Surgical treatment for scarsWith the continuous development of science and technology,the techniques of surgical treatment for scar tissues have continued to improve . The current mainstream surgical methods and their advantages and disadvantages are as follows. Surgical excision and direct suture is mostly suitable for scars in regular shape and with loose surrounding tissues,but the skin defect caused by scar excision is often larger than the actual area of the scar . Fractional excision is suitable for scars that are large in extent and cannot be directly sutured or implanted in one excision,such as exposed areas,the face and neck. Skin free implantation refers to the use of skin excluding subcutaneous fat tissue for autologous grafting. This method is more suitable for the excision of large scars and skin defects left after the repair of scar contracture deformity. Flap transplantation is suitable for scars involving deep tissues or at exposed areas such as the face and functional areas,which can obtain fitting skin color and texture to achieve satisfactory appearance and functional repair. Surgeons who perform this operation need to aware not to damage the blood vessels within the flap during the process. Reimplantation involves removing most of the overproliferated scar tissue and preserving the scar epidermis with a thin layer of fibrous tissue to be grafted onto the scar excised wound. This method is suitable for patients with large deep burns. He et al. reported that the reimplantation treatment for larger proliferative scars not only reduced the area of the donor area but also achieved the purpose of scar removal. Follow up showed that the vast majority of patients had no recurrence of scars. Besides,the replanted skin was flat and soft. The degree of pigmentation or absence was reduced compared with that of before reimplantation. Also,the symptoms caused by scars such as pain and itchiness basically all disappeared . Dermabrasion refers to the grinding of the epidermis and dermal papillae layer to reduce the normal skin tissue at the edge of the depressed scar,so that a new local trabecular surface is formed. Using epithelial regeneration crawling repair,the trabecular surface is re-healing. This method is mainly applicable to small depressed scars left by smallpox,chicken pox,acne and other skin diseases that have been cured and stabilized . Another surgical method is skin soft tissue expansion,which uses the expansion effect of tissue expanders to obtain additional skin soft tissue for the repair of skin defects and organ reconstruction. Since the skin soft tissue expansion for the buried site is mostly from the normal adjacent tissue. After expansion the additional skin obtained can match the skin of the healthy area in terms of color,texture,structure and hair content .","department":"
