Experience of diagnosis and treatment for congenital pyriform sinus fistula / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

Objective@#To evaluate the imaging features, clinical presentation, operative methods complication and the surgical outcomes of the congenital pyriform sinus fistula(CPSF). @*Methods@#The clinical data of 185 patients with CPSF treated from January 2013 to October 2017 at the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively. @*Results@#The lesions were predominantly on the left side(170/185). Among 185 cases, 146 cases received endoscopic coblation cauterization, 27 cases had traditional open surgery, 8 cases underwent endoscopic coblation cauterization plus traditional open surgery, 2 cases for endoscopic chemocauterization, and 2 cases for endoscopic electrosection. Twenty-eight cases recurred, with a recurrence rate of 15.1%. Postoperative hoarseness occurred in 22 cases, disappeared within 0.5-6.0 months later. @*Conclusions@#Patients with a history of recurrent cervical abscess should be highly suspect the existence of CPSF. Endoscopic coblation cauterization is a kind of surgical method with minimal injury, with low recurrence rate and low operative risk.
