Abstract

Objectives: Develop a diagnostic procedure for pyriform sinus fistula (PSF), including definitive and differential diagnosis. Material and methods: A descriptive study on a cluster of 60 patients with a confirmed diagnosis of PSF and treated at the Hanoi National Otorhinolaryngology Hospital from January 2020 to August 2022. Results: 27 men and 33 women from 2 to 56 years old (mean: 17.2 ± 13.59), of which 65.0 % were recurrent episodes. The clinical symptoms were abundant, including: fever (61.7%) neck pain (83.3%), purulent discharge (10.0%), inflammation/abscess of the lateral neck (58.3%) or fistula in the lateral neck area. Endoscopy of the hypopharynx and piryform sinus cavity showed fistulas mainly at the fundus (88.3%) and on the left side (85.0%). Conclusion: Diagnosis of PSF requires a combination of clinical and paraclinical investigations, the most important of which is hypopharyngeal endoscopic to find the fistula.
