Surgical Indication of Fistulectomy with Transcervical Excision for Pyriform Sinus Fistula

Abstract

Pyriform sinus fistula is one of the causes of deep neck abscess during childhood. Treatment typically involves treatment of the inflammation followed by fistula removal via an external incision or the intra-oral route. In this manuscript, we report two cases that made satisfactory progress after successful identification and extraction of the fistula tract via an external incision during both inflammatory and non-inflammatory stages. Additionally, we discuss the indications and optimal timing for surgical treatment. In patients with a neck abscess that requires external incision and drainage, in which a pyriform sinus fistula is the suspected cause, it is important to verify the fistulous tract intraoperatively before proceeding with the surgery.
