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.
Treatment is difficult. Due to the intensity of the itch patients often go from doctor to doctor looking for relief. No one treatment is always effective and several treatments may need to be tried. Initial treatment is often potent prescription steroid creams . If these help, a milder cream can be used for longer-term control. Antihistamine creams (Zonalon, Pramoxine) or pills (Atarax, Periactin) are often added for additional relief. Intralesional steroid injections , anti-depressant pills, and non-prescription capsaicin cream helps many of those not improved with the usual treatment.
