Regional flaps are surgical techniques used in reconstructive surgery to repair defects in the skin or underlying tissues. They involve moving a section of tissue, including skin, fat, and sometimes muscle, from a nearby area of the body to cover a wound or defect. This method helps ensure that the transferred tissue retains its blood supply, promoting better healing. These flaps can be classified into different types, such as local flaps and pedicled flaps, depending on how the tissue is moved. Regional flaps are often preferred for their ability to provide a good match in color and texture, making them ideal for facial or limb reconstructions.
