Acquired Subglottic Stenosis in Children

Abstract

Subglottic stenosis is a disorder characterized by narrowing of the airway below the glottis or apposing edges of the true vocal cords. In a broad definition, the term may be used to describe airway compromise in the regions of the larynx or the trachea or both. In children, the stenosis is usually due to scar formation secondary to prolonged airway intubation, rather than to external trauma. The location and extent of the stenosis are highly variable; consequently, corrective measures need to be selected to suit the individual problem. In the present series of children, conservative treatment was adequate for lesser degrees of stenosis; those with more severe scarring required external laryngeal surgery. The preoperative evaluation and treatment plans are reviewed.
