INTRODUCTION: Acquired subglottic stenosis (SGS) occurs in 1-2% of children with a history of intubation. An alternative treatment is endoscopic dilation with rigid dilators.
MATERIAL AND METHODS: Seventy-four patients with SGS grade I to III were treated between 2003 and 2017. Dilations were performed with Hegar-type rigid dilators every 2-3 weeks.
RESULTS: Eighty-two percentage of patients responded to the treatment. 10% presented SGS grade I, 35% grade II and 55% grade III. Previous intubation time in successful cases was 12.4 days and it was 32 days in those that failed (p=0.02). The average number of dilations was 3.23 in the group that responded and 2.98 for those that did not respond (p=0.51). The presence of tracheostomy reduced the effectiveness of the treatment (p=0.002). The average follow-up was 43.5 months.
CONCLUSION: The use of rigid dilators under endoscopic control is an effective minimally invasive method for treating patients with SGS grades I to III. Previous intubation time and the presence of tracheostomy were identified as poor prognostic factors.
