VIDEOKYMOGRAPHIC ANALYSIS OF VOCAL FOLD VIBRATION IN UNILATERAL VOCAL FOLD PARALYSIS

Popis výsledku v původním jazyce

The study investigated vocal fold vibration in patients with unilateral vocal fold paralysis with the aim of answering the following questions: I) Does the paralyzed vocal fold tend to vibrate faster or slower than the healthy vocal fold? II) What are the most important features that distinguish the vibration of the paralyzed from the healthy vocal fold? A systematic protocol, which visually rates 33 vibratory features of the vocal folds using pictograms, was used to evaluate videokymographic images obtained from 46 patients diagnosed with unilateral vocal fold paralysis. The evaluation was done independently by four evaluators. Statistical analysis of the parameters was performed using the R GNU and G-power software. The results revealed a statistically significant tendency of the paralyzed vocal fold to vibrate with different frequency, amplitude and phase than the healthy vocal fold. However, there was no clear tendency of the paralyzed vocal fold to vibrate slower or faster than th
