Laryngitis and Voice Strain
Laryngitis refers to inflammation of the larynx or "voice box." This occurs commonly as the result of a viral infection in the larynx. Laryngitis can also occur secondary to a sinus infection (sinusitis), when there is a constant flow of secretions down the back of the throat (posterior nasal drip), irritating and inflaming the larynx. Voice strain can cause a type of mechanical laryngitis in which the inflammation stems from the voice having been overused. Common symptoms of laryngitis include a hoarse or raspy voice. This may be associated with a sore throat, fever, posterior nasal drip, or congestion of the sinuses. It should not be accompanied by difficulty swallowing food or fluids. This symptom could indicate epiglottitis or peritonsillar abscess. Evaluation will include history and physical examination. Direct visual inspection of the throat will be done to check for signs of bacterial infection. In questionable cases, x-rays of the neck may be useful to diagnose more serious bacterial upper airway infections. A throat culture may be needed to exclude the possibility of "strep throat." Treatment is conservative in most cases. Viral laryngitis is self-limiting and disappears by itself in approximately 7-10 days. Patients with laryngitis (or voice strain) should avoid smoking, rest the voice, avoid alcohol and hot liquids, and drink plenty of fluids. Acetaminophen can be used for pain or fever. A cool mist vaporizer can be therapeutic. Any suspicion of bacterial infection in the throat or sinuses will require antibiotic treatment. Any hoarseness of greater than 3 weeks duration should be evaluated by a your physician or ENT specialist.
