 +Thanks to videostrobokymography the vocal fold vibration from particular area of glottal chink, can be assessed in an objective way. The aim of this study was the evaluation of vocal fold vibration with the usage of videostrobokymography in patients with different voice disorders. Material of the study included over 2200 patients treated in the institute of physiology and pathology of hearing, audiology and phoniatrics clinic. 100 patients with normal voices, 430 with vocal fold nodules, 276 with polyps, 395 with reinke's edema, 357 with vocal fold paralysis, and 95 with other vocal fold lesions. 567 patients with functional dysphonia were also enrolled into the study. Open quotient (oq) and close quotient (cq) from frontal, middle and posterior third of vocal folds were measured. The study revealed differences of oq and cq in patients with normal voices and those with organic or functional dysphonia. Conclusions: videostrobokymography is an useful complement to classical stroboscopy. It is helpful in differential diagnosis of voice disorders.
