Objectives. Balloon dilation
laryngoplasty has been suggested as an alternative treatment to open surgical treatment of
acquired subglottic stenosis in children. We describe long-term outcomes of balloon dilation for
acquired subglottic stenosis in children. Methods. The medical charts of children who had balloon dilation for subglottic
stenosis secondary to intubation were reviewed. Data included demographics, relevant history and physical examination, diagnostic workup, and management. Outcomes of balloon dilation were assessed based on improvement in preoperative symptoms, grading of
stenosis, complications, and need for additional procedures. Results. Three children (2 male, 1 female, age range: 14 weeks-1 year) underwent balloon dilation for
acquired subglottic stenosis. Patients presented with
stridor and increased work of breathing. Duration of intubation ranged from 2 days to 3 weeks. Patients became symptomatic 5 days to 6 weeks after extubation. Grade of subglottic
stenosis was II in 2 patients and III in one. Subglottic
stenosis patients had 2-3 dilations within 2-10 weeks. All patients were asymptomatic during 14-21-month follow-up. Conclusions. Serial balloon dilation was safe and successful method to manage
acquired subglottic stenosis in this group of children. No recurrence was noted in a follow-up more than a year after resolution of symptoms.
