[Functional assessment of posterior cordotomy in patients with bilateral vocal fold paralysis].

Unlabelled: Surgical treatment of bilateral vocal fold paralysis must be undertaken if such a condition lasts 6-12 months or longer and causes dyspnoea. The purpose of the procedures is to assure proper airflow through the glottis and to preserve good voice and unimpaired swallowing. Modern endoscopic surgery of the glottis is performed with CO2 laser.
