Acid reflux is the most common cause of chronic laryngitis. But chronic laryngitis may be caused by more severe problems such as nerve damage, sores, polyps, cancer, or hard and thick lumps (nodules) on your vocal cords. The vocal cords are the vibrating elastic bands inside the larynx that produce your voice.
Laryngitis is an inflammation of the larynx. It causes hoarse voice or temporary loss of the voice due to irritation of the vocal folds (vocal cords). Laryngitis is one possible cause of dysphonia, the medical term for a vocal disorder. Laryngitis is categorised as acute if it lasts less than three weeks and chronic if it lasts over three weeks. The chronic form occurs mostly in middle age and is much more common in men than women.
