Laryngotracheal Reconstruction in Subglottic Stenosis: An Ancient Problem Still Present

Abstract

BACKGROUND: Subglottic stenosis is an ancient but persistent problem as a cause of airway obstruction. The etiology and the results of surgical treatment with thyrotracheal anastomosis were reviewed.

METHODS: Fifty-six patients with subglottic stenosis were studied. All were subjected to laryngotracheal reconstruction by thyrotracheal anastomosis with partial resection of the cricoid.

RESULTS: Of all 56 cases of subglottic stenosis, 48 (86%) had history of previous tracheal intubation, and only 8 (14%) had different non-neoplastic obstructive processes such as scleroma, direct injury, hamartoma, and amyloidosis. Immediate results were good in all cases. After 1 year follow-up, results of thyrotracheal anastomosis were successful in 44 (91%). In 4 other cases a restenosis was observed. Eight patients were lost to follow-up.

CONCLUSIONS: Subglottic stenosis is still frequent after tracheal intubation, but other causes must be considered. Laryngotracheal reconstruction with thyrotracheal anastomosis with partial cricoid resection was feasible with good results in 91% of the cases with follow-up, but this procedure must be performed by a skilled surgical team.
