Polyotia (mirror ear) is an extremely rarely reported congenital anomaly of the external ear. The aetiology of this condition is unclear, and there are few descriptions of surgical techniques used. We aimed to review our experience with this condition by performing a retrospective review of the cases treated in our unit. Eight cases of polyotia treated at a referral centre for ear reconstruction in a 12 year period (1992-2004) were reviewed. Patient demographic data and associated syndromes were recorded. Operative techniques used in the cases were studied. There was an equal number of males and females. Four patients had abnormal contralateral ears and two patients were formally diagnosed as suffering from a congenital developmental syndrome. Five main components of surgical technique were found to be particularly relevant to these cases. These relate to deconstruction of the defect, management of extra cartilage, management of skin, proximity of the facial nerve and the timing of surgery. The authors conclude that a structured surgical approach can lead to successful reconstruction of these difficult abnormalities.
副耳（镜像耳）是一种极为罕见的先天性外耳畸形。该病的病因尚不清楚，且关于所采用手术技术的描述很少。我们旨在通过对本单位治疗的病例进行回顾性研究来总结我们在处理这种情况时的经验。回顾了在一家耳再造转诊中心12年期间（1992 - 2004年）治疗的8例副耳病例。记录了患者的人口统计学数据及相关综合征。研究了这些病例中所采用的手术技术。男女患者数量相等。4例患者对侧耳朵异常，2例患者被正式诊断患有先天性发育综合征。发现手术技术的五个主要方面与这些病例特别相关。这些方面涉及缺损的解构、多余软骨的处理、皮肤的处理、面神经的位置以及手术时机。作者得出结论，结构化的手术方法能够成功重建这些复杂的畸形。
