Summary Background Despite increasing clinical and experimental evidence of its existence, otolaryngological manifestations of reflux disease remain controversial, concerning diagnosis as well as treatment. Aim Proper understanding of laryngopharyngeal reflux disease (LPRD). Method Review of literature. Results Scepticism concerning LPRD is based upon differences between gastro‐oesophageal reflux disease and LPRD; lack of specificity and sensitivity of diagnostic tests to confirm LPRD; non‐specificity of laryngological symptoms, which are difficult to distinguish from other causes of upper respiratory tract inflammation; non‐specificity of laryngological signs in laryngoscopy, with high intra‐ and inter‐observer variability in evaluation; diagnosis of LPRD is essentially only based on a combination of diagnostic signs and symptoms, which cannot be attributed to other pathology; slow, or sometimes lack of, response of LPRD symptoms to proton pump inhibitor (PPI) medication and lack of evidence concerning efficacy of PPIs in placebo‐controlled trials. Conclusions LPRD remains a diagnosis by exclusion and resolution of symptoms following 4‐month trial of 40 mg PPI twice daily is, for all practical purposes, considered proof of the initial diagnosis. However, non‐response does not exclude LPRD as PPIs have no influence on noxious non‐acid components of the refluxate.
