In flexible laryngoscopy, a think flexible fiberoptic view tube (called a laryngoscope) is passed through the nose and guided to the vocal cords (larynx). This is a procedure that is routinely performed in the office by an ear, nose and throat physician to examine areas of a patient that can otherwise not be seen. The inside of the nose is anesthetized with a topical spray prior to viewing. This allows a comfortable experience. It is used to help determined the cause of difficulty swallowing, breathing, coughing or hoarseness. It is particularly helpful in evaluating voice problems. The technique allows the physician to video the vocal cords, show their movement on the video screen and thereby better assess the source of the voice disorder.
