对于唇缺损的整复应尽可能地应用局部或邻近区域组织瓣来恢复它的正常解剖形态和生理功能已成为公认的基本原则。本文描述了一种整复下唇缺损的新的手术方法。该方法充分利用缺损后的唇红和白唇组织，恢复口轮匝肌和唇红的完整性，使唇缺损的修复效果达到了外形与功能的完美统一。本文就该手术方法的解剖学基础，手术操作要点以及手术的适应证等问题做了较为详尽的讨论。 For the repair of lip defects, the application of local or regional tissue flap as much as possible to restore its normal anatomy and physiology has become a well-established principle. This article describes a new surgical approach to reconstruct lower lip defects. The method takes full advantage of the lip red and white lip after defect, restores the integrity of the orbicularis oris and the lip red, and achieves the perfect unification of appearance and function of the repair effect of the lip defect. This article made a more detailed discussion on the anatomy of the surgical method, the main points of the operation and the indication of the operation.
