Laryngeal examination is the process of visualizing the interior of the larynx, or voicebox. This is part three of the integrative diagnostic model. Screening examination can be completed with the time-honored laryngeal mirror examination. The flexible fiberoptic scope or laryngeal telescope can also be used. Examination is further enhanced through use of strobe illumination to provide apparent slow-motion views of vocal fold vibration, and also by videodocumentation of the examination to allow review and collaboration with other clinicians.
