Characteristics of Euphony in Direct and Indirect Mucosal Wave Imaging Techniques.
OBJECTIVES
There is a necessity to include objective methods to the study protocol of voice. Such procedure will help not only in diagnosing and monitoring the course of treatment, but also in comparing the results of studies between research centers.


METHODS
Vocal fold mucosal wave characteristics of 70 healthy people were made using videostrobokymographic open quotient (VSKOQ) and electroglottographic quasi-open quotient (EGGQOQ).


RESULTS
Statistically significant differences were achieved regarding gender for the averaged values of VSKOQ as well as for values calculated from the posterior part of the vocal folds. A statistically significant correlation between the value of VSKOQ and age was observed for the posterior part of the glottis. Differences between gender and the value of EGGQOQ were observed. No statistically significant correlation between EGGQOQ and age was obtained.


CONCLUSIONS
VSKOQ and EGGQOQ are parameters characterizing glottal function in a coherent manner. These parameters can be included easily in phoniatric examination and help to objectify glottal function.
