Nutritional predictors of pharyngocutaneous fistula after total laryngectomy: A multivariate analytic study in a single institution.

Objective: The objective of this study was to evaluate, through multivariate analysis, the configuration of nutritional predictors that impact the development pharyngocutaneous fistula (PCF) after total laryngectomy.

Methods: A retrospective cohort study carried out on 203 consecutive patients with laryngeal squamous cell carcinoma who underwent total laryngectomy with neck dissection between June 2015 and June 2020. Patients with risk factors for PCF formation, other than malnutrition, were excluded to eliminate the potential impact of that risk factors on PCF formation and to make the study group homogenous.
