Glottic stenosis is a discrete cause of airway compromise. We aimed to determine the surgical outcomes of transverse cordotomy with anteromedial arytenoidectomy (TCAMA), performed in the setting of isolated glottic stenosis resulting from two discrete etiologies: bilateral vocal fold paralysis (BVFP) and posterior glottic stenosis (PGS).Retrospective, analytic cohort study.Twenty-six patients with isolated glottic stenosis were treated with TCAMA between 2006 and 2019. A retrospective analysis determined decannulation rates and intervals, voice outcomes, swallowing outcomes, and reoperation rates postoperatively. Outcomes between the two etiologic cohorts were compared.Of the 26 patients, 16/26 patients were diagnosed with PGS and 10/26 with BVFP. Eighteen patients required tracheotomies during their clinical course (11/16 PGS, and 7/10 BVFP), and 100% were ultimately decannulated. The PGS cohort required two-sided interventions more frequently than the BVFP cohort (45.5% vs. 0%, P = .066). Trach-dependent PGS patients required a longer time to achieve decannulation than BVFP patients by a factor of 2.38, although the difference was not statistically significant (102.3 days vs. 42.9 days, respectively, P = .113). Patients demonstrated a significant change in maximum phonation time but no statistically significant differences with preoperative versus postoperative voice outcomes like voice-related quality of life. All patients ultimately returned to their baseline swallow function postoperatively.TCAMA is an effective treatment for surgical rehabilitation of glottic stenosis caused by both BVFP and PGS. Patient-reported outcomes of postoperative vocal function remain consistent following surgical intervention. Additional, prospective studies with greater power are warranted to validate the contrasting outcomes observed when applying this discrete surgical technique across two distinct diagnostic cohorts in this retrospective study.4.
