[Idiopathic sub-glottal stenosis in the adult].

Idiopathic subglottic stenosis is a rare condition. The records of five patients with idiopathic subglottic stenosis treated between 1989 and 1998 were reviewed. All were female and had similar clinical and histopathologic features. Endoscopic dilatation or/and radial CO2 laser and dilatation were successful in maintaining the airway of all five patients without tracheotomy. The pathogenesis of idiopathic subglottic stenosis is strictly speculative, for this reason we advocate a conservative approach.
