Medical image A 5-year-old female child presented with pain and swelling in front of the left ear for 3 days. She had a similar episode 2 years back. Examination revealed a warm, tender swelling with a sinus at the root of helix of the left ear (Fig. 1). A diagnosis of infected preauricular sinus was made and the patient was started on oral amoxicillin. The swelling was aspirated and antibiotics were continued for 7 days. Her symptoms resolved and her parents were counselled for surgical removal of the sinus. Preauricular sinus is a congenital malformation and first described by Van Heusinger in 1864 [1]. The incidence varies from 0.3–0.9% and has an autosomal dominant inheritance with incomplete penetrance and variable expression. Both sexes are equally affected and it is usually unilateral. It is usually seen as a pit or depression near the external ear, most commonly adjacent to the root of helix. It may be associated with other congenital anomalies, such as hearing loss or renal disorders (Branchio-oto-renal syndrome). They develop due to incomplete fusion of auricular hillocks or inversion of ectoderm during development of the auricle. Most patients are
asymptomatic; however, infection of the pit leads to a discharging sinus or abscess. Recurrent infections can lead to cellulitis, perichondritis and hypertrophic scar formation and are an indication of surgical excision. Recurrence is common since the tract can have extensive branching leading to incomplete removal.
