The work assessed clinical utility of open quotients measured during laryngovideostroboscopy and electroglottography. Values of the parameters were analyzed according to clinical diagnosis. An algorithm based on direct and indirect mucosal wave measurement is presented, which allows for differentiation of voice disorders. The method developed for the objectification of glottal functions in various voice pathologies is characterized by high sensitivity and specificity.
