Abstract

OBJECTIVE: The aim of this study was to describe a rare intra-auricular sinus. An otherwise healthy 15-year-old girl presented with recurrent infections in her right pinna from early infancy. Physical examination revealed a draining sinus which opened to the descending helical limb, while its cystic component was entrapped within the cartilaginous antitragus. Comprehensive surgical excision was performed after the tract and the more distal cyst was delineated. Surgical pathology revealed a true sinus, measuring 2 cm. Follow-up was unremarkable. DISCUSSION: In addition to the two previously described variants of pre-auricular cyst: the classic variant (the pit is anterior to the external auditory canal) and the postauricular variant (the pit is behind the ascending limb of the helix), we suggest a third variant which opens to the descending helical rim.
