It is a reconstructive procedure that involves moving a section of tissue from one part of the body to another while still attached to its blood supply. This is used to repair or reconstruct areas of body that have been affected by trauma, surgery, cancer removal or other issues that have resulted in tissue loss or damage. There are several types of tissue flaps including local flaps, regional flaps and distant flaps, each with its own specific applications and benefits. Flaps, also known as free flaps, involve taking tissue from a distant place along with its blood supply and joining its blood supply to a new site.
