[Failures of surgical treatment of iatrogenic laryngotracheal stenosis (author's transl)].

In the light of their experience involving almost 100 cases, the authors emphasize the most frequent causes of failure of the surgical treatment of laryngotracheal stenosis. Minimal procedures most including a combination of the two procedures of widening of the laryngeal lumen and conservation of this recalibration by an atraumatic tube, axial and well tolerated, run the risk of giving results which, if not poor, will be at least incomplete. The classical operation of Rethi would appear to be inadequate to ensure totally effective recalibration if stenosis is major and methods of anterior widening of the larynx, associated with the Rethi procedure or not, are more widely indicated.
