Advancement flaps are surgical techniques used in reconstructive surgery to close wounds or defects in the skin. They involve moving a section of tissue, which includes skin and underlying structures, from one area to another while maintaining its blood supply. This method helps ensure proper healing and reduces the risk of tissue necrosis. These flaps can be classified into various types, such as local flaps and regional flaps, depending on their origin and the distance they are moved. Advancement flaps are particularly useful for covering areas with limited skin availability, such as on the face or limbs, enhancing both function and appearance.
