Skin grafts are classified into two types: split-thickness and full-thickness grafts. A split-thickness skin graft involves only the top layer of the skin, which is treated as a sheet. This type of graft is used to cover large areas of skin loss such as from burns. Full-thickness skin grafts include both the epidermis and the dermis. These grafts are used to treat severe wounds or skin defects. The donor site for full-thickness grafts must be larger than that for split-thickness grafts. In general, patients prefer split-thickness skin grafts because they heal faster than full-thickness grafts. However, full-thickness grafts provide better coverage because they contain more skin cells. The choice between split- and full-thickness grafts should be based on how much skin is missing and what type of wound is being treated. Burns and other trauma can cause significant damage to the skin, including scarring and pigment changes. Skin grafting is an important part of the treatment for these conditions. During skin grafting, healthy skin is removed from another area of the body and transferred to the injured skin.
