Abstract：
BACKGROUND: The traditional nasolabial V-Y advancement flap is widely used for midface reconstruction, particularly for the lower third of the nose and upper lip, as its color and texture are similar to these areas. However, it provides insufficient tissue to cover large defects and cannot restore the nasal convexity, nasal ala, and adjacent tissues. The purpose of this study is to investigate the modified nasolabial V-Y advancement flap with extension limbs the along alar crease for the reconstruction of complex midface defects.
METHODS: A retrospective analysis of 18 patients, who underwent reconstruction with the modified nasolabial V-Y advancement flap, was performed between September 2014 and December 2022. An extension limb was added along the alar crease, adjacent to the defect area, and was hinged down as a transposition flap at the end of the advancement flap.
RESULTS: The extension limb along the alar crease successfully covered large and complicated defects, including those of the ala, the alar rim, the alar base, the nostrils, and the upper lip, with minor complications.
CONCLUSIONS: The alar crease is a good donor site for the reconstruction of large and complex nasal and upper lip defects.

摘要：
背景：传统的鼻唇沟V-Y前移皮瓣广泛用于中面重建，特别是鼻子和上唇的下三分之一，因为它的颜色和纹理与这些区域相似。然而,它提供的组织不足以覆盖大的缺损，并且不能恢复鼻凸，鼻翼,和邻近的组织。目的探讨改良鼻唇沟V-Y前移皮瓣加长四肢沿鼻翼折痕重建复杂中面缺损的疗效。
方法：回顾性分析18例患者，用改良的鼻唇沟V-Y推进皮瓣进行了重建，在2014年9月至2022年12月期间进行。沿着鼻翼折痕增加了一个延伸肢体，邻近缺陷区域，并在前进襟翼的末端以换位襟翼的形式向下铰接。
结果：沿着鼻翼折痕的延伸肢体成功地覆盖了大而复杂的缺陷，包括那些阿拉，Alar边缘，阿拉尔基地，鼻孔，和上唇，轻微的并发症。
结论：鼻翼折痕是重建大型复杂鼻和上唇缺损的良好供体部位。
