Abstract
Objective: 1) Understand traditional techniques for the management of supraglottic stenosis. 2) Learn minimally invasive endoscopic technique using CO2 laser pharyngoplasty, balloon dilation, and Mitomycin-C application in the management of supraglottic stenosis.
Method: Case series in a tertiary academic medical center of patients with isolated symptomatic supraglottic stenosis who underwent endoscopic management.
Results: Four patients with symptomatic supraglottic stenosis were initially managed with CO2 laser endoscopic pharyngoplasty, balloon dilation, and topical Mitomycin-C application under general anesthesia. Subsequent management in 3 patients included office-based balloon dilations. Voice, swallowing, and airway outcomes are reviewed with minimum twelve month follow-up. Results were satisfactory in all patients and all were decannulated.
Conclusion: Supraglottic stenosis is a rare entity that has been traditionally managed with supraglottic laryngectomy. However, using minimally invasive endoscopic techniques, long-term success with minimal morbidity can be achieved and should be considered as a first-line management option for this condition.
