OBJECTIVES: We report outcomes of balloon dilation in the endoscopic management of pediatric subglottic stenosis (SGS) and discuss the role of balloon dilation in both primary and adjuvant therapy. METHODS: We performed a retrospective review of treatment with noncompliant, high-pressure balloons for SGS in the past 2 years at a tertiary pediatric hospital. Fifty-one dilations were performed in 28 children with SGS. The children's mean age was 42 months. The mean SGS grade was 2.46. RESULTS: Fifteen children had primary balloon dilation, and 13 had adjuvant balloon dilation. Overall, 16 children (57.1%) had successful balloon dilation. Of those who underwent primary dilation, 9 (60.0%) were able to avoid open reconstruction or tracheotomy and 6 had their symptoms temporarily improved (average, 36 days) until definitive open reconstruction. Of the patients who underwent adjuvant dilation, 7 (53.8%) were successfully decannulated. Nine of the 12 failed balloon dilations were in children who had concomitant airway disorders; in contrast, only 6 of 16 children in whom treatment was successful had concomitant airway disorders (p = 0.048). There was no statistical association between successful versus failed treatment and age (51.6 versus 27.9 months; p = 0.23), degree of stenosis (grade 2.3 versus grade 2.6; p = 0.41), presence of lung disease (33.3% versus 70%; p = 0.07), or soft versus firm stenosis (60.0% versus 53.1%; p = 0.71). CONCLUSIONS: Balloon dilation plays an important role in the primary and adjuvant management of pediatric SGS. The presence of concomitant airway lesions is significantly associated with failure of balloon dilation treatment. Meticulous surveillance of the dilated airway is necessary, given this failure rate.
