Skin grafts will not survive on tissue with a limited blood supply (cartilage, bone or tendons) or tissue that has been damaged by radiation treatment.

The wound must be free of any dead tissue, foreign matter, or bacterial contamination.



If the entire thickness of the dermis is included, the appropriate term is full-thickness skin graft (FTSG).

If less than the entire thickness of the dermis is included, this graft is referred to as a split-thickness skin graft (STSG).
STSGs are categorized further as:

-Thin (0.005-0.012 in),
-Intermediate (0.012-0.018 in), or
-Thick (0.018-0.030 in), based on the thickness of the harvested graft.

The choice between full- and split-thickness grafting depends on wound condition, location, thickness, size, and aesthetic concerns.

STSGs require less ideal conditions for survival and have a much broader range of application than FTSGs.

STSGs are used to resurface large wounds, line cavities, resurface mucosal deficits, close flap donor sites, and resurface muscle flaps.


The surgeon first marks the outline of the wound on the skin of the donor site, enlarging it by 3–5% to allow for tissue shrinkage.
The surgeon uses a dermatome (a special instrument for cutting thin slices of tissue) to remove a split-thickness graft from the donor site. The wound must not be too deep if a split-thickness graft is going to be successful, since the blood vessels that will nourish the grafted tissue must come from the dermis of the wound itself.
The graft is usually taken from an area that is ordinarily hidden by clothes such as the buttock or inner thigh and applied on the wound.
Gentle pressure from a well-padded dressing is then applied, or a few small sutures used to hold the graft in place. A sterile non adherent dressing is then applied to the raw donor area for approximately three to five days to protect it from infection.
