There are two basic types of skin grafts: split-thickness and full-thickness grafts.
A split-thickness graft involves removing the top layer of the skin — the epidermis — as well as a portion of the deeper layer of the skin, called the dermis. These layers are taken from the donor site, which is the area where the healthy skin is located. Split-thickness skin grafts are usually harvested from the front or outer thigh, abdomen, buttocks, or back.
Split-thickness grafts are used to cover large areas. These grafts tend to be fragile and typically have a shiny or smooth appearance. They may also appear paler than the adjoining skin. Split-thickness grafts don’t grow as readily as ungrafted skin, so children who get them may need additional grafts as they grow older.
A full-thickness graft involves removing all of the epidermis and dermis from the donor site. These are usually taken from the abdomen, groin, forearm, or area above the clavicle (collarbone). They tend to be smaller pieces of skin, as the donor site from where it’s harvested is usually pulled together and closed in a straight-line incision with stitches or staples.
Full-thickness grafts are generally used for small wounds on highly visible parts of the body, such as the face. Unlike split-thickness grafts, full-thickness grafts blend in well with the skin around them and tend to have a better cosmetic outcome.skin graft, skin graft surgery, skin graft cost, skin transplantation, skin graft pain, skin graft care, skin graft in iran,graft surgery,transplantation of skin
