This is an optical instrument that assists the doctor during the examination of the larynx and vocal cords. This device has a flexible fiber optic cable that the doctor passes through the nose and the back of the throat until he sees the vocal folds. Because of the flexibility of the scope, the patient does not gag and is comfortable. With this device, the doctor can examine the larynx during normal speech and evaluate for gastric reflux, hoarseness and chronic cough.
