Polyotia.

Abstract

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.
