[Management of subglottic stenosis in children with endoscopic balloon dilation].
OBJECTIVE
To evaluate the efficacy of endoscopic balloon dilation for subglottic stenosis.


METHODS
The clinical outcomes of 9 pediatric patients treated with balloon dilation were retrospectively analyzed. There were 8 male and 1 female. Their age ranged from 7 months to 7 years (mean 2.5 years). The degree of stenosis was classified according to Myer-Cotton classification as follows: grade Ⅱ (n=7) and grade Ⅲ (n=2). The causes of the stenosis were postintubation lesions (n=8) and laryngeal penetrating trauma (n=1).


RESULTS
The patients had undergone 1 to 3 dilations with an average of 1.8 procedures per patient. Six (66.7%) patients were decannulated. Among them, 4(44.4%) were decannulated after one dilation procedure. Pneumothoraces occurred in 2 children postoperatively.


CONCLUSIONS
Endoscopic balloon dilation is an effective, relatively safe and minimally invasive surgical method for patients with low-grade subglottic stenosis.
