Abstract : Preauricular sinus is a common congenital malformation. It was first described by Van Heusinger in 1864. It is formed from incomplete or abnormal fusion of the six auditory hillocks during embryological development of the auricle at the 6th week of intra-uterine life. The prevalence of preauricular sinus differs depending on the population ranging from 0.1% - 0.9%, in the USA; 0.9%, in England and 4% - 10% in some parts of Africa. They present as an asymptomatic pit like depression anterior to the root of the helix and superior to the level of tragus, not requiring any treatment if asymptomatic. Unusual presentations can be subtle with some difficulty in obtaining diagnosis. Some patients presenting with discharge due to recurrent infections of sinuses require antibiotic therapy and surgical resection of the sinus tract. Here is a case series of an atypical presentation of Preauricular sinus along with a postauricular cyst. Any patient presenting with recurrent postauricular abscess without any pathology in mastoid with a small pit in the preauricular area should be suspected to have preauricular sinus.
