MT30-Histology Art AB 4 years, 3 months ago A skin flap is a type of wound closure. A local skin flap consists of skin taken from an adjacent area and moved to fill the surgical defect often created from the removal of a skin lesion such as skin cancer. Flaps differ from skin grafts in that a flap is transferred with an intact blood supply and remains connected to its origin, while a graft is a transfer of tissue that has been completely removed from its origin and therefore relies entirely on the recipient site for its blood supply.
This article will demonstrate that many healthcare professional students are unfamiliar with the blood supply to the skin because of its omission in most textbooks. By demonstrating the concept of skin flaps on prosected specimens, a student is introduced to the importance of blood vessel supply to muscles and the overlying subcutaneous tissues, including the skin. This method for demonstrating vascular supply to the skin may then assist students in clinical rotations where pertinent, such as observing reconstructive surgical procedures.

Some flaps known as interpolation flaps are performed in two stages. In the first stage, the skin flap is removed from its original location and sewn into the defect leaving a bridge of tissue between the two areas (the flap pedicle). The pedicle supplies the flap with blood for a couple of weeks until the second stage when the pedicle is able to be cut and sewn in to complete the repair.
