Supraclavicular artery island flap in head and neck reconstruction.

Due to the complex anatomy of the head and neck, a wide range of pedicled or free flaps must be available to ensure optimal reconstruction of the various defects resulting from cancer surgery. The supraclavicular artery island flap is a fasciocutaneous flap harvested from the supraclavicular and deltoid regions. The blood supply of this flap is derived from the supraclavicular artery, a direct cutaneous branch of the transverse cervical artery in 93% of cases or the supraclavicular artery in 7% of cases. The supraclavicular artery is located in a triangle delineated by the posterior border of the sternocleidomastoid muscle medially, the external jugular vein posteriorly, and the median portion of the clavicle anteriorly. This pedicled flap is thin, malleable, and is easily and rapidly harvested with a reliable pedicle and minimal donor site morbidity. It can be used for one-step innervated reconstruction of many types of head and neck defects. It constitutes an alternative to local flaps, while providing equivalent functional results and must be an integral part of the cancer surgeon's therapeutic armamentarium.
