Endoscopic Mucosal Injection Versus Ultrasound-Guided Injection of Triamcinolone to Treat Subglottic Stenosis

This study employs a multicenter, randomized controlled trial method, where patients meeting the inclusion criteria for subglottic stenosis are randomly divided into two groups. These groups are respectively undergoing translaryngeal endoscopic mucosal injection and ultrasound-guided injection of triamcinolone treatment. The comparison will focus on various indicators such as therapeutic effect, incidence of adverse reactions, treatment costs, and hospital resource utilization between the two groups. The safety and effectiveness will be compared to determine the relative merits of the two treatment methods.
