Chronic pharyngitis is extremely common in clinical practice and often gives people the impression that it is not easy to cure because the symptoms are prone to recurrence and poor treatment. Many patients often go to the hospital, when the doctor prescribed a prescription for treatment is not good, often eat some cephalosporin or erythromycin antibiotics for their own treatment, some of them take the medicine after the symptoms of pharyngeal discomfort is relieved, so they think that oral antibiotics can treat chronic pharyngitis. In fact, there is a certain misconception about this idea. Chronic pharyngitis is a chronic inflammation of the mucosa, submucosa and lymphatic tissue of the pharynx. The symptoms are mainly localized. The symptoms of chronic pharyngitis are similar and varied, such as discomfort, foreign body sensation, itching, burning, dryness or irritation in the pharynx, and may also be slightly painful. Diffuse inflammation is often part of chronic inflammation of the upper respiratory tract, which can sometimes be treated with oral antibiotics, while limited inflammation is mostly inflammation of the pharyngeal lymphatic tissue, which is often not treated with oral antibiotics. We often think that excessive smoking and alcohol, dust, harmful gases and other stimuli and like to eat irritating food can trigger the cause of chronic pharyngitis. There are actually some other causes that we are less familiar with. The lack of knowledge about them leads to incorrect treatment methods, causing chronic pharyngitis to persist for years. Chronic pharyngitis caused by chronic rhinitis and sinusitis. Both nasal and pharyngeal cavities belong to the upper respiratory system, and they also affect each other. Due to inflammation of the nasal cavity and sinuses, which leads to increased nasal and sinus secretions, inflammatory secretions flow backwards through the posterior nostril to the posterior pharyngeal wall, stimulating mucosal hyperplasia and causing pharyngitis to occur. Often people lack the necessary understanding of rhinitis and sinusitis, especially the treatment of sinusitis, resulting in poor treatment of chronic pharyngitis caused by the two aforementioned diseases. Therefore, as long as the diagnosis of rhinitis and sinusitis is clear and treatment is carried out, chronic pharyngitis can be effectively treated. Chronic pharyngitis caused by obstructive sleep apnea hypoventilation syndrome. Obstructive sleep apnea hypoventilation syndrome, commonly known as snoring, refers to apnea and hypoventilation caused by upper airway collapse obstruction during sleep, with snoring, sleep structure disorder, frequent blood oxygen saturation drop, daytime sleepiness and other symptoms. During nighttime sleep, the soft tissues of the upper airway collapse, and some patients have poor nasal ventilation, so in order to maintain effective ventilation, they often use the oropharyngeal cavity to help ventilate, and open-mouth breathing occurs. Many patients often have symptoms such as dry throat or sore throat at night or in the morning, and have the habit of drinking water at night. The mucous membrane in our nasal cavity has structures such as ciliated columnar epithelium and mucous membrane blanket, which can warm and humidify the inhaled and exhaled air, while the oropharyngeal cavity has a weaker role in warming and humidification, so long-term open-mouth ventilation can easily cause excessive dryness of the mucous membrane and lead to chronic inflammation. Many people use some Golden Voice Throat and other tablets for treatment, but the effect is often not ideal. In fact, as long as effective treatment is carried out for snoring, the symptoms of chronic pharyngitis will disappear. Chronic pharyngitis caused by pharyngeal reflux. Pharyngeal reflux is a chronic symptom or mucosal damage caused by abnormal regurgitation of gastric contents into the upper respiratory tract. The clinical symptoms are complex and variable, including intermittent vocal difficulties, chronic throat clearing, excessive laryngeal mucus, cough, postnasal drip sensation, dysphagia, taste disturbance, halitosis and pharyngeal bulb sensation. Some patients also present with long-term chronic pharyngitis symptoms, which manifest as foreign body sensation in the pharynx and pain in the pharynx, with poor results after treatment according to chronic pharyngitis. Therefore, patients with such manifestations should be treated according to pharyngeal reflux in order to treat chronic pharyngitis completely. Therefore, long-term oral antibiotic treatment of chronic pharyngitis not only fails to achieve therapeutic results, but also increases bacterial resistance to antibiotics. The only way to get better results is to identify the causes of chronic pharyngitis and carry out targeted treatment.
