Abstract
In the past 6 years, 40 children underwent surgery for laryngotracheal stenosis; 32 by the external approach and 8 by endoscopic CO 2 laser. Twenty-seven children (67%) were less than 5 years old at the time 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 [< 70%, n = 8], and treatment by external surgical methods for grade II [70% to 90%, n = 13], grade III [90% to 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.
