Abstract

Voice is a physical phenomenon, generated by vocal fold and expiratory airflow. Dysphonia should come from abnormal vocal fold and airflow. Occassionally larynx looks normal in show, but it is actually not. There should be undetected structural or functional abnormalities. So when ENT doctors face dysphonia patients who looks normal larynx, should make a diagnosis through close observation. In this review article we present some dysphonia diseases which looks normal larynx. For example vocal fatigue, vocal fold paresis, posterior glottic diastasis, muscle tension dysphonia and psychogenic dysphonia.
