Polyotia is an extremely rare congenital anomaly of the external ear. Only four case reports are documented in the literature. A 13-month-old child with a mirror-image duplication of the left auricle was operated on in a one-stage corrective procedure. The duplicated portion of the affected ear was positioned anteriorly and measured approximately two-thirds the size of the posterior, normally oriented portion. There were two fully developed conchae and one fully developed and one partially developed anthelix and lobule. The entire complex had a single external auditory meatus and no tragus. There were no other congenital anomalies, and the child was developmentally normal. The technique for surgical correction is described, and a review of the literature is presented.
多耳畸形是一种极其罕见的先天性外耳异常。文献中仅记载了4例病例报告。一名13个月大的儿童，其左耳呈镜像重复，接受了一期矫正手术。患耳的重复部分位于前方，大小约为后方正常部分的三分之二。有两个完全发育的耳甲，一个完全发育和一个部分发育的对耳轮及耳垂。整个复合体有一个外耳道，没有耳屏。没有其他先天性异常，该儿童发育正常。文中描述了手术矫正技术，并对文献进行了综述。
