Skin graft or skin flap. Skin grafts or skin flaps are done after the scar tissue is removed. Skin grafts involve replacing or attaching skin to a part of the body that is missing skin. Skin grafts are performed by taking a piece of healthy skin from another area of the body (called the donor site) and attaching it to the needed area. Skin flaps are similar to skin grafts, where a part of the skin is taken from another area, but with the skin flaps, the skin that is retrieved has its own blood supply. The section of skin used includes the underlying blood vessels, fat, and muscles. Flaps may be used when the area that is missing the skin does not have a good supply of blood because of the location or because of damage to the vessels.
With the advance in medical technology, a lot of treatments become available for hypertrophic scars. By destroying each tissue of scar from the skin’s top layers and then exposing the skin’s lower layers, laser therapy is one of the most effective ways to removing hypertrophic scars. Whether this method is long-term or short-term will mostly depend on the scar’s severity. For your best benefit, you should work with an expert to figure out the most suitable option based on the skin condition, the types and severity level of your scars. The successful hypertrophic scar treatment requires a well-designed plan that suits your problems.
In this procedure, the old scar is removed and new incisions are made on each side, creating small triangular flaps of skin. These flaps are then rearranged to cover the wound at a different angle, giving the scar a "Z" pattern. The wound is closed with fine stitches, which are removed a few days later. Z-plasty is usually performed as an outpatient procedure under local anaesthesia. While Z-plasty can make some scars less obvious, it won't make them disappear. A portion of the scar will still remain outside the lines of relaxation, these are the scars which do not blend into the ‘wrinkles’ of the skin.
