Abstract

Experiments using the excised canine larynges and clinical observations were conducted to clarify the dynamic movement of the air tract fluid on the glottis to lubricate the larynx during phonation.
It was thought that the dynamic movement of the air tract fluid for lubricating of the larynx during phonation was correlated with the vocal fold vibration, especially with the wave motion of the mucous membrane of the vocal fold and dynamic movement of the air tract fluid on the glottis might be one of parameters to evaluate the flexibility of the mucous membrane of the vocal fold.
