Based on the scar you exhibit, a plastic surgeon can recommend and perform a variety of scar revision procedures. The appropriate technique depends on the type of scar, its size, age, and other factors. Plastic surgeons offer both surgical and non-surgical techniques to reduce the appearance of scars. For some of these procedures, such as local flap surgery, the doctor may perform tissue expansion techniques, which help the skin to adequately stretch in order to make reconstruction possible.
