A flag flap, in the context of surgical reconstruction, is a skin flap shaped like a flag, where the pole represents the pedicle carrying the blood supply. This design allows for localized tissue transfer in reconstructive surgery.
In more detail:
-
Definition: It's a type of skin flap used in reconstructive surgery. Its distinguishing feature is its flag-like shape, with the "pole" of the flag being the pedicle through which the blood vessels travel to nourish the flap.
-
Function: The flag flap is raised and rotated to cover a nearby defect or wound. The pedicle, containing the blood supply, ensures the flap remains viable.
-
Variations: Flag flaps can be designed in different ways, including:
- Proximally Based: The pedicle (pole) is located closer to the body's central axis.
- Distally Based: The pedicle (pole) is located further away from the body's central axis. According to provided context, distally based dorsal flag flaps are studied.
-
Use Cases: Flag flaps are utilized in various reconstructive procedures, often for covering small to medium-sized defects on the limbs or digits.
In essence, the flag flap is a surgical technique for transferring healthy skin and tissue to cover a wound or defect, relying on a pedicle containing blood vessels to keep the transferred tissue alive.
