The patient proceeded to laser division of the glottic web and subglottic stenosis along with balloon dilatation of the subglottic stenosis. Biopsies of the glottis and subglottis were also taken to further investigate the cause.
Upon extubation, the patient's breathing was much improved. Subsequent investigations for autoimmune laryngeal pathology were unremarkable and the histopathology revealed essentially scar tissue.
