PURPOSE: The aim of the study is to determine the predisposing factors for pharyngocutaneous fistula (PCF) in patients undergoing total laryngectomy (TL) or extended TL and, secondarily, to propose a new severity-based classification system.
METHODS: This is a retrospective study of 400 patients who underwent TL or extended TL. Major fistula was defined as a fistula (1) persisting for ≥ 4 weeks, (2) requiring surgical treatment, or (3) associated with perioperative mortality.
RESULTS: PCF formation occurred in 93 patients (23.3%) and major fistula in 72 (18.0%). Extended surgery with partial or total pharyngectomy, previous treatment with radiotherapy, and postoperative hemoglobin levels < 99 g/L were associated with a significantly higher risk of developing major fistula.
CONCLUSIONS: We propose a new PCF classification system according to clinical severity. Predictors of major fistula were the type of surgery, previous radiotherapy, and low (< 99 g/L) postoperative hemoglobin levels. We consider the use of onlay flaps in irradiated patients who require partial pharyngectomy.
