquid with normal skin color, tattoo the scar area and cover it up. In a word, there are many methods to treat burn plastic scars, and they also have good curative effects. But the treatment of scar is a systematic project, and different scars need different treatment methods to achieve better curative effect.
