Laryngopharyngeal Reflux

Abstract

The prevalence of laryngopharyngeal reflux (LPR) is around 31 % in the general population. Patients with a dysphonia or other laryngeal diseases are accompanied up to 50 % by an LPR. Typical reflux associated diseases of the larynx are a chronical laryngitis and a contact granuloma. The role of LPR is still not clarified in the development of a glottic carcinoma. There still doesn't exist evidence based data for the diagnosis of a LPR. Therefore LPR is usually clinically diagnosed by a combination of typical symptoms like hoarseness, chronic coughing, relapsing throat clearing, globus pharyngis and dysphagia as well as through the laryngoscopic characteristics like mucosal erythema, mucosal hyperplasia with plication of the interarytenoid region and an edema of the vocal cords. Occasionally the LPR can be ensured with the additional method of the pharyngeal 24-hour pH-monitoring. The therapy of the LPR is a multimodal for example dietary arrangements, medication with proton pump inhibitors and where indicated a surgical intervention. The treatment of a symptomatic patient is administered by proton pump inhibitors in a close dialog with the ENT practitioner and the gastroenterologist.
