Abstract

In order to keep a record of stroboscopic images, we developed a video-tape recording system. This system can be utilized in the following manners:<br>(1) The physician can use not only verbal but also visual means of explanation of the patient's laryngeal condition.<br>(2) Teaching the various aspects of vocal fold vibration can be enhanced with the use of this dynamic method.<br>(3) More accurate information can be gleaned by allowing for more than one specialist to view the vocal fold in motion at the same time. In addition, this system permits repeated viewings at convenient times.<br>(4) One can compare vibratory patterns between different time points, including pre- and post-therapeutic examinations.<br>We also developed an additional system with which any waveforms displayed on an oscilloscope can be superimposed on the stroboscopic images.
