The buccinator muscle is a wide, flat quadrangular muscle. Its medial surface is covered by the oral mucosa. It receives its arterial blood supply from two main arteries: the facial and buccal arteries. A musculo-mucosal flap can be raised on the facial artery with or without the facial vein. In the case of absence of the facial vein, venous drainage is possible into the peri-arterial loose areolar tissue. A nasolabial skin incision facilitates facial artery identification and simplifies flap dissection in the loose areolar plane, superficial to the facial artery. The mean dimensions of the flap are 3.5 cm in width and 7 cm in length. The flap extends from the superior buccal sulcus to the inferior alveolar ridge. Its rotation enables reconstruction of the anterior and lateral floor of the mouth. The donor site is closed in two layers. The authors present a series of ten patients reconstructed with this flap after excision of a squamous cell carcinoma of the floor of the mouth. The results are excellent with perfect tongue function and no esthetic sequelae. The facial artery should be preserved during neck dissection, and the ipsilateral mandibular molar teeth must be extracted. Its simplicity and reliability makes this flap a useful alternative in floor of mouth reconstruction.
颊肌是一块宽阔、扁平的四边形肌肉。其内侧表面被口腔黏膜覆盖。它主要从两条动脉获得血液供应：面动脉和颊动脉。可以在面动脉上掀起带或不带面静脉的肌黏膜瓣。在没有面静脉的情况下，静脉血可引流至动脉周围疏松的乳晕组织。鼻唇皮肤切口有助于识别面动脉，并简化在面动脉浅面的疏松乳晕平面中的皮瓣解剖。皮瓣的平均尺寸为宽3.5厘米、长7厘米。皮瓣从上颊沟延伸至下牙槽嵴。其旋转可用于重建口腔前部和外侧底部。供区分两层缝合。作者介绍了一系列10例患者，这些患者在切除口腔底部鳞状细胞癌后用该皮瓣进行了重建。结果非常好，舌功能完美，没有美学后遗症。在颈部清扫术中应保留面动脉，同侧下颌磨牙必须拔除。其操作简单且可靠，使该皮瓣成为口腔底部重建的一种有用替代方法。
