Your doctor has recommended a procedure to better evaluate your voice. This procedure, called videostroboscopy, allows a close and detailed examination of your pharynx (throat), larynx (voice box) and vocal folds (â€œcordsâ€) at rest and in action.
During the procedure, a small flexible fiberoptic endoscope is passed through your nose to the back of your throat. This allows visualization of your larynx and pharynx. Video examination is performed while you breathe, talk and swallow.
A special light, a strobe, is used to examine the vocal folds in slow motion while you are asked to make certain sounds. Sometimes, a rigid telescope is passed through the mouth to better view the larynx.
The procedure is typically performed by a speech pathologist specially trained in this technique. A small amount of topical anesthesia (usually Lidocaine) and a decongestant (similar to Afrin) will be sprayed into the nose prior to the procedure. No other medications will be given.
You may feel a little throat irritation or dryness during and following the procedure. You may drive yourself home from the procedure immediately afterwards. You may eat a light meal prior to the procedure.
The video of the procedure will be reviewed with you. A physician will review the entire study. Your physician may recommend voice therapy, medical or surgical treatment based on the findings.
