Speech is a fundamental human trait.  Many professionals depend on their voice for their livelihood.  However, anyone with persistent hoarseness should have the larynx examined to determine the cause of their voice change and to improve the quality of their voice. Videostroboscopy is a specialized test for examining the function and motion of the vocal folds.  

Videostroboscopy combines fiberoptic endoscopy and strobe light technology to permit a functional evaluation of the larynx.  The vocal folds vibrate at high frequencies to produce sound.   The strobe technology creates the illusion of a static or slowed down vocal fold movement, and it allows your physician to understand better the cause of your hoarseness.
