[Cicatricial stenosis in the crico-tracheal region. A new surgical approach].

Nearly a half of laryngo-tracheal cicatrical stenoses following long-term intubation are found at the level of the cricoid cartilage. Early and correctly-performed tracheotomy can prevent this complication in almost all cases. The best results of surgical treatment can be expected after transverse partial resection of cricoid and upper trachea or after Réthi's laminotomy. In 14 patients after cricotomy a bone graft from the manubrium sterni was inserted, to separate permanently the free borders of the divided cricoid cartilage. Operative technics and the results of treatment are presented.
