In the past 6 years, 40 children underwent surgery for laryngotracheal stenosis; 32 by the external approach, 8 by endoscopic CO2 laser. Twenty-seven children (67%) were less than 5 years old at the moment of treatment and 80% of the stenoses (n = 32) corresponded to an etiology that is secondary to endotracheal intubation and/or tracheotomy. By grading the stenoses according to the amount of narrowing of the lumen, the authors emphasize the interest of conservative treatment (endoscopic) for grade I (less than 70%, n = 8), and treatment by external surgical methods for grade II (70%-90%, n = 13), grade III (90%-99%, n = 14), and grade IV (total obstruction, n = 5). At this time, the most commonly used technique is laryngotracheoplasty with costal cartilage interposition. In this series, 88% of the patients were successfully decannulated. As for the treatment of stenosis in infants, the authors describe their recent experience of laryngotracheofissure in 7 patients as an alternative to either tracheotomy in cases of difficult extubation or laryngotracheoplasty when the child is underweight.
