Anyone know anything about skin grafting?

You betcha! Plastic surgeons are the experts on skin grafting because we use this technique all the time to close wounds created under a variety of circumstances: injuries like burns, skin cancer removal, etc. Any time there is too much skin missing to just pull the edges together with stitches, a skin graft is an option. The skin is removed from a hidden area and transferred to the area where it is needed.
Split or full graft. A split thickness skin graft harvests the top layers of the skin but leaves enough skin substance, i.e. The hair follicles and the sweat glands, so that the donor area can heal. A full thickness graft is an ellipse of skin that can be sewn into the wound while the donor site is closed with a suture line. Full thickness grafts have less percentage take but give wounds a more cosmetic appearance.
