Subcutaneous Pedicle Flaps

Skin and lining defects of the cheek can be repaired by mobilizing an appropriate island of skin from adjacent redundant areas of the cheek (Figs. 103.1 and 103.2). The nasolabial fold is an ideal abundant source of tissue for the repair of adjacent skin defects (4, 5). It has a robust blood supply and provides an excellent texture and color match. Circular defects of the cheek also can be repaired by using two sliding subcutaneous pedicle flaps (6) (Fig. 103.3). Skin defects of the neck can be repaired by suitably designed subcutaneous pedicle flaps, although other techniques, such as free skin grafts or standard flaps, are usually preferred.
It should be noted that subcutaneous pedicle flaps should not be used to repair circular defects less than 2 cm in diameter, especially in the lax region of the cheek, because peripheral scar contraction can cause mushrooming of the flap.
