Abstract

A short length of oversize endotracheal tube was sutured in the undamaged subglottis of 22 rabbits to explore the effect of laryngeal stents. The stent was secured to lie beneath the vocal cords. The histologic changes were minimal irrespective of the type of tube used and how long it remained in situ. These findings are consistent with the theory that tube movement is necessary to produce stenosis and are encouraging given the widespread use of stents in pediatric laryngeal reconstruction. The role of gastric acid in producing subglottic stenosis is discussed.
