作者等曾报告应用含有皮肤、颊肌、颊粘膜的复合岛状颊瓣修复局限性颈段食管狭窄的方法。近来又将此方法扩展用于头颈部其它部位的重建。瓣的血管蒂为面动、静脉。面动脉在横过下颌骨体时恰在下颌角前的小沟中,极易摸到。在下颌骨下4cm处,以面动脉为中心横行切开皮肤和颈阔肌,仔细解剖面动脉直到接近二腹肌;面前静脉则追溯到与面总静脉汇合处。这些血管的走行可有变异,常发生分支,在切断分支前必须了解其走向,以决定取舍。面神经的下颌支在
The authors have reported the use of complex cheek flap containing skin, buccal muscle, buccal mucosa to repair localized cervical esophageal stenosis. This method has recently been extended for the reconstruction of other parts of the head and neck. Vascular pedicle for the face flap, vein. Facial artery in the mandibular body just across the mandibular angle before the small groove, easily touched. At 4cm below the mandible, the transverse cutaneous and platysma were cut transversely to the facial artery, and the facial artery was carefully dissected until it approached the abdominal muscles. The anterior vein was traced back to the confluence with the facial veins. These vessels may have variability in the walk, often occur in the branch, before cutting off the branch must understand its direction to decide the trade-offs. Facial nerve mandibular branch in
