Office-Based Steroid Injection in Subglottic Stenosis
摘要
Subglottic stenosis (SGS) is a form of partial or complete narrowing of the laryngeal airway [1]. The stenotic segment is in the subglottic region but may extend caudally to the trachea, resulting in laryngotracheal stenosis. The stenosis may also extend cephalically to the glottis, leading to narrowing of the glottic aperture with or without impairment in the mobility of the vocal folds. Subglottic stenosis accounts for 50% of laryngotracheal stenosis, the prevalence of which is 1 in 200,000 adults [2, 3]. Affected patients invariably present with respiratory complaints that are falsely ascribed to diseases of the lower airway. The most commonly reported symptoms are dyspnea, wheezing, cough, and stridor. In severe cases, patients may present with respiratory distress—necessitating a tracheotomy to secure the airway.
