Buccinator Myomucosal Flap for Reconstruction of Glossectomy Defects

Abstract

Objective. The use of the myomucosal flap from the buccinator muscle is a valuable reconstruction method for intraoral defects. We report the clinical advantages and pitfalls of using the buccinator myomucosal flap for tongue reconstruction after intraoral resection of tongue cancer. Study Design. Prospective study. Setting. University hospital. Subjects and Methods. We used buccal artery-based buccinator myomucosal flaps for tongue reconstruction in 11 partial or total edentulous patients who underwent resection of tongue cancer. The size and site of the tongue defect ranged from one-third to one-half of the tongue in the lateral border. We analyzed the clinical features and oncologic and functional outcomes to define adequate indications. Results. All flaps were successfully harvested and transposed, and the donor sites were primarily closed. The pedicles were safely divided 2 to 3 weeks postoperatively. In 8 of 11 patients, concurrent upper neck dissection was performed without compromising blood supply to the flap. The range of tongue motion and the volume of the reconstructed tongue were satisfactory, and the patients experienced no difficulties in swallowing or speech. Conclusion. Particularly in edentulous patients, the buccal myomucosal flap can be a good option for reconstructing partial tongue defects after cancer surgery.
