Laryngitis is when the voice box or vocal cords become inflamed from overuse, irritation, or infection. There are two main types of laryngitis: chronic (long-term) and acute (short-term). The inflammation that causes laryngitis can be tied to a variety of conditions.  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.  There are two types of laryngitis: acute laryngitis and chronic laryngitis.

Laryngitis is the medical term for inflammation and swelling of the larynx, which is also known as the voice box. Most of the causes of laryngitis, such as common viruses infections or using your voice too much, are not serious. A few causes, however, require medical attention and can be cause for concern such as laryngeal cancer. As such, when laryngitis persists, be aware that this may indicate a more significant medical problem. Reflux Laryngitis. Reflux is caused by weakness in the muscle at the junction of the esophagus with the stomach. Normally, this muscular valve, or sphincter, functions to keep food and stomach acid from moving upward from the stomach to the esophagus and larynx.  Laryngitis is an inflammation of the voice box, or larynx (say LAIR-inks), that causes your voice to become raspy or hoarse. Laryngitis can be short-term or long-lasting (chronic). Most of the time, it comes on quickly and lasts no more than 2 weeks. Chronic symptoms are those that last 2 weeks or longer.
