The purpose of this study is to evaluate the results of endoscopic posterior cordotomy using microdissection electrodes in patients with bilateral vocal cord paralysis. Eleven patients underwent endoscopic posterior cordotomy using a radiofrequency Arrowtip monopolar needle. Preoperative-postoperative exercise tolerance, airway, and voice evaluation were performed in all patients. Two patients required a secondary revision operation due to granulation and crust formation and respiratory problems. No other complications were encountered. Two patients with tracheotomy cannulas were decannulated on the third postoperative day. All patients had an adequate functional airway and good exercise tolerance compared with poor preoperative exercise tolerance. There was no significant difference between preoperative and postoperative Voice Handicap Index values (P > .05). The data indicated the safety, easy use, and efficiency of the microdissection radiofrequency electrodes in patients with bilateral vocal fold paralysis. This technique provides a reliable alternative to laser procedures.
