The nose and pharynx are two important gateways to the respiratory tract that interact with each other. In layman’s terms, rhinitis: inflammation of this anatomical structure behind the nasal vestibule to above the soft palate; pharyngitis: pharyngeal bulla to above the laryngeal chambers. Rhinitis, or inflammatory disease of the nasal cavity, is an inflammation of the nasal mucosa caused by viruses, bacteria, allergens, various physicochemical factors, and certain systemic diseases. The main pathological changes of rhinitis are congestion, swelling, exudation, hyperplasia, atrophy or necrosis of the nasal mucosa. (Subsequent will be classified rhinitis) Pharyngitis is an inflammation of the mucous membrane of the pharynx, submucosal tissue, often as part of an upper respiratory tract infection. (Subsequent classification pharyngitis) Many pharyngitis patients often have this question, they have had pharyngitis for several years, also took the appropriate treatment measures, but the effect is not very good, clinical symptoms often appear as follows: pain in the throat, phlegm, as if there is an endless spit of phlegm, sometimes phlegm will also have blood, will cough, there will be ear congestion tinnitus, every time after the cold will attack, and the symptoms are heavier than the original. So, why does pharyngitis persist and recur? The vast majority of them are related to rhinitis, and it should be said that most rhinitis patients have a bad pharynx. The common causes of persistent pharyngitis: 1, long-term nasal reflux stimulates the throat, causing laryngitis, such as foreign body sensation, pharyngeal itching, burning, dryness, micro-pain, etc.; 2, long-term nasal congestion, open mouth breathing caused by dry and cold air directly to the throat and dry pain; 3, chronic rhinitis people with low immune function, it will recur, resulting in nasopharyngeal mucosal tissue hyperplasia, hypertrophy narrow stimulation of the throat caused by a variety of discomfort; 4, sticky phlegm often attached to the pharynx. The most common cause of pharyngitis is a chronic cough, which is common in children (due to rhinitis leading to pharyngitis and bronchitis); 6. The most important thing is that pharyngitis is an important radar station for the body, and it is time to actively look for the cause. (The logical relationship between allergic rhinitis, allergic pharyngitis and allergic bronchitis (so-called “asthma”) in this process is that rhinitis is treated for rhinitis, pharyngitis for rhinitis and pharyngitis, and asthma for rhinitis, pharyngitis and asthma. asthma. Because the nose is the wall of the respiratory tract, the first to come into contact with allergens.
