Recent Advances for Diagnostic Laryngoendoscopic Images of the Vocal Fold Vibration

Abstract

New technology for diagnostic laryngo-endoscopic systems has been developed in the field of laryngology. A computer integrated laryngo-videostroboscope system has been manufactured to precisely visualize vocal fold vibration. Although this system provided distinct slow-motion dynamic images of quasi-periodic vocal fold vibration, aperiodic vibration could not be visualize with laryngo-videostroboscopy. High-speed digital imaging system appears to be useful for this condition. Electronic videoendoscopy with a single-plate RGB sequencing method has also been applied to precisely observe laryngeal lesions; however, the laryngostroboscope cannot connect with this system. Advantages and disadvantages of these systems are discussed here.
