应用颊肌肌粘膜瓣修复口腔癌术后缺损10例。方法根据缺损大小和部位设计制作单侧或双侧、蒂在前或蒂在后的不规则梯形肌粘膜瓣。将其旋转修复不同部位缺损，6例修复舌、牙龈、口底、咽侧区，2例单侧瓣修复翼下颌皱襞，2例双侧瓣修复口底正中缺损。结果本组病例肌粘膜瓣全部成活，1例近期有轻度开口受限，2周后恢复正常，口腔粘膜无明显修复痕迹及收缩现象。结论颊肌肌粘膜瓣是口腔内软组织缺损理想的修复材料。
Application of Musculocutaneous Musculocutaneous Flap to Repair Postoperative Defect of Oral Cancer in 10 Cases. Methods According to the size and site of the defect design made unilateral or bilateral, pedicle anterior or pedicle in the trapezoidal muscle flap. Six cases of tongue, gums, mouth bottom and pharyngeal region were repaired by rotating them. Two cases of unilateral flaps repaired the mandibular fold, and two cases of bilateral flap repaired the median defect of the mouth. Results All the musculocutaneous flaps survived in this group. One case had mild opening limited recently and returned to normal after two weeks. There was no obvious signs and contractions in oral mucosa. Conclusion Buccal muscular mucosal flap is an ideal repair material for oral soft tissue defects.
