Diagnosis and treatment of pyriform sinus fistula in neonates

Abstract

Objective To summarize the features of the diagnosis and treatment of pyriform sinus fistula in neonates. Methods Between July 2001 and January 2010,9 neonates were diagnosed with pyriform sinus fistula and treated at this department. The age at diagnosis, clinical features, results of ultrasound or CT examination, treatment and prognosis in all patients were retrospectively reviewed to summarize the characteristics of the diagnosis and prognosis of neonatal pyriform sinus fistula. Results The pyriform sinus fistulas of the 9 patients were on the left lateral neck. All patients visited doctors for cystic neck masses. Eight patients symptoms started in neonatal period, and 1 patient was diagnosed before birth. The CT scanning of the 5 patients found gas in the masses. Seven patients underwent surgery in neonatal period,and were followed up for 6 months to 9 years after surgery. No recurrence of pyriform sinus fistula was noted. Conclusions The neonatal pyriform sinus fistula usually starts with painless and cystic neck mass without history of abscess incision and drainage. Ultrasonography or CT could find gas in cysts. The surgical treatment of pyriform sinus fistula in neonates is safe and effective. Key words: Newborns; Pyriform sinus fistula; Cysts
