Videostroboscopy is a specialized imaging test that closely examines how your vocal folds (vocal cords) move during speech. If you're experiencing hoarseness, vocal fatigue, loss of range (especially in singers), or a voice that just "doesn't sound right," this is a key diagnostic tool. It uses a camera and strobe light to create a slow-motion view of your vocal fold vibrations, helping your doctor identify even subtle problems like nodules, polyps, stiffness, or scarring.

The procedure takes about 10–15 minutes in the office. A small scope is passed through your mouth or nose while you make various vocal sounds. It is not painful, though the nose may be numbed with spray to improve comfort. You'll be asked to say "eeee,” glide your pitch, or speak briefly while the vocal folds are recorded. You can return to speaking and normal activity immediately after. There is no downtime or recovery. The results help guide voice therapy, surgical decisions, or ongoing care. Videostroboscopy is highly effective and safe, and in many cases, only one session is needed for diagnosis — though it may be repeated over time to monitor progress.
