Balloon Laryngoplasty for Pediatric Laryngeal Stenosis: Experience in 18 Cases
Introduction: Acquired airway stenosis is a common complication in children after periods of tracheal intubation. Over the past decade, there has also been renewed interest in serial dilatation for the management of subglottic stenosis (SGS) with the advent of new technologies such as airway balloons designed for the pediatric airway. We reviewed our experience in balloon laryngoplasty (BLP) for the treatment of these lesions.
Objectives: The study aimed to present the experience of a tertiary-care hospital with BLP in children with acute SGS.
Materials and Methods: We performed a prospective study of patients who presented with acute SGS (those with granulation tissue) treated at our center from 2009 to 2014. They underwent direct laryngoscopy under general anesthesia and dilatation of the stenotic segment with angioplasty balloon. A second laryngoscopy was performed between 1 and 2 weeks later, except from three children because of bad clinical conditions. Their final stenosis classification was performed soon after the BLP.
Results: Eighteen patients (7 female, 11 male) were included in this study. Grade 3 SGS was identified in 11 children, grade 2 in 6 children, and grade 1 in 1 child. By the final examination, 5 children presented with asymptomatic grade 1 SGS, whereas the other 13 presented with normal airway and remained asymptomatic.
Conclusion: Early endoscopic dilatation with balloon seems to be an effective and safe treatment in acquired acute SGS.
