Restoring glottic mobility in PGS is a major challenge. In orthopedic and plastic surgery, post\u2010operative physical therapy is associated with improved motion range and flexibility; yet, this principle was never applied to laryngeal surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective cohort of PGS adult patients, treated by the DISCO protocol during 2018\u20132020. DISCO involves the following: scar release, glottic dilation, and steroid injection, followed by post\u2010operative cough as glottic physical therapy. Maximal glottic opening angle (MGOA), relative glottic opening area (RGOA), and relative glottic insufficiency area (RGIA) were calculated before and post\u2010operatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seventeen patients were included; PGS etiology was post\u2010intubation (<jats:italic>n<\/jats:italic>\u00a0=\u00a010), post\u2010irradiation (<jats:italic>n<\/jats:italic>\u00a0=\u00a03), both (<jats:italic>n<\/jats:italic>\u00a0=\u00a01) and joint sclerosis (<jats:italic>n<\/jats:italic>\u00a0=\u00a03). Six patients also had additional airway disorders. Sixteen patients were tracheostomy\u2010dependent. 2 (12%), 8 (47%) and 7 (41%) patients had type II, III and IV stenosis, respectively. Surgery included scar release, dilation and steroid injection alone in 7 patients; and additional unilateral sub\u2010mucosal arytenoidectomy in 10. The mean follow\u2010up was 17.5\u2009months. There were no major complications. Successful outcomes (e.g., decannulation or permanent capping) were achieved in 14 (82%) patients with some restoration of joint movement. None had a persistent voice or swallowing complaints. Both MGOA and RGOA increased in all patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
