BACKGROUND: Ideal tongue reconstruction after partial or total glossectomy should be accomplished with like tissue. The buccinator musculomucosal island flap is similar to lingual tissue, consisting of thin, pliable mucosa of mucus production, with high cell renewal rate and minimal scar formation, excellent color, contour, texture match, and buccinator muscle fibers over the flap's entire length, providing tongual muscle reconstruction without a conspicuous donor site. STUDY DESIGN: The buccinator musculomucosal island flap, based on the facial artery and vein, is designed in a shuttle or in a fish-mouth fashion, encompassing the oral commissure anteriorly. If the flap design is made in a three-leaf shape, a larger flap will be obtained without an oral corner deformity or mouth opening difficulty. The flap is safe and simple to raise. The pedicle of the flap is longer and quite reliable and has a wide range of applicability. The flap may be used for reconstruction of the partial glossectomy defect (tongual defect was not more than half a tongue). The surgeon must know about possible anatomic variations, especially in the venous system, and plan to raise a contralateral buccinator musculomucosal island flap if homolateral facial vascular variation jeopardizes the flap's survival. RESULTS: The flap was successfully used for partial tongue reconstruction in 16 patients, and all flaps have survived without complications. Satisfactory results (including configuration and function of the neotongue) were achieved. Electromyographic studies performed on one patient with half glossectomy revealed reinnervation of the muscle in the flap with active motion of the reconstructed tongue. CONCLUSION: The buccal musculomucosal island flap based on the facial artery and vein is a better reconstruction option with the same or similar kind of tissue as the tongue and, with the addition of the reinnervated flap, offers the potential for improved physiologic motion.
