The most accurate way to determine reflux pharyngitis is esophageal bipolar pH monitoring and experimental acid suppression therapy.
Reflux pharyngitis is an inflammatory disease caused by reflux of gastric contents into the pharynx and irritation of the mucous membrane of the pharynx. Typical clinical manifestations include hoarseness and throat discomfort.
Diagnosis of the disease can be aided by 24-hour monitoring of esophageal bipolar pH. In addition to the above diagnostic methods, experimental acid-suppressive therapy has also become a criterion for determining reflux pharyngitis, which can help doctors diagnose reflux pharyngitis when clinical symptoms are significantly improved after the administration of acid-suppressive drugs, such as proton pump inhibitors, e.g., rabeprazole and omeprazole.
Therefore, when you suspect reflux pharyngitis, you can use the above methods combined with clinical manifestations to help diagnose the disease.
