自1979年 Ariyan 首次描述胸大肌肌皮瓣以来,它已被广泛用于重建头颈部缺损,包括口内缺损。近年来,胸大肌肌皮瓣的设计有了许多改进,例如同时携带肋骨或胸骨重建下颌骨,利用皮瓣之皮岛修复口内粘膜缺损。虽然对应用这一皮瓣已积累了不少经验,但多数报道都侧重于皮瓣成活率和手术并发症。而对用胸大肌肌皮瓣重建口内缺损时皮肤成份的变化如何,则尚无研究报道。本文研究了皮瓣之皮肤成份从胸壁转移到口腔。
Since Ariyan first described the pectoralis major myocutaneous flap in 1979, it has been widely used to reconstruct head and neck defects, including intraoral defects. In recent years, there have been many improvements in the design of the pectoralis major myocutaneous flap, for example, the reconstruction of the mandible while carrying the rib or sternum, and the repair of the oral mucosal defect using the skin island of the flap. Although much experience has been gained with the use of this flap, most reports focus on flap survival and surgical complications. However, there is no research on the changes of skin composition in the reconstruction of the oral defect with the pectoralis major myocutaneous flap. This article studies the skin component of the flap from the chest wall to the oral cavity.
