Researchers continue to look for an improved animal model for the study of acquired subglottic stenosis. This report describes a ferret model that reliably produces 40% to 60% stenosis with a method analogous to the pathophysiology of prolonged endotracheal intubation. Unlike some previously developed animal models, this model has a low morbidity and a perioperative mortality of less than 5%. Ferrets are small, hardy animals that are inexpensive and easy to house, handle, and anesthetize. They are readily available from breeders in a uniform size, age, and sex. Their airway is disproportionately large for their body size, making them particularly well suited for the study of acquired subglottic stenosis and subsequent surgical therapy.
