The auricular conchal cavity is a shallow structure in the central part of the ear. It is not only 3-dimensional, but it is a gateway to the external ear canal. Many methods have been described for reconstruction of the defect of concha-antihelix: split- or full-thickness skin grafts, regional skin, chondrocutaneous and musculocutaneous flaps, but none of the authors have described this flap with neurovascular pedicle. We used postauricular neurovascular pedicle island flap for conchal and periconchal areas of anterior surface of the external ear because it matches to the skin color, thickness and texture; scars are well hidden, and there is no donor-site morbidity. Moreover, it has a constant and reliable neurovascular pedicle. The flap edema which was present in the early postoperative period began to resolve gradually after 3 weeks and disappeared in a few months. The esthetic results were excellent in all of the patients and very satisfying for the patients, too. The sensibility was positive by light touch, pin-prick, temperature and static 2-point discrimination in the postoperative control. The static 2-point discriminations in the transferred flap and in the other ear, which corresponds to the same area, were measured. The results were nearly the same as normal values. We advocate postauricular neurovascular pedicle island flap for conchal and periconchal areas of anterior surface of the external ear because it matches the skin color, thickness and texture; scars are well hidden, and there is no donor site morbidity. Moreover, it has a constant and reliable neurovascular pedicle.
耳甲腔是耳部中央的一个浅结构。它不仅是三维的，而且是外耳道的入口。已经描述了许多用于重建耳甲-对耳轮缺损的方法：断层或全厚皮片移植、局部皮肤、软骨皮瓣和肌皮瓣，但没有作者描述过这种带神经血管蒂的皮瓣。我们使用耳后神经血管蒂岛状皮瓣修复外耳前表面的耳甲和耳甲周区域，因为它与皮肤颜色、厚度和质地相匹配；瘢痕隐藏良好，且供区无并发症。此外，它有恒定且可靠的神经血管蒂。术后早期出现的皮瓣水肿在3周后开始逐渐消退，并在几个月内消失。所有患者的美学效果均极佳，患者也非常满意。术后复查时，通过轻触、针刺、温度测试和静态两点辨别觉测试，感觉均为阳性。测量了转移皮瓣和对侧对应相同区域的另一只耳朵的静态两点辨别觉。结果与正常值几乎相同。我们主张使用耳后神经血管蒂岛状皮瓣修复外耳前表面的耳甲和耳甲周区域，因为它与皮肤颜色、厚度和质地相匹配；瘢痕隐藏良好，且供区无并发症。此外，它有恒定且可靠的神经血管蒂。
