Videokymography. Imaging and quantification of regular and irregular vocal fold vibrations

A newly developed imaging technique makes it possible to observe the vocal fold vibration pattern also under unstable conditions. In contrast to stroboscopy, which strongly relies on the regularity of the vibration under study videokymography enables the study of irregular patterns as well. The method is very useful for observing left-right asymmetries, especially in vocal fold and laryngeal pathology.
