Videostroboscopy

Videostroboscopy is a type of laryngoendoscopic procedure that utilizes a flexible or rigid endoscope that is connected to a stroboscopic light source, which emits a pulsing light that provides an optical illusion of the vocal folds moving in slow motion.

Videostroboscopy has advantages over some other laryngoendoscopic procedures in that it allows the image to be stored on a computer and analyzed further. Videostroboscopy also allows the voice pathologist to analyze the following parameters of vocal fold vibration:

1. Symmetry of vibration
2. Amplitude of vibration
3. Periodicity of vibration
4. Mucosal wave
5. Closure pattern
