The cutaneous surgeon commonly encounters defects of the helix, as 2-4% of all skin cancers occur at this site.
We report our experience with 47 patients using the chondrocutaneous helical rim advancement flap of Antia and Buch.
Incisions are made from the defect inferiorly into the lobule and, when necessary, superiorly along the helical sulcus into the helical crus. The postauricular skin is extensively undermined to allow maximal movement of the resulting broadbased, well-vascularized flap(s).
We experienced very favorable results using this technique with our patients. No necrosis due to ischemia occurred in any of our cases. Hematomas formed postoperatively in two patients, but healing proceeded uneventfully after removal of coagulated blood.
This technique is an excellent method of repairing many defects of the helical rim. Its advantages include technical simplicity, little risk of tip necrosis, patient convenience, and superior cosmesis.
皮肤外科医生经常遇到耳轮缺损，因为所有皮肤癌中有2% - 4%发生在这个部位。
我们报告了使用安蒂亚和布赫软骨皮肤耳轮缘推进皮瓣治疗47例患者的经验。
从缺损下方切口至耳垂，必要时沿耳轮沟向上至耳轮脚。广泛分离耳后皮肤，以使形成的宽基底、血运良好的皮瓣能够最大程度地移动。
我们对患者使用该技术取得了非常好的效果。我们的病例中没有因缺血导致的坏死。两名患者术后形成血肿，但清除凝血后愈合顺利。
该技术是修复耳轮缘许多缺损的极佳方法。其优点包括技术简单、尖端坏死风险小、患者方便以及美容效果好。
