[Iatrogenic laryngotracheal stenosis. Our therapeutic experience apropos of 25 cases].

The authors report 25 cases of iatrogenous laryngotracheal stenosis seen at the university hospital IBN Rochd of Casablanca these stenosis are frequent as well as in infant as (12 cases) as in males (10 cases) they are the consequence of prolonged intubation in cases of coma (12 cases) of traumatic intubation (10 cases) but also after laryngeal irradiation (2 cases) or partial laryngeal surgery (1 case). The seat of stenosis is laryngeal (56%) laryngotracheal (36%) and tracheal (8%). The treatment of these stenosis is difficult; our patients are usually tracheotomised (63.6%) with extensive stenosis. The treatment has used this rilling with laser (12 cases) an endoscopic microsurgery (4 cases) and open surgery 2 times. The dilatation by mean of Montgomery tube or by Traissac tube is often irispensable to avoid relapses. The results are favorable in spite of the length of the treatment (10 days to 30 months) with 15 succesS and 7 partial failures. The authors underline the stenagenous risk of intubations and tracheotomies and on the rules to prevent these iatrogenous laryngo-tracheal stenosis.
