Abstract
It is well known that hoarse voice can be produced during the course of any laryngeal lesion. One possible cause is recurrent nerve paralysis due to various pathological conditions. Among various etiologies, our clinical statistics indicate that the incidence of hoarseness due to mediastinal pathology is 2.6%. As for treatment, glottal incompetence should be corrected and various methods have been proposed for this purpose. From our experience, arytenoid rotation and intracordal injection give the best results. However indication for each technique should be considered carefully.
