Abstract

Based on videostrobokymographic (VSK) examination of over 1200 dysphonic patients we made qualitative assessments of vocal fold (VF) behavior from multiline kymographs and calculated open (OQ) and closed quotients (CQ) for a variety of benign VF pathologies. Statistical analysis showed correlation between OQ and localization of the phonatory lesion within the glottis. For most patients significantly higher OQ were calculated for anterior, middle, and posterior parts of the glottis when compared to the control group.
