抄録

Even when the glottal gap is improved by voice recovery surgery, wave-motion failure of the vocal mucosa persists in more than a few patients. In these patients, decreased wave-motion of the vocal mucosa and phase differences between the left and right cords are observed; therefore, it is necessary to evaluate the exact vibrations of the vocal cord in order to perform more precise surgery. The high-speed laryngeal imaging system introduced at our facility can accurately observe vocal cord vibrations even for patients with laryngeal paralysis exhibiting irregular basic frequencies. In this report, the method of image analysis of video obtained from a high-speed imaging system and its reliability are described. In addition, a patient who underwent atelocollagen injection is presented and the usefulness of the system as a clinical approach is discussed.
