Laryngitis
Laryngitis is inflammation of the larynx (voice box). Symptoms often include a hoarse voice and may include fever, cough, pain in the front of the neck, and trouble swallowing. Typically, these last under 2 weeks.
Laryngitis is categorized as acute if it lasts less than 3 weeks and chronic if symptoms last more than 3 weeks. Acute cases usually occur as part of a viral upper respiratory tract infection, other infections, and trauma such as from coughing or other causes. Chronic cases may occur due to smoking, tuberculosis, allergies, acid reflux, rheumatoid arthritis, or sarcoidosis. The underlying mechanism involves irritation of the vocal cords.
Concerning signs that may require further investigation include stridor, history of radiation therapy to the neck, trouble swallowing, duration of more than 3 weeks, and a history of smoking. If concerning signs are present. the vocal cords should be examined via laryngoscopy. Other conditions that can produce similar symptoms include epiglottitis, croup, inhaling a foreign body, and laryngeal cancer.
The acute form of the infection, or acute laryngitis, generally resolves without specific treatment. Resting the voice and sufficient fluids may help. Antibiotics generally do not appear to be useful in the acute form. The acute form is common while the chronic form of the infection, or chronic laryngitis, is not. Chronic laryngitis occurs most often in middle age and is more common in men than women.
The primary symptom of laryngitis is a hoarse voice. Because laryngitis can have various causes, other signs and symptoms may vary. They can include:
Aside from a hoarse-sounding voice, changes to pitch and volume may occur with laryngitis. Speakers may experience a lower or higher pitch than normal, depending on whether their vocal folds are swollen or stiff. They may also have breathier voices, as more air flows through the space between the vocal folds (the glottis), quieter volume, and a reduced range.
Laryngitis can be infectious as well as noninfectious in origin. The resulting inflammation of the vocal folds results in a distortion of the sound produced there. It normally develops in response to either an infection, trauma to the vocal folds, or allergies. Chronic laryngitis may also be caused by more severe problems, such as nerve damage, sores, and polyps, or hard and thick lumps (nodules) on the vocal cords.
