摘要
idiopathic tracheal stenosis is uncommon. herein, we report four cases, all presenting a similar clinical profile: diagnosed through bronchoscopy and having a history of being treated unsuccessfully for bronchospasm. three of the patients were treated with dilatation and an oral corticosteroid. one of those three underwent tracheoplasty. in the remaining patient, the stenosis was more extensive (2 cm, with a 70% reduction in the size of the lumen), and dilatation was not an option. therefore, that patient underwent laryngotracheal resection. in all four patients, the evolution was favorable. idiopathic tracheal stenosis should be contemplated in cases of ˋbronchitisˋ that are not resolved using conventional treatments. bronchoscopy and dilatation have provided satisfactory results. occasionally, laryngotracheal reconstruction is necessary.
