Objectives:To describe our experience and provide guidelines for maximum safe balloon sizes according to age in children undergoing balloon dilatation.Method:A retrospective review was conducted of children undergoing balloon dilatation for subglottic stenosis in a paediatric tertiary unit between May 2006 and February 2016.Results:A total of 166 patients underwent balloon dilatation. Mean ( ± standard deviation) patient age was 4.5 ± 3.99 years. The median balloon size was 8 mm, the median balloon inflation pressure was 10 atm, and the mean balloon inflation time was 65.1 ± 18.6 seconds. No significant unexpected events occurred. The Pearson correlation co-efficient for the relationship between patient age and balloon size was 0.85 (p = 0.001), suggesting a strongly positive correlation.Conclusion:This study demonstrated that balloon dilatation is a safe procedure for airway stenosis. The results suggest using a balloon diameter that is equal to the outer diameter of the age-appropriate endotracheal tube +1 mm for the larynx and subglottis and +2 mm for the trachea.
