Laryngopharyngeal reflux disease in adult patients: tears and pepsin
Laryngopharyngeal reflux disease (LPRD) is defined as the retrograde flow of stomach content to the upper aero-digestive structures, with an estimate incidence about 4-10% of the general population.(1). LPRD is used to describe the pathological condition caused by the reflux of gastric and/or duodenal juices to the larynx, oropharynx and/or nasopharynx, through the upper oesophagus sphincter (UES). The most frequent symptoms are dysphonia, chronic cough, sore throat, excess throat mucus and pharyngeus globous. Endoscopy
