The ability to see the vocal folds is crucial to a comprehensive evaluation of hoarseness. This is typically done with a flexible laryngoscope that passes through the nose or a rigid scope that shines a light down the throat through the mouth. This exam is routinely done in the office and takes only a few minutes.

Video laryngostroboscopy is a special instrument that uses a strobe light and microphone to synchronize the movements of the vocal folds so that the vibration of the folds may be viewed in slow motion. The evaluation may be recorded for review and saved as part of your medical record.
