Videostroboscopy is a new, state-of-the-art procedure for recording and observing the motion of the vocal cords. The procedure utilizes an endoscope to make a video recording of your larynx and vocal cords, which can then be analyzed on a computer. Although the vocal cords can be seen with the naked eye, only videostroboscopy can allow your doctor to see the actual vibrations of your vocal cords. By digitally slowing down the vibrations, videostroboscopy can reveal problems such as polyps or vibratory irregularities. During the exam, you will be asked to pronounce certain sounds which will be visually recorded. After the exam, the digital images can be played back on a computer for careful analysis. Videostroboscopy is usually performed by a trained speech pathologist or a physician. The examination is relatively simple to perform, and only a topical anesthetic is needed.
