Comparative StudyFlexible laryngoscopy in neonates, infants, and young children.
Flexible laryngoscopy was performed 453 times on 264 patients 4 years of age or younger. Sixty-five percent were under 6 months of age. Stridor was the indication for laryngoscopy in 60% of the patients. ⋯ The most common finding was laryngomalacia, followed by laryngeal edema, normal larynges, and vocal cord paralysis or paresis. Subglottic stenosis was diagnosed in 17 patients. Flexible laryngoscopy is a relatively noninvasive, safe, and effective technique for examining the larynx of infants and young children.

Subglottic stenosis is more likely to develop secondary to endotracheal intubation if one or more trauma-related risk factors are involved. Ulcerations occur most often in the posterior-lateral cricoid ring. They vary in size and may involve the entire circumference of the subglottic area. The ulcerations heal with fibrous scarring which, if extensive enough, results in subglottic stenosis.
