• We developed a canine animal model of subglottic stenosis following prolonged intubation with modified noncuffed endotracheal tubes. None of the puppies intubated for seven days had an irreversible stenosing subglottic lesion, whereas all animals intubated for 14 days or more had at least a 40% to 50% reduction of the subglottic lumen secondary to maturing fibrotic stenosis. The model described is more congruent with the known and suspected pathogenesis in those infants and children who require prolonged endotracheal intubation and subsequently acquire subglottic stenosis, and can be used in evaluating the efficacy of medical therapy or surgical therapy, or both, in the prevention or management of this disease.
