RESUMEN
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 bronchitis that are not resolved using conventional treatments. Bronchoscopy and dilatation have provided satisfactory results. Occasionally, laryngotracheal reconstruction is necessary.

A estenose idiopática de traquéia é incomum. Relatam-se quatro casos com quadro clínico semelhante: história de tratamento de broncoespasmo sem resultado e diagnóstico por broncoscopia. O tratamento em três pacientes foi dilatação e corticóide sistêmico; em um realizou-se traqueoplastia. No quarto, a estenose era mais extensa (2 cm) com redução da luz de 70 por cento, sem possibilidade de dilatação. Realizou-se ressecção laringo-traqueal. Todos apresentaram boa evolução. A estenose idiopática de traquéia deve ser cogitada em casos de "bronquite" mal resolvida com tratamentos convencionais. A broncoscopia e a dilatação têm apresentado bons resultados. Eventualmente, torna-se necessária ressecção laringo-traqueal.
