Restoring the cosmetic and functional aspects of the lip after tumor resection is challenging. We report a case of reconstruction for a defect due to resection of a melanoma using a lower lip musculomucosal flap combined with a tongue flap. A 20-year-old man was referred to our hospital and diagnosed with malignant melanoma with metastatic right submaxillary lymph nodes. We excised the tumor with neck dissection. We excised not only the right upper lip mucosa but also the gum, including some orbicularis oris muscle and alveolar bone from the right canine tooth to the left central incisor tooth. The defect was simultaneously reconstructed using both, a lower lip musculomucosal flap and a tongue flap. Revisional operation to remove contraction of a postoperative scar and the right vermillion border collection was performed at 3 months after the initial operation. There had been no functional and cosmetic trouble of the upper lip.
肿瘤切除术后恢复唇部的美观和功能颇具挑战性。我们报告一例使用下唇肌黏膜瓣联合舌瓣修复黑色素瘤切除术后缺损的病例。一名20岁男性被转诊至我院，诊断为伴有右侧颌下淋巴结转移的恶性黑色素瘤。我们进行了肿瘤切除及颈部清扫术。我们不仅切除了右上唇黏膜，还切除了牙龈，包括从右侧尖牙到左侧中切牙的部分口轮匝肌和牙槽骨。同时使用下唇肌黏膜瓣和舌瓣修复缺损。在初次手术后3个月进行了修复手术，以消除术后瘢痕挛缩和右侧唇红缘积液。上唇未出现功能和美观问题。
