Reconstruction of the mandibular arch after ablative surgery of the oral cavity is extremely difficult. Recently, in cases of more complex defects, including bone and soft tissue loss, an osteomyocutaneus flap is commonly used for one-stage repair. This study examines the trapezius myocutaneous flap incorporating the spine of the scapula in reconstructive surgery for mandibular and oral defects.We utilized this technique in 3 patients with oral cavity carcinoma. All the patients had been irradiated and treated with anti-cancer drugs before operation. In one patient this technique failed because of stagnant venous return caused by an intraoperative procedure. Reconstruction was performed by a compound rib-latissimus dorsi osteomyocutaneous flap two days after operation. All the patients had successful healing with excellent esthetic and functional resuslts. The 99mTc labeling bone scan and panorex radiographs showed evidence of active bony turnover. The spine of the scapula-trapezius osteomyocutaneous flap is thus useful for repair procedures for mandibular and oral defects.
