Skin-grafting

Skin grafting, a type of graft surgery, involves the transplantation of skin without a defined circulation. The transplanted tissue is called a skin graft. Surgeons may use skin grafting to treat: extensive wounding or trauma burns areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans specific surgeries that may require skin grafts for healing to occur – most commonly removal of skin cancers Skin grafting often takes place after serious injuries when some of the body's skin is damaged. Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: reducing the course of treatment needed (and time in the hospital), and improving the function and appearance of the area of the body which receives the skin graft. There are two types of skin grafts: Partial-thickness: The more common type involves removing a thin layer of skin from a healthy part of the body (the donor section). Full-thickness: Involves excising a defined area of skin, with a depth of excision down to the fat. The full thickness portion of skin is then placed at the recipient site. A full-thickness skin graft is more risky, in terms of the body accepting the skin, yet it leaves only a scar line on the donor section, similar to a Cesarean-section scar. In the case of full-thickness skin grafts, the donor section will often heal much more quickly than the injury and causes less pain than a partial-thickness skin graft. A partial thickness donor site must heal by re-epithelialization which can be painful and take an extensive length of time.
