[Study on the efficacy of posterior cordotomy with partial arytenoidectomy in bilateral vocal fold paralysis].

Objective: The aim of this study is to investigate the efficacy of posterior cordotomy with partial arytenoidectomy in bilateral vocal fold paralysis（BVFP）. Methods: Medical records of 37 patients with BVFP were retrospectively collected, and they were all admitted to the Department of Otolaryngology-Head and Neck Surgery, West China Hospital of Sichuan University, from Jan. 2019 to Dec. 2023. Preoperative and postoperative evaluations of respiratory function, voice quality, and swallowing function were conducted. Results: Postoperatively, 32 out of 37 patients achieved significant relief in breathing difficulties. Out of 29 patients with tracheostomy, 26（89.7%） were successfully decannulated. One month postoperative follow-up revealed a decline in voice quality for 33 patients（89.2%）, and 5 cases（13.5%） reported a decrease in swallowing function. However, by three months postoperatively, both voice quality and swallowing function showed significant improvement. Conclusion: Posterior cordotomy with partial arytenoidectomy is an effective surgical method for BVFP, and significantly improve respiratory difficulty despite its impact on voice quality, with no significant impairment to swallowing function, shows significant clinical value.
