Why is this test being done?
This procedure is done to visualize the upper airway and most commonly used to rule out vocal cord dysfunction. It involves the use of a small flexible fiberoptic scope inserted through the patient's anesthetized nasal passage.
Preparing for the test
Before the test, a nasal spray that consists of a decongestant and an anesthetic will be administered to prepare your nose for the test.
During the test
During the rhinolaryngoscopy a small fiberoptic camera/scope is placed in your nose. The scope is passed through your nose to the back of your throat. The movement of the vocal cords can be seen with the scope. You will likely be asked to make certain sounds and to breathe in a certain way while the camera is in place. After thorough evaluation the camera is removed. The procedure takes no more than 2 minutes. A recording of this procedure can be made. Please do not eat 1-2 hours prior to the test if a laryngoscopy has been scheduled.
