Skin flaps are sections of skin that are surgically moved from one area of the body to another. They are often used in reconstructive surgery to cover wounds or defects, providing both skin and underlying tissue. This technique helps promote healing and restore the appearance of the affected area. There are different types of skin flaps, including local flaps, which are taken from nearby skin, and free flaps, which are detached and then reattached to a new site with its blood supply. Skin flaps are commonly used in procedures involving cancer removal or traumatic injuries.
