Bilobed flaps, transposition repairs used primarily on the nose, recruit tissue from an area of laxity via rotational motion. A variant of the bilobe, the two-lobed flap based on the W-plasty, is a transposition flap that shifts tissue predominantly via advancement.
To apply the two-lobed advancement flap to the problem of reconstructing cutaneous helical rim defects of the ear.
Helical two-lobed advancement flaps were designed and implemented to correct small- to medium-sized defects.
The ear helix was successfully repaired with two-lobed advancement flaps. There was minimal distortion of the ear architecture or cartilage, and blood supply was sufficient to ensure flap viability.
In selected cases, cutaneous helical rim defects of the ear can be aesthetically repaired with a two-lobed advancement flap derived from the posterior auricular surface.
双叶皮瓣主要用于鼻部的转位修复，通过旋转运动从松弛区域募集组织。双叶皮瓣的一种变体，即基于W成形术的双叶皮瓣，是一种主要通过推进来移位组织的转位皮瓣。
将双叶推进皮瓣应用于修复耳部皮肤螺旋缘缺损问题。
设计并实施螺旋双叶推进皮瓣以纠正中小型缺损。
双叶推进皮瓣成功修复了耳螺旋。耳部结构或软骨的变形极小，血液供应充足以确保皮瓣存活。
在选定的病例中，耳部皮肤螺旋缘缺损可用源自耳后表面的双叶推进皮瓣进行美观修复。
