Laryngopharyngeal reflux (LPR) is a common and often misinterpreted clinical entity responsible for various symptoms affecting the upper aerodigestive tract. This narrative literature review aims to review the pathophysiology, symptoms, and management of LPR, emphasizing the emerging understanding of gastric content reflux in aerodigestive tissue irritation. Understanding the pathophysiology of LPR will allow general practitioners and specialists to accurately recognize and treat a condition that causes substantial morbidity in the affected patients. Using evidence-based findings from randomized controlled trials, clinical studies, and meta-analyses, the present investigation aims to outline and unify previous research into LPR. A review of anatomical structures, pathogenic mechanisms, endoscopic findings in LPR, and clinical manifestations and treatment options are also discussed. Though controversy around the diagnosis and management of LPR persists, emerging research in cellular damage and diagnostic tools promises to provide increasingly accurate and reliable modalities for characterizing LPR. Hopefully, future research will unify the field and provide overarching guidelines for both primary care and specialists. The present investigation provides an integrated perspective on LPR, a clinically prevalent and complex disease.
