Hypertrophic pharyngitis is initially diagnosed by history, symptoms, and signs, and a definitive diagnosis is made by pathologic examination. 1. Medical history: patients with hypertrophic pharyngitis often have a history of recurrent acute pharyngitis, suffer from rhinitis or sinusitis and other nasal diseases, because the nose is not passable and therefore need to open the mouth to breathe, and may have a history of exposure to tobacco and alcohol, dust or irritating gas pollution. 2. Symptoms: patients often feel discomfort in the pharynx, sore, dry or itchy throat, foreign body sensation, burning sensation or smoky sensation, coughing out secretions in the morning, the course of the disease lasts more than 2 months, often caused by cold, fatigue. 3. Physical signs: the posterior wall of the pharynx has more granular elevated lymphoid follicles, which can be scattered or fused into a large block, chronically congested, and the color is like fresh beef. The lateral pharyngeal cords can also be thickened and thickened, showing longitudinal cord-like elevations on the pharyngeal side (behind the palatopharyngeal arch). 4. Pathological examination: mucosal thickening, lymphoid tissue and fibrous connective tissue proliferation, often in the posterior wall of the pharynx to form a granular bulge. If there is pharyngeal discomfort, it is necessary to actively seek medical treatment and improve relevant examinations to clarify the differential diagnosis.
