Various flap procedures for the reconstruction of lower lip defects have been described to achieve the basic requirements of a functional repair, namely muscle function and sensation. Flaps elevated from the upper lip or the adjacent cheek may provide a solution, but for larger lower lip defects, preservation of function is difficult. In this article, a new functional lower lip reconstruction technique that includes the transfer of a myocutaneous flap based on the mental neurovascular bundle and on the branches of the facial artery is described. The principle of this reconstructive procedure is to advance the tissues from both sides of the chin as myocutaneous flaps upward to the lip defect, reorienting the muscles of the flap for sphincteric function, and preserving the mental nerve for sensation. The depressor anguli oris and remnants of the orbicularis muscle together with their motor nerve branches are included in the V-Y advancement flap.
为实现功能性修复的基本要求，即肌肉功能和感觉，人们已经描述了多种用于下唇缺损重建的皮瓣手术方法。从上唇或相邻脸颊掀起的皮瓣可能提供一种解决方案，但对于较大的下唇缺损，功能的保留很困难。在本文中，描述了一种新的功能性下唇重建技术，该技术包括基于颏神经血管束和面动脉分支转移肌皮瓣。这种重建手术的原则是将下巴两侧的组织作为肌皮瓣向上推进至唇部缺损处，重新调整皮瓣的肌肉以实现括约肌功能，并保留颏神经以恢复感觉。降口角肌和口轮匝肌的残余部分及其运动神经分支包含在V-Y推进皮瓣中。
