Videostrobokymography (VSK) has been recently developed in our institute. It can select multiple regions of interest and analyze vibratory patterns of vocal folds using video data recorded by conventional videostroboscopy. But its efficacy in clinical application is still unclear. We compared the preoperative and postoperative VSK patterns of Reinke's edema in 15 cases with some other parameters. Most of the patients showed improvement of voice quality by self-assessment, and the vibration of the vocal folds returned to a regular pattern on VSK. However, the fundamental frequency and subglottic pressure did not return to the normal range after operation. Videostrobokymography could be an effective tool for documenting the vocal fold vibration objectively in various kinds of benign mucosal diseases of the vocal folds.
