Reflux laryngitis: pathophysiology, diagnosis, and management.

Gastroesophageal reflux disease is felt to be associated with a variety of laryngeal conditions and symptoms of which "reflux laryngitis" is perhaps the most common. The most likely mechanism for laryngeal injury and symptoms is secondary to direct acid and pepsin contact, although studies concerning the cause and effect between gastroesophageal reflux disease and laryngeal disorders are conflicting. Likewise, the most effective method to diagnose such patients is unclear. Empiric treatment of patients with reflux laryngitis has been shown to be effective though none of the studies are controlled.
