Skin flap

A surgical technique in which a section of skin and underlying tissue, sometimes including muscle, is moved to cover an area from which skin and tissue have been lost or damaged by injury, disease, or surgery. Unlike a skin graft, a skin flap retains its blood supply, either by remaining attached to the donor site or through reattachment to blood vessels at the recipient site by microsurgery, so skin flaps adhere well even where there is extensive loss of deep tissue.
