Chronic pharyngitis is a chronic inflammation of the pharyngeal mucosa, submucosa, and lymphatic tissue. Chronic pharyngitis is a chronic inflammatory disease with a slow progression, often coexisting with diseases of adjacent organs or the whole body. It occurs mostly in adults and accounts for about 30% to 50% of pharyngeal diseases in urban residents. Because of its long course, the symptoms are stubborn, short-term difficult to see significant results, so it is not easy to cure. A. Causes 1, acute pharyngitis repeated episodes of failure to completely cure and become chronic, long-term dust or harmful gas stimulation, excessive smoking and alcohol or other bad habits, sinusitis secretions stimulation, allergies or body resistance is reduced. 2, chronic pharyngitis can also be a local manifestation of certain systemic diseases, such as anemia, indigestion, long-term constipation, heart disease, bronchitis, asthma, liver lesions, diabetes and chronic nephritis. 3. Occupational factors. It mainly occurs in voice workers, such as teachers, actors and so on. Because of long-term multi-lingual and singing, can stimulate the pharynx, causing chronic congestion and disease. 1, chronic simple pharyngitis: diffuse congestion of the mucosa, small blood vessels dilated, dark red, with a small amount of mucous secretions. 2, chronic hypertrophic pharyngitis: mucosal thickening, diffuse congestion, dark red. The posterior pharyngeal wall lymphatic follicles are hyperplastic and swollen, dotted or fused into a mass. The lateral cords of both sides of the pharynx are also congested and hypertrophic. 3, atrophic or dry pharyngitis: dry mucosa, atrophy and thinning, pale and shiny like wax paper, and there is pus crust attached. The pharyngeal sensation and reflexes are reduced, and there are also mucous secretions or pus crusts attached to the nasopharynx, and sometimes the outline of the cervical vertebrae can be seen in the posterior pharyngeal wall. If the early atrophy changes are not obvious, only the performance of dry, called dry pharyngitis. Western medical diagnostic criteria 1, medical history: often have a history of recurrent episodes of acute pharyngitis, or long-term open-mouth breathing due to nasal disease and excessive smoking and alcohol, dry bad air, dust and irritating gas pollution. 2, symptoms: pharyngeal discomfort, or pain, or itching, or dryness, burning, smoky, foreign body sensation; irritating cough, coughing up secretions in the morning, or even vomiting. The duration of the disease is more than 2 months, often due to cold, flu, fatigue, talkative and other causes of symptoms 3, examination: chronic congestion in the pharynx, aggravated. Dark red, or dendritic congestion; posterior pharyngeal wall lymphatic follicle hyperplasia, or pharyngeal lateral cord enlargement; pharyngeal mucosa hyperplasia hypertrophy, or dryness, atrophy, thinning, with secretions attached. The diagnosis can be made with the above symptoms and one or more of the above examination findings. Western medical treatment 1, general treatment: do more ideological work, lift the mental burden. 2, remove the cause: such as quit smoking, alcohol and spicy food, treatment of systemic related diseases. 3, local treatment: cryotherapy, electrocoagulation, laser, iodoglycerin and other drugs to rub the posterior pharyngeal wall. 4, systemic treatment: mainly oral drug therapy. At present, there are no effective drugs in Western medicine.
