The use of a rectangular flap is a well known technique for upper lip repair in cleft lip, but is less common for lower lip repair after tumour resection. We have found this type of flap to be favourable for lower lip reconstruction, especially for the lip to mental region. We describe herein an improvement to the technique in which two opposing rectangular flaps, with the length of one side equal to the vertical distance from the mentolabial groove to the vermilion border, were raised on the lateral sides of a U-shaped defect. Reconstruction was performed by interdigitation of the two flaps and a bilateral vermilion advancement flap. This new approach allows a distinct mentolabial groove and mental protuberance to be created by utilizing two opposing rectangular flaps and redundant tissue, without sacrificing sensation and muscle function. Our results suggest that the technique provides excellent functional and cosmetic outcomes in restoration of the lower lip in properly selected patients.
使用矩形皮瓣是唇裂修复中常用的上唇修复技术，但在肿瘤切除术后下唇修复中较少使用。我们发现这种类型的皮瓣有利于下唇重建，特别是对于唇至颏部区域。在此我们描述了该技术的一种改进方法，即在U形缺损的两侧掀起两个相对的矩形皮瓣，其中一侧的长度等于颏唇沟至唇红缘的垂直距离。通过两个皮瓣的相互交错和双侧唇红推进皮瓣进行重建。这种新方法通过利用两个相对的矩形皮瓣和多余组织，能够形成明显的颏唇沟和颏隆凸，而不牺牲感觉和肌肉功能。我们的结果表明，该技术在为适当选择的患者进行下唇修复时可提供优异的功能和美容效果。
