Repair of Posterior Glottic Stenosis with the Modified Endoscopic Postcricoid Advancement Flap

Posterior glottic stenosis is a difficult clinical problem that frequently results in bilateral vocal fold immobility, dyspnea, and tracheostomy dependence. Charts were reviewed of all patients undergoing a modified endoscopic postcricoid advancement flap procedure for posterior glottic stenosis between October 1, 2003, and June 30, 2015. Age, sex, operative findings, complications, and outcomes were noted. Follow-up was available in 10 of 11 patients, 10 of whom were successfully decannulated. There were no complications. Regular diet was maintained in all patients. In patients with bilateral vocal fold immobility secondary to posterior glottis stenosis, endoscopic repair via endoscopic postcricoid advancement flap can restore full vocal fold motion and allow decannulation. In select patients with posterior glottic stenosis, repair via endoscopic postcricoid advancement flap should be considered in lieu of ablative methods, such as cordotomy, cordectomy, or arytenoidectomy.
