dc.description.abstract	ABSTRACT Polyotia is an anomaly of the external auricle in which the accessory auricle is large enough to closely resemble an additional pinna rather than a skin remnant and cartilage. Polyotia, also known as mirror ear or accessory ear, is a type of ear anomaly in the tragus area, but the term refers to substantial anomalies which resemble an accessory ear, unlike a pre-auricular tag. It is an extremely rare condition and to date, less than 30 cases of polyotia have been reported according to a review of the literature. A variety of theories has been proposed for development of such abnormal external auricle. We report two cases of polyotia which presented to Dhulikhel Hospital ENT OPD that was successfully corrected surgically. An 8-year-old boy and a 14-year-old boy presented with a large accessory anomalous auricle on left and right ear respectively. The accessory auricle was composed of an elastic cartilaginous component covered with skin and was positioned anteriorly to the original auricle in both the cases. The anomaly was not as large as the patient’s external auricle, rather it mirrored the external auricle. On the opposite ear both the cases presented with pre- auricular skin tag. Surgical correction was done by dissecting the skin free from the duplicated cartilage via an incision along the free edge of the helix the duplicated cartilage was contoured to fill the pre-tragal hollow and the tragus reconstructed with a free cartilage graft.
