Abstract:
BACKGROUND AND OBJECTIVES: Videostrobokymography (VSK) has been recently developed in our institute. VSK can select multiple regions of interest and analyze vibratory patterns of vocal folds using video data recorded by the conventional videostroboscopy. But the efficacy of VSK in clinical application needs to be proven. MATERIALS AND METHODS: We compared the preoperative and postoperative VSK patterns of Reinke's edema in 15 cases with some other parameters. RESULTS: Most of the patients showed improvement of voice quality by self-assessment, however, the fundamental frequency and subglottic pressure did not return to the normal range after operation. Preoperative videostroboscopy for Reinke's edema patients revealed greatly irregular patterns of mucosal wave so that kymogram could be obtained only in 3 of the 8 preoperative examinations. However, postoperative vibration of the vocal folds returned to the regular pattern on VSK. CONCLUSION: VSK could serve as one of the effective tools to document the vocal fold vibration objectively in various kinds of benign mucosal diseases of the vocal folds.
