Abstract
A case of piriform sinus fistula is presented. The patient was a 38-year-old male. His main clinical symptom was recurrent cervical swelling. This case was diagnosed based on flororadiography with barium. Prior to performing a fistulectomy, we put pioctanin in the fistula, and left a Fogarty catheter in the fistula. Subsequently, a fistulectomy with a hemithyroidectomy of the left lobe was performed with those guides. The patients neck abscess has not recurred since the operation.
