Bronchoscopic dilation techniques and topical application of mitomycin-C in the treatment of tracheal stenosis post intubation - Two case reports [Técnicas de dilatação broncoscópica e aplicação tópica de mitomicina C no tratamento da estenose traqueal pós-entubação - A propósito de dois casos clínicos]

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.
