Perioperative Factors Aggravating Pharyngocutaneous Fistula After Total Laryngectomy: A Single-Center Retrospective Analysis Using the Clavien-Dindo Classification.

Background: Pharyngocutaneous fistula formation represents a major postoperative complication following total laryngectomy. We aimed to investigate the risk factors for pharyngocutaneous fistula development after total laryngectomy and to identify factors that lead to severe cases of pharyngocutaneous fistula.

Methods: Patients who underwent total laryngectomy between January 2013 and February 2021 were included in the study and were divided into 2 groups: Those with and without pharyngocutaneous fistula.
