Squamous cell carcinomas are the most common cancer of the lower lip. In most cases, the tumor is small and occupies less than a third of the lower lip, so the defect created can be closed with a primary suture without altering the esthetics and function of the lower lip. However, there is a percentage of large tumors that affect more than two thirds of the lower lip, in which the primary suture is insufficient to correct the defect created by resection of the tumor. Therefore, these cases require more complex reconstructions using facial locoregional flaps. Hence, in this article, the authors present a total reconstruction of the lower lip with a bilateral subcutaneous pedicled nasolabial island flap after complete resection of a squamous cell carcinoma with involvement of the entire lower lip.
鳞状细胞癌是下唇最常见的癌症。大多数情况下，肿瘤较小，占下唇的不到三分之一，因此可以通过初次缝合来闭合缺损，而不会改变下唇的美观和功能。然而，有一定比例的大肿瘤会累及下唇的三分之二以上，初次缝合不足以纠正肿瘤切除所造成的缺陷。因此，这些病例需要使用面部局部皮瓣进行更复杂的重建。因此，在本文中，作者报告了一例完全切除累及整个下唇的鳞状细胞癌后，使用双侧皮下蒂鼻唇岛状皮瓣进行下唇全重建的病例。
