Abstract

A rare complication of prolonged intubation or laryngeal radiation is destruction of the posterior cricoid cartilage with resultant hypopharyngeal-subglottic fistula leading to aspiration and inability to consume a regular diet. We describe a step-by-step endoscopic approach to the closure of a hypopharyngeal-subglottic fistula. This technique successfully closed the fistula in two patients and allowed the safe resumption of an oral diet.
