Resumo
A estenose traqueal surge na sequência de agressões à mucosa traqueal (isquémicas, traumáticas ou outras). O tratamento das estenoses traqueais continua a representar um desafio em termos de técnicas endoscópicas e cirurgia, apesar de todos os recentes avanços nesta área. O processo de cicatrização e a reestenose são as principais causas de falência terapêutica.
Os autores apresentam dois casos clínicos de doentes com estenose traqueal como consequência de entubação orotraqueal prolongada/traqueostomia, em que o tratamento foi bem sucedido com dilatação com broncoscopia rígida e laser, complementada por aplicação tópica de mitomicina C.

Abstract
Tracheal stenosis follows any injury to the airway mucosa, such as ischaemic, traumatic and other injuries.
The treatment of tracheal stenosis remains a challenging problem despite all the advances in endoscopic and surgical techniques. Scar formation and reestenosis are the main causes of treatment failure.
The authors present two cases of successful treatment of a tracheal stenosis after tracheal injury from prolonged oro-tracheal intubation / tracheostomy following dilatation with rigid broncoscope and laser therapy, associated with topical application of mitomycin C as an adjuvant treatment.
