- Abstract: OBJECTIVES: The purpose of this study was to assess the long-term results of endoscopic dilatation of airway stenosis and to evaluate predictive factors for favorable results. METHODS: Fifty-four patients with tracheal and subglottic stenosis who underwent endoscopic dilatation with at least 12 months follow-up were enrolled in this study. We evaluated predictive factors for final treatment outcome such as stenosis length, location, characteristics, procedure type, and the severity of stenosis. RESULTS: The final outcome of endoscopic dilatation showed a cure rate of 40.7%, improvement rate of 46.3%, and failure rate of 13.0%. Patients with mild stenosis or a shorter stenotic segment and those who underwent a touch-up procedure following tracheal resection with end-to-end anastomosis showed better outcomes. The cure rate of endoscopic dilatation for patients with shorter mild stenosis was 72.2%. CONCLUSION: Endoscopic dilatation may be a primary treatment modality for patients with airway stenosis characterized by mild severity and a short stenotic segment.
