Sonographic images of the vocal cords were obtained in 41 healthy human subjects using a phased array realtime ultrasound scanner. The thyroid cartilage provides the acoustic window for sonographic visualization of the vocal cords. The false vocal cords appear as hyperechoic structures, while the true vocal cords are seen as hypoechoic structures. The symmetry of movement of the vocal cords during respiration becomes apparent on examination in real time. Sonography may prove to be a potentially useful technique for the examination of the vocal cords.
