Laryngovideostroboscopy is a valuable tool in the diagnosis of voice disorders. Using a strobe light, it allows the doctor to carefully examine the vocal folds in slow motion. These images are retrieved by either placing a tube in the back of the mouth, or inserting a fine and flexible tube through the nose and into the throat after the application of local anaesthetic. Video pictures are then taken while the patient talks, sings or whistles.
