title: Right-sided pyriform sinus fistula in an adult.
abstract: Pyriform sinus fistula is important despite its rarity, as it can induce a recurrent neck abscess. Most of the reported cases occur in children and the majority affect only the left side. We report a patient with a pyriform sinus fistula of the right neck in an adult, which was successfully treated by surgery. The aetiology of this entity is also discussed herein.
