[Nocturnal gastroesophageal reflux as a cause of refractory chronic laryngitis--pathophysiology and management].
Chronic laryngitis is a common disease with a multifactoral genesis. One of the known causal factors is gastrolaryngeal acid reflux as a consequence of gastroesophageal reflux disease (GERD). 10 to 30% of the patients do not show an adequate response to the standard treatment with proton pump inhibitors, which could not be well explained in the past. Our own observations indicate, that sleep related gastroesophageal reflux may play an important role. The special physiological conditions in sleep can impair the reflux, and an increased nocturnal breathing effort in snoring or sleep apnea induces an intensive gastrolaryngeal reflux. This paper explains the pathophysiological background and the diagnostics and differential treatment.
