Laryngotracheal Reconstruction for Subglottic Stenosis

Abstract

Laryngotracheal reconstruction (LTR) has been employed for the treatment of severe laryngotracheal stenosis for the past 6 years at Johns Hopkins Hospital. Thirty-one children underwent LTR with costal cartilage grafting, 24 of whom had Aboulker stents placed. Short stents were used in 22 patients. Six patients received definitive treatment in a single-stage LTR; 1 child had no stent placed. Twenty-six (84%) of the 31 patients were decannulated. It was concluded that decannulation can be obtained in selected patients with the short Aboulker stent or single-stage LTR. A new classification system for laryngotracheal stenosis, based on objective measurements and the separate analysis of posterior glottic fibrosis, was developed. The proposed classification system allows recommendations for treatment. Moreover, it can be easily reproduced and may facilitate comparison of results.
