Abstract A mouth floor mucosal flap was developed to reconstruct medium-sized intraoral buccal defects, too large for primary closure if major functional and aesthetic impairment is to be avoided. Although free flaps, perforator flaps, or even skin grafts can be designed for buccal reconstruction, they may not provide good mucosal sensitivity, motility, volume, and texture to replace lost structures with similar tissue. Moreover, secondary morbidity can be avoided with this adjacent flap.In our study, 8 flap reconstruction procedures were performed from March 2009 to July 2011: 4 cases of leukoderma, 2 cases of buccal cancer (T1 N0 M0), and 2 cases of papillary epithelioma. The largest size amount to 5.3 × 3.8 cm (length × width), with a mean of 4.3 × 3.4 cm. Compared with free flaps (forearm arm flap for example) for buccal reconstruction, application of the mouth floor flap has its indications. First, to secure the motility of tongue and function of mouth opening, the upper bound of the defects was below the occlusion line. Generally, the width between top and bottom was less than 4 cm. Second, at least a partial buccinator muscle can be preserved after lesion resection and then facial collapse can be avoided. Third, patients had molar absence or relevant teeth had to be extracted during surgery.All patients recovered from intraoral surgeries with good objective and subjective speech and swallowing and aesthetics and without injury to the lingual nerve, the submandibular gland duct, and the sublingual gland. Results indicate that the mouth floor mucosal flap is reliable and technically easy for reconstructing medium-sized intraoral buccal defects, with good function and aesthetics with little secondary morbidity.
