Abstract

Background:

Treatment of glottic stenosis is a considerable challenge to the otolaryngologist. Glottic airway patency can be compromised by bilateral vocal fold palsy, anterior webbing or a posterior segment scar, which may be significant enough to impair arytenoid movement.

Method:

A retrospective analysis of a prospective database of patients (n = 34) treated by a specialist airway surgeon. All patients underwent endoscopic treatment with a CO2 laser in an attempt to improve airway calibre and, in 12 patients, to decannulate tracheostomy tubes.

Results:

Twenty-one patients had bilateral vocal fold palsy and 13 had predominantly posterior glottic stenosis. A variety of pathology-directed treatment approaches were used to achieve good functional results. Four patients required a second endoscopic procedure. The overall revision rate was 5 per cent for bilateral fold palsy and 23 per cent for posterior glottic stenosis (p < 0.05). All patients had an adequate functional airway calibre, and all 12 tracheotomised patients were decannulated.

Discussion:

Pathology-directed endoscopic laser surgery is safe and effective treatment for glottic stenosis. Rather prescriptive use of unilateral or bilateral cordotomy or combined cordo-arytenoidectomy, clinicians must perform the procedure that will treat the lesion most adequately. Our success rate compared favourably with the best reported results.
