Laryngopharyngeal reflux in children- a current Otolaryngologist’s perspective

Abstract

Gastroesophageal reflux disease (GERD) is diagnosed when the reflux of the stomach contents causes complications or troublesome symptoms. This disease can present with esophageal or extraesophageal symptoms. Laryngopharyngeal reflux (LPR) occurs when gastric contents reflux beyond the oesophagus to laryngopharynx, oropharynx or nasopharynx and it can cause symptoms such as: globus, hoarseness, chronic cough, regurgitations, vomiting or failure to thrive in infants. LPR can influence clinical course of many diseases 
i.a laryngomalacia, subglottic stenosis, chronic hoarseness and/or recurrent respiratory papillomatosis. LPR is also believed to be a factor leading to formation of laryngeal granulomas, ulcerations, Reinke’s edema, functional voice disorders, sinusitis, otitis media or even life threatening events in neonates. The main diagnostic methods currently used are laryngoscopy, 24-hours pH-metry and esophageal multichannel intraluminal impedance testing. Treatment consist of lifestyle changes and pharmacologic treatment.The use of antireflux medications is not recommended in patients with extraesophageal symptoms in absence of typical GERD symptoms. Surgical treatment can be considered in children with severe LPR symptoms refractory to pharmacological treatment. Controversies regarding diagnosis and treatment of LPR still exists. Further investigations are needed to establish guidelines for the diagnosis and management of LPR.
