Various reconstruction methods using local flaps have been reported for upper lip defects. The reverse Yu's flap is a reconstruction method consisting of three flaps including the advancement flap, rotating flap, and mucosal flap. It offers the advantage of low risk of microstomia occurrence because this method restores the form of the vermilion using buccal mucosa as a mucosal flap. Herein, we report the case of a 77-year-old Japanese man who underwent reconstruction using a modified reverse Yu's flap for a defect following the resection of right upper lip basal cell carcinoma. The patient presented with a 4.2×3.5 cm mass on the right upper lip. Resection was planned, and the anticipated defect in the vermilion following resection measured approximately 3.5 cm, making primary closure unfeasible. Thus, the defect was reconstructed using a reversed Yu's flap with minor modifications to accommodate the larger defect. The modifications to the technique are described herein and have been designated as the "anchor flap" due to the characteristic shape of the incision line.
已有多种使用局部皮瓣的上唇缺损重建方法被报道。反向俞氏皮瓣是一种由推进皮瓣、旋转皮瓣和黏膜瓣三个皮瓣组成的重建方法。该方法具有发生小口畸形风险低的优点，因为此方法使用颊黏膜作为黏膜瓣来恢复唇红的形态。在此，我们报告一例77岁日本男性患者，其因右上唇基底细胞癌切除术后缺损接受了改良反向俞氏皮瓣重建术。患者右上唇出现一个4.2×3.5 cm的肿物。计划进行切除，切除后预计唇红部的缺损约为3.5 cm，无法进行一期缝合。因此，使用改良的反向俞氏皮瓣对缺损进行重建，为适应更大的缺损做了一些小的改动。本文描述了该技术的改动情况，由于切口线的特征形状，将其命名为“锚定皮瓣”。
