The rhombotrapezius myocutaneous and osteomyocutaneous flaps.

As more radical surgery is being performed for head and neck cancer, an increasing variety of flaps for reconstruction have been developed. The more common myocutaneous flaps for large defects are the pectoralis major, trapezius, and latissimus dorsi flaps. The lower trapezius flap, which is used for reconstruction of large lateral facial defects, is a relatively thin flap. The rhombotrapezius flap described in this article provides bulk for augmentation of facial defects. The flap, which includes the trapezius and rhomboid muscles, also offers a longer pedicle with a greater arc of rotation. This flap may include the medial border of the scapula when bone is necessary. The addition of the rhomboid muscles incorporates the dorsal scapular artery, which gives an additional blood supply to the flap. We believe that the rhombotrapezius, myocutaneous, and osteomyocutaneous flaps have a significant advantage over previously described flaps in the treatment of defects that need greater bulk and length for adequate reconstruction.
