Abstract

Objectives: Subglottic stenosis is an abnormal narrowing of the tracheal lumen at the level of subglottis (the area in between the vocal cords and the cricoid cartilage). It can cause significant symptoms due to severe attenuation of airflow. We describe our experience in alleviating symptoms by addressing the stenosis using fibreoptic bronchoscopic methods. Methods: We report all concurrent cases performed between September 2015 and July 2016. We use a combination of balloon dilation, electro-surgery knife to dilate and incise stenotic segments followed by steroid injection to modulate healing. Results: We treated 10 patients in the study period, 8 of which were women. A total of 39 procedures were performed on these patients during this period. Gastro-esophageal reflux was the most common comorbidity associated with stenosis. The majority of the patients required more than 2 therapeutic procedures, but none required more than 4 procedures. There were no complications. Conclusion: Tracheal stenosis and in particular subglottic stenosis is a recurrent process and its management requires extensive collaboration amongst treating specialties. Our technique of steroid injection after dilation of the stenosis was effective in symptom control and decreased the number of repeat procedures.
