Abstract

Subglottic stenosis (SGS), is a narrowing of the airway below the vocal cords within the cricoid cartilage. SGS affects the pediatric population predominantly, with acquired forms (95% of cases) primarily caused by endotracheal intubation complications, while congenital forms (5%) result from embryologic malformations.

The pediatric airway's unique anatomy makes children particularly vulnerable to obstruction, as the cricoid cartilage represents the narrowest airway point.

SGS severity is classified using the Myer-Cotton grading system (Grades I-IV), with symptoms ranging from exercise-induced stridor in mild cases to life-threatening airway compromise in complete obstruction.

Diagnosis relies on comprehensive history-taking, physical examination, imaging studies, and flexible bronchoscopy as the gold standard.

Management approaches include endoscopic techniques (balloon dilation, laser treatment) for milder cases and open surgical procedures (laryngotracheoplasty, cricotracheal resection) for severe stenosis, with success rates exceeding 90% in specialized centers.

AIM OF THE WORK:

General objective:

To evaluate the association between subglottic stenosis and endotracheal intubation among pediatric age groups diagnosed in the period from 2016 to 2024.
