Abstract

Pyriform sinus fistula belongs to the rarest group of cervical fistulae accounting for 3 to 10% of all branchial anomalies.1 The first clinical and embryological studies were described in the early seventies by Sandborn and Tucker, but embryological knowledge in this field remains incomplete. Children and adults usually complaint of painful neck swelling accompanied by fever that is preceded by upper respiratory infection, otalgia and odynophagia. Neonates and infants may have respiratory distress, sometimes with stridor, due to tracheal compression by the abscess.1,5,6 However, the most common mode of presentation is the recurrent episodes of acute thyroiditis. Eighty percent of patients with recurrent acute suppurative thyroiditis due to persistent pyriform sinus fistula present during the first decade of life. Making the distinction between third and fourth arch fistulas is difficult on clinical grounds alone and hence they are often collectively termed pyriform sinus fistula. Owing to the rarity of the condition and varied clinical presentation, diagnosis and ultimate management is often delayed leading to undue morbidity to the patient and professional frustration for the treating surgeon. We, hereby, present a case series of three classical cases of complete pyriform sinus fistulas with review of available literature in an attempt to clarify issues regarding presentation, diagnosis and management of this condition.
