Rigid high-speed laryngoscopy is the state-of-the-art examination technique for the visualization of vocal fold dynamics. However, due to the insertion of the rigid endoscope in the oral cavity the voice production process including the dynamics of vocal fold vibrations becomes impaired. Therefore, the currently available computerized analysis procedures, which have been designed to enable a highly precise determination of vocal fold vibrations, measure vocal fold dynamics within an non-physiological condition. In this study the influence of rigid laryngoscopy on vocal fold dynamics and on the objectively derived voice measures are quantitatively investigated.
