Skin graft

A technique used to repair areas of lost or damaged skin that are too large to heal naturally, that are slow to heal, or that would leave tethering or unsightly scars. A skin graft is often used in the treatment of burns or sometimes for nonhealing ulcers. A piece of healthy skin is detached from one part of the body and transferred to the affected area. New skin cells grow from the graft and cover the damaged area. In a meshed graft, donor skin is removed and made into a mesh by cutting. The mesh is stretched to fit the recipient site; new skin cells grow to fill the spaces in the mesh. In a pinch graft, multiple small areas of skin are pinched up and removed from the donor site. Placed on the recipient site, they gradually expand to form a new sheet of healthy skin. (See also skin flap.)
