Acquired stenosis of the upper airway in neonates. An increasing problem.

Abstract

Thirty neonates with acquired airway stenosis were treated between 1975 and 1979 at the C. S. Mott Children's Hospital of the University of Michigan. Neonates surviving a period of ventilation are at risk of developing subglottic stenosis (8.3%). The stenosis is often severe. Children with respiratory distress syndrome and/or neurologic disorders were particularly prone to developing a stenosis (37%). Following treatment, 43% were successfully decannulated and decannulation occurred in a biphasic pattern. Thirty-seven percent were still tracheostomy-dependent but had a voice and were developing normal speech patterns. The mean decannulation time was 92.5 weeks, confirming that acquired subglottic stenosis in the neonate is a serious problem with long-term disability.
