 The recent development of endoscopes has expanded our ways to observe the hypopharynx. The Sato's curved laryngoscope enabled us to observe the mucosal lesion of pyriform sinus, which was difficult to be observed using previous laryngoscopes.

 Pyriform sinus fistula is a congenital fistula, which causes deep neck infections. Surgical excision is considered to be the definitive therapy, and identifying the fistula opening is essential.

 We presented the case of a 22-year-old woman who was diagnosed with pyriform sinus fistula. We identified the fistula by performing an intraoperative endoscopic examination with the Curved laryngoscope, which ultimately led to a complete excision.
