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.
Intralesional injection of a steroid is done as an out-patient procedure, with no special preparation involved. You should tell the doctor if you have any allergies or problems with your general health. Although the area to be treated can be numbed with a local anaesthetic, this is not normally necessary; the discomfort associated with the steroid injection is very similar to that caused by an injection of local anaesthetic. Depending on the size of the area to be treated, a number of injections may be required. Your doctor will probably place a small dressing over the injected site, and this can be removed after a few hours. Depending on the condition being treated, you may be offered further treatment sessions, at least several weeks apart.
