Spatiotemporal distribution of the intraglottal pressure and vocal fold contact pressure in excised larynges.

ABSTRACT: The contact pressure experienced by the vocal folds during phonation is considered a major factor contributing to vocal fold injuries and lesions. Understanding the spatiotemporal distribution of vocal fold contact pressure across the medial surface and its dependence on laryngeal geometrical and mechanical properties (such as glottal gap, vocal fold vertical thickness, vocal fold length, and vocal fold stiffness) is essential to identifying strategies that minimize contact pressure and reduce the risk of vocal injury. This study aims to characterize the spatiotemporal distribution of intraglottal pressure across the medial surface in excised larynges. The intraglottal pressure was measured using a modified probe microphone at different locations within the vertical plane containing the gl
