What is Acute laryngitis?
Laryngitis is an inflammation of the larynx. It causes hoarse voice or temporary complete loss of the voice because of irritation to the vocal folds (vocal cords). Dysphonia is the medical term for a vocal disorder, of which laryngitis is one cause.
Laryngitis is categorised as acute if it lasts less than three weeks. Otherwise it is categorised as chronic, and may last over three weeks. The chronic form occurs mostly in middle age and is much more common in men than women.
