Subcutaneous Pedicle Flaps to The Lip
J. N. BARRON

The use of subcutaneous pedicle flaps in lip reconstruction is limited, partly because of the multitude of excellent standard flaps available and partly because of the difficulty in achieving a mobile lip unless functioning orbicularis muscle is incorporated in the flap when repairing full-thickness defects (1). For these reasons, subcutaneous pedicle flaps usually are limited only to skin defects (2, 3, 4). Platysma musculocutaneous flaps from the neck are excellent for reconstructing the lower lip (see Chapter 174).
FLAP DESIGN AND DIMENSIONS
In men, it is important to repair lip defects with a hair-bearing flap, and whenever possible, bulky mushroomed flaps should be avoided, especially when replacing a concave surface, such as the mentolabial groove. The main sources of subcutaneous pedicle flaps for the repair of lip defects are the nasolabial fold, the chin, and the lip itself.
