Study design: Case Report
Abstract: Idiopathic subglottic and upper tracheal stenosis is an uncommon cause of progressive airway obstruction, predominantly affecting middle-aged women. We report the case of a female patient who presented with progressive stridor at rest over 12 months, without antecedent airway instrumentation or systemic disease. Flexible nasoendoscopy demonstrated irregular subglottic mucosa with airway narrowing, and computed tomography confirmed a 1.5 cm segment of circumferential mucosal thickening resulting in significant luminal compromise. Comprehensive autoimmune screening was negative, supporting an idiopathic aetiology. The patient underwent endoscopic balloon dilatation with adjunctive mucosal trimming, resulting in immediate symptomatic improvement. This case highlights the importance of thorough diagnostic evaluation and minimally invasive management of idiopathic upper tracheal stenosis.
