Post Intubation Phonatory Insufficiency: A novel surgical treatment

Abstract

Post Intubation Phonatory Insufficiency as a result of prolonged intubation in premature neonates is a challenging condition to diagnose and treat.An endotracheal tube can cause an erosive injury to the medial surface of the arytenoid cartilage resulting in a permanent divot or gap in the posterior glottis between the arytenoid and the vocal ligament and cord.There have been many treatments proposed and performed for posterior glottic insufficiency.We describe a novel surgical approach to address this problem in two adolescents with severe breathy dysphonia and have had promising results.
