背景对于耳缘缺损超过2.5cm，且软骨框架无缺损和低舟状骨受累的患者，作为一种延迟方法，一种有用的重建工具包括从邻近区域提起的管状皮瓣。用这种技术治疗的患者有三例被狗咬伤，一例被人咬伤，一例摩托车事故，最后两例烧伤。三种不同的情况下获得性边缘缺陷，即上升上级螺旋，下降螺旋，并与小叶参与尾eleventh，显示。在螺旋重建中，管宽度不得超过15 mm，管长度必须比缺损长1 cm。没有调节皮瓣。没有椎弓根桥插入沿着主要管。两次分裂之间的间隔平均约为5周。7名患者接受了这种技术治疗：在所有情况下，我们没有感染或皮肤坏死。为了避免管的收缩，必须估计皮瓣尺寸和螺旋缺损之间的正确比例。虽然它被认为是一种古老的技术，并且是一种多阶段的重建序列，但在边缘缺损超过2.5 cm宽的情况下，该手术可能是首选。这是因为它自然恢复了螺旋的解剖结构。
BACKGROUND. A useful reconstructive tool, as a delayed method, for marginal defects of the ear of more than 2.5 cm wide with no deficit of the cartilaginous frame and low scapha involvement, consists of tubed flaps raised from neighboring areas. The patients treated with this technique sustained a dog bite in three cases, a human bite in one case, a motorcycle accident in one case, and finally, a burn trauma in two cases.OBJECTIVE. Three different cases of acquired marginal defects, namely ascending superior helix, descending helix, and cauda elicis with lobule involvement, are shown.METHODS. In the helix reconstruction, the tube width has not to be more than 15 mm, and the tube length has to be 1 cm longer than the defect. There was no conditioning of the flaps. No pedicle bridge was interposed along the major tube. The interval between two divisions was on average approximately 5 weeks.RESULTS. Seven patients were treated with this technique: In all cases, we had no infections or skin necrosis. To avoid a shrinkage of the tube, a correct ratio between flap dimensions and helical defect has to be estimated.CONCLUSION. Although it is considered an old technique and it is a multistage reconstructive sequence, this procedure could be the first preference in cases of marginal defects more than 2.5 cm wide. This is because it restores naturally the anatomy of the helix.
