Laryngotracheal Lesions in Adults With Long-Term Tracheostomy

Sponsor: Hongying Jiang, MD

Summary

This multicenter prospective observational cohort study will enroll 224 adults with a tracheostomy tube in place for at least 14 days. Within 1 week after enrollment, each participant will undergo a standardized three-station bronchoscopy through the tracheostomy tube and transnasally, with temporary tube occlusion and immediate tube replacement when required. The study will describe the prevalence, anatomic distribution, and severity of laryngotracheal lesions, including mucosal ulceration, scar formation, granulation tissue, vocal cord paralysis, subglottic stenosis, and tracheomalacia. The study will also evaluate clinical and tracheostomy-related factors associated with these lesions. No treatment is assigned by the study; the bronchoscopy is a standardized diagnostic assessment performed for research evaluation.
