MERALDI, Ana et al. Estenosis subglótica idiopática, reporte de un caso. Rev. am. med. respir. [online]. 2014, vol.14, n.3, pp.323-327. ISSN 1852-236X.

Idiopathic subglottic stenosis is a narrowing of the larynx at the cricoid cartilage level with unknown etiology. There are multiple causes, but its etiology can be mainly divided into traumatic and non traumatic stenosis. It is a rare condition for which the real incidence has never been established due to the difficulty of making the diagnosis. There is a preponderance of young females affected between 30-40 years old. Its development in adult patients shows clinical signs such as stridor and progressive dyspnea. The diagnosis is established by the histological study. All the other causes of tracheal stenosis should be excluded before initiating the appropriate treatment. The tracheal stenosis is managed by means of endobronchial laser therapy, laryngotracheal reconstruction or bronchoscopic dilatation. We present a case of a young woman with stridor as the only symptom and a final diagnosis of idiopathic subglottic stenosis. The literature is reviewed.
