Whether or not surgery can remove scars is generally based on an objective analysis of whether or not the patient is a scar patient and the size of the patient’s scars. In general, it is not recommended that patients undergo surgery to remove scars, as minor scars can be achieved with good results by laser means. Only if the scars are poorly cared for, or if the patient himself does not pay attention to them, or if the scars left by trauma, such as burns or scalds, reach a very serious level, only mechanical or surgical means can be used for treatment. There are three methods of surgical scar removal as follows: 1. Implantation: All the larger scars are removed, and then the full layer of skin from other parts of the body is cut and sutured to the scar removal wound. If the scar is treated by implantation, the skin color of the implantation area will be obviously contrasted with the surrounding area after healing, and there will be suture marks around the implantation area, and the skin removal area will leave a scar that is twice as big as the area of the recipient area, so the final healing effect is not very satisfactory; 2.Cut-and-sew surgery: the scar will be removed, and the normal skin on both sides after the scar is cut will be pulled together and sutured to the middle. This method is suitable for small scars, and there are scalpel stitches and stitch marks left after surgery, and there is a possibility of widening of the stitches after surgery; 3. Skin expansion technique: After using the normal skin around the scar for expansion, the scar excision expansion skin is transferred to repair the scar excision post-trauma. In addition, repeated infections, long-term trauma exposure, excessive proliferation of granulation tissue, dust, talcum powder, fibers and residual hair follicles, sebaceous glands and sweat glands can cause tissue reactions, leading to scar proliferation and prone to hyperplastic scars or scarring.
