单侧唇裂三叶瓣修复术

目的 设计一种新的唇裂修复的手术方法,旨在减少术中组织损失,有效下降患侧唇峰,并使手术瘢痕更加符合人中嵴形态,且更有利于鼻尖的上抬和鼻底的成形.方法 唇裂修复分鼻尖、鼻底和唇部三个区域分别完成.健侧白唇区域设计三叶形皮瓣.上方二皮瓣梯次向鼻小柱外侧和鼻底旋转,分别用于修复鼻尖上抬后鼻小柱旁的组织缺损,并重建鼻底区鼻堤结构,剩余的下方皮瓣向患侧不加旋转而直接推进,与患侧皮瓣直接缝合,在下降唇峰并恢复患侧人中嵴形态的同时,使手术的切口瘢痕与健侧人中平行,形态更接近自然.结果 本组48例患者伤口均一期愈合,未发生任何血运障碍.唇峰下降满意,鼻底丰满度良好,鼻堤结构成形满意,同时鼻尖形态恢复较好,鼻孔横置现象得到明显改善,人中嵴形态良好.结论 应用三叶瓣术式可避免以往唇裂修复术唇峰下降不足或白唇附加切口的缺陷,无需三角瓣的补充.术中同时恢复鼻尖高度并得到足够的鼻底组织量和良好鼻堤形态,术后切口瘢痕与对侧人中嵴对称.

Trilobate technique, a new principal to repail cleft lip

Objective To develop a new method for reparation of cleft lip, and to evoke more colleagues for advance practices and study, in order to determine her indication and contraindication as soon as possible. Methods 48 cases were included into this study. Trilobate flap were Designed in floor of nose and lip area in cleft side, rotate two of the three flaps upwards, rspectively to elevate the tip of nose, and to reconstruct the floor of nose. As for the left flap, it was drived transversally to opposing side, sutured with the flap of non-cleftside. Results With this technique, less tissue was lost, better vertical lengthening and good formed cupids-bow was achieved, and the sear was a parallel line being symmetry to the philtrum column opposide. Meanwhile, because the tension was mainly located in the area where there was no mini flaps, the blood supply was good enough, rarely occur any necrosis in the tip of flaps. All cases in this study obtained perfect healing, with good appearance at nostrils and floor of nose. Conclusions In use of the method of trilobate flap, we can draw down the peak of the cupids bow effectually, hence avoid the addition cut in the lower part of the lip, decrease the scar on skin, as well as nice reconstruction of floor of nose, philtrum column and nostril. Because lack of long term study, we evoke more colleagues for cooperation in advance study.
