Laryngeal videostroboscopy

Laryngeal videostroboscopy is a technique of examining the larynx that includes special endoscopes coupled to both continuous and strobe light, a video system, a TV monitor, and a computer. This technique produces highly magnified views of the larynx that are video documented for later study or review with patient, speech pathologist, family, and so forth. In normal light the vibration of the folds would appear as a blur; the strobe light reveals apparent individual cycles of vibration for assessment.
