The removal and transplantation of healthy skin from one area of the body (source area or donor site) to another area (recipient area) where the skin has been damaged. The source sites most commonly used for skin grafts are the inner thigh, leg, buttocks, upper arm, and forearm.
There are three main types of skin graft techniques:
There are three main types of skin graft techniques:
- Split-thickness graft - removal of the top layer of skin (epidermis) and part of the middle layer (dermis). This type of graft allows the source site to heal more quickly. However, it is also more fragile, may be abnormally pigmented, and will not grow.
- Full-thickness graft - removal and transfer of an entire area of skin. Although this type of graft requires stitches to heal the source site, the final outcome is usually better. Full-thickness grafts are usually recommended for areas where cosmetic appearance is important, such as the face. However, full-thickness grafts can only be placed on areas of the body that have significant vascularization (blood vessels), so its use is somewhat limited.
- Composite grafts - combinations of skin and fat; skin and cartilage; or dermis and fat, which are used in areas that require three-dimensionality, such as the nose.
- Allograft
