Endoscopic treatment of acquired subglottic stenosis in children: Predictors of success.

Subglottic stenosis is a congenital or acquired disease characterized by the narrowing of the airways, from the vocal cords to the lower border of the cricoid cartilage. It is one of the main causes of stridor and respiratory distress in children. More than 90 % of laryngeal stenoses are acquired due to prolonged endotracheal intubation. The pediatric management of subglottic stenosis is complex and may be affected by different factors that have an impact on the final outcome. Treatment may involve endoscopic procedures and/or open surgeries. Here we describe our experience in 35 patients with acquired subglottic stenosis who underwent endoscopic treatment with rigid dilation and identify the potential predictors of success of this technique.
