The upper and lower lips are prominent facial features of significant importance for esthetic and functional reasons. Both lips, but especially the lower lip, are at risk for cutaneous malignancy because of their prominent location. Treatment of such malignancies creates a spectrum of defects that must be meticulously addressed by the reconstructive surgeon. These defects can be classified as small, medium, and large, and the optimal reconstructive method is typically based on this distinction. Depending on the size of the defect and the patient characteristics, reconstructive options include primary closure, local tissue transfer, and free tissue transfer.
上唇和下唇是面部突出的特征，出于美学和功能方面的重要原因。由于其突出的位置，上下唇，尤其是下唇，有发生皮肤恶性肿瘤的风险。此类恶性肿瘤的治疗会造成一系列缺损，重建外科医生必须精心处理。这些缺损可分为小、中、大三类，最佳的重建方法通常基于这种区分。根据缺损大小和患者特征，重建选择包括一期缝合、局部组织转移和游离组织转移。
