This review was conducted according to the Patient/problem Intervention Comparison Outcome (PICO) Statements. Some studies reported that 10-30% of patients consulting in ENT come with presenting symptoms of laryngopharyngeal reflux (LPR), but the exact prevalence of LPR is still unknown. Management has not changed in 20 years despite a significant increase in the number of publications on epidemiology, clinical presentation, diagnosis and treatment. The development of hypopharyngeal-esophageal multichannel intraluminal impedance pH monitoring (HEMII-pH) and saliva pepsin detection now allow a new multidimensional diagnostic approach associating clinical scores to HEMII-pH and saliva pepsin detection. This new approach may enable personalized treatment according to LPR profile on HEMII-pH (acid, non-acid, mixed; upright, recumbent reflux episodes). Updated treatment of LPR could consist in a 3-month association of dietary measures, proton pump inhibitors, alginate and magaldrate, followed by treatment adaptation.
