Postauricular sinus is an uncommon variant of preauricular sinus. We reported a 4-year-old girl with right post-auricular sinus with its opening was at the pinna crus helix. She had recurrent history of infection and required surgical excision. Two approaches were described as unidirectional and bidirectional excision approaches. The preferred approach depends on the variation of the sinus track and sac extension, bidirectional approach being the most common. In this case, the postauricular sinus sac extended medially to temporalis fascia and parotid. Nevertheless, the sinus was successfully excised via unidirectional method.
