![]() Most commonly, STSG autografts are taken from the lateral thigh, as well as trunk, as these sites are both aesthetically hidden, as well as easy to harvest from due to their broad surfaces. Split-thickness skin grafts are obtainable from multiple sources (autograft, homograft, allograft, or xenograft), multiple anatomical locations, and in various thicknesses. Unlike flaps, skin grafts do not have their own blood supply, so they must rely on a well-vascularized wound bed for graft in-growth. ![]() After incorporation, skin grafts provide wounds with protection from the environment, pathogens, temperature, and excessive water loss like normal skin.Ī split-thickness skin graft (STSG), by definition, refers to a graft that contains the epidermis and a portion of the dermis, which is in contrast to a full-thickness skin graft (FTSG) which consists of the epidermis and entire dermis. The rationale of skin grafts is to take skin from a donor site that will heal and transfer the skin to an area of need. Skin grafting is the transfer of cutaneous tissue from one portion of the body to another, often used to cover large wounds.
