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 ar-ytenoidectomy 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 Surger-y,West China Hospital of Sichuan University,from Jan.2019 to Dec.2023.Preoperative and postoperative eval-uations 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 im-prove respiratory difficulty despite its impact on voice quality,with no significant impairment to swallowing func-tion,shows significant clinical value.
