The wrap-around flap (WAF) has become a popular approach to thumb reconstruction because the results are functionally and cosmetically excellent. By modifying to a partial toenail transfer, the WAF can also be used for finger reconstruction. However, performing cosmetically superior finger reconstruction is a significant challenge because it is difficult to reconstruct the natural nailfold by partial nail transplantation, although partial nail transplantation is required to reconstruct a narrow fingernail. One side of the reconstructed lateral nailfold tends to be a missing nail margin, and one side of the proximal nailfold angle tends to be retracted. Based on the rationale that loss of the lateral nailfold volume due to the postoperative tension of the volar flap would result in a missing nail margin, the volume of the lateral nailfold was maintained with a single thread that was passed from the nail to the volar flap. Additionally, half of the proximal nailfold from the nail plate was elevated to advance it forward. The results indicated that a cosmetically natural nailfold was achieved with the WAF approach to finger reconstruction. These easy and simple techniques enable reconstruction of a cosmetically natural nailfold using WAF for finger reconstruction.
环抱皮瓣(WAF)已成为拇指再造的常用方法,因为其功能和外观效果都非常出色。通过改良为部分趾甲移植,WAF也可用于手指再造。然而,要实现外观上更优的手指再造是一项重大挑战,因为尽管重建狭窄指甲需要进行部分指甲移植,但通过部分指甲移植很难重建自然甲襞。重建的外侧甲襞一侧往往缺少指甲边缘,近端甲襞角的一侧往往会回缩。基于掌侧皮瓣术后张力导致外侧甲襞体积丢失会导致指甲边缘缺失的理论,用一根从指甲穿至掌侧皮瓣的单线维持外侧甲襞的体积。此外,将甲板近端甲襞的一半掀起并向前推进。结果表明,采用WAF法进行手指再造可实现外观自然的甲襞。这些简单易行的技术能够利用WAF进行手指再造,重建外观自然的甲襞。
