Background: There are many causes for vocal cord paralysis, which can cause difficulty in breathing in serious cases. The common surgical methods for solving vocal cord paralysis include laryngeal splitting or laser surgery, but there are limitations. Plasma radiofrequency ablation is a new treatment with good achievements in clinical applications. Objective: To investigate the effect of coblation-assisted arytenoidectomy (CSA) in the treatment of bilateral vocal cord paralysis (BVCP). Methods: All patients had undergone preoperative electrolaryngoscopic examination of the glottidis rima; electronic laryngoscopy can assess the width of the glottis. The purpose of preoperative electronic laryngoscopic evaluation is to assess the width of the glottis, and arytenoid cartilage movement. Unilateral arytenoid cartilage and a section of the vocal cords were removed in all cases. Results: Of the 14 patients, 13 were successfully extubated after CSA; 1 patient could not be extubated and underwent a second CSA of the contralateral arytenoid cartilage, after which extubation was achieved. All patients were continuously followed up (6 months to 2 years), and all achieved satisfactory results. Conclusions and significance: CSA can effectively relieve post-CSA dyspnea in patients with BVCP. More patients underwent tracheal cannula extubation after tracheotomy compared with other surgeries.
