自1984年以来,作者用颊肌肌粘膜瓣修复肿瘤切除后下颌骨骨髓炎造成的缺损、腭瘘、较宽腭裂修复。解剖行14具尸体解剖。颊肌在颊部的位置较深,内侧口腔粘膜外侧位于下颌骨升支、翼内肌、嚼肌、颊脂垫和颊咽筋腹下。颊肌与颊咽筋膜下部构成筋膜间隙。手术时在此层极易分离。颊肌在前与口轮匝肌缠绕,在后进入翼颌间隙,上部平上颌骨水平,下至下颌骨。腮腺导管穿过颊肌,开口于第二磨牙所对的颊粘膜。
Since 1984, the authors used buccal muscularis mucosal flap to repair defects caused by mandibular osteomyelitis after resection of the tumor, palatal fistula, and a wide cleft palate repair. Anatomy of the line 14 with autopsy. Buccal muscles in the cheek location deeper inside the lateral oral mucosa in the mandibular ascending branch, wing muscles, chewing muscles, buccal fat pads and buccal pharyngeal tendons under the belly. Buccal muscle and buccal fascia under the fascia to form the gap. Surgery in this layer easily separated. Buccal muscles in front of the orbicularis orbicularis muscle wrap, after entering the wing jaw space, upper level of maxillary level, down to the mandible. Parotid duct through the buccal muscle, opening in the second molar on the buccal mucosa.
