Chronic pharyngitis is a relatively common ENT (ear, nose, and throat) disease. In terms of diagnosis, the first step is to look at the clinical symptoms. Common symptoms include recurrent sore throat, a sensation of a foreign body in the throat, and possibly accompanying swallowing obstruction and breathing difficulties. For auxiliary examinations, a laryngoscopy can be performed. Through laryngoscopy, one can directly observe the specific extent of the lesions inside the throat. For example, there may be chronic congestion of the mucous membrane in the throat and hyperplasia of the lymphatic tissue at the base of the tongue, and then combine these with the experiential judgment of the ENT doctor. Generally speaking, a diagnosis can be confirmed after evaluating these three aspects.
