What is Vocal Cord Stroboscopy?

Stroboscopy of the vocal cords is a special exam whereby a scope is introduced down into the throat where the vocal cords can be directly visualized. Using a special light, the vibration of the vocal cords can be examined and allows identification of subtle pathology that can contribute to a raspy voice.

The exam is recorded and can be played back at any speed to allow for careful analysis.

Here is a YouTube video our office has made showing how this exam is performed!
