Trapezius Osteomyocutaneous Flap in Reconstructive Surgery for Mandibular and Oral Defects

Abstract

A scapular-trapezius osteomyocutaneous flap was used for mandibular reconstruction in 4 cases of oral cavity carcinoma after segmental resection of the mandible. In 3 cases, both the flap and bone took well, and the functional and morphological results were satisfactory. In one case, impaired venous return resulted in flap necrosis; a second reconstruction was performed using a rib-latissimus dorsi osteomyocutaneous flap. Functional disturbances of the donor site were minimal and, because the donor site was on the back, the cosmetic result was excellent. This flap is a bone-attached compound flap using the transverse cervical artery and veins as the vascular bundle, and is thought to be useful in the reconstruction of mandibular defects associated with extensive tissue defects of the oral cavity.
