[Glottic measurement and vocal evaluation after three surgical techniques in the treatment of bilateral vocal cord paralysis].

Objective: To evaluate postoperative glottic area and vocal quality of three various surgical techniques for treating bilateral vocal cord paralysis, including laser arytenoidectomy (Group A, 24 cases), reinnervation of the posterior cricoarytenoid muscle by phrenic nerve (Group B, 9 cases) and arytenoidectomy accompanying lateral cordopexy by extralaryngeal approach (Woodman's procedure, Group C, 13 cases).

Methods: 46 cases suffered from bilateral recurrent laryngeal nerve injury were included in our study. The pre-postoperative glottic measurement and vocal acoustic parameters were analyzed.
