Clinical manifestations Patients can often specify the pharyngeal foreign parts between the oropharynx and the suprasternal fossa, more often in the laryngopharynx, the pharynx can feel like a foreign body, ants, burning, tight binding, stuffy, narrow and other sensations, some patients feel that there are leaves, hair, threads, swelling and sputum adhesion in the pharynx, or feel the ball-shaped foreign body in the pharynx up and down, neither swallowed, nor spit out and cough up, but do not prevent eating; symptoms are sometimes mild and sometimes heavy, or even sometimes not. The symptoms may be mild or severe, or even sometimes absent. The symptoms are obvious when you are in a bad mood or when you are quiet and alone, but they become lighter or disappear when you are happy. There is usually no pain or only a mild sore throat. Etiology: 1. Systemic factors 1. Diseases away from the organs such as gastritis and duodenitis or ulcer, gastric cancer, pyloric spasm, cholelithiasis, left heart enlargement, hypertensive heart disease, pericarditis with effusion, aortic aneurysm, refractive error, etc. 2. 2, systemic diseases are metabolic and endocrine diseases, such as vitamin deficiency, iron deficiency anemia, thyroid diseases such as hyper- or hypothyroidism, menopausal syndrome, myasthenia gravis, cervical osteoarthritis, joint stiffness and intestinal parasites. Iron deficiency anemia is closely related to pharyngeal heterosensitivity, with many patients having low serum iron levels and high unsaturated iron binding. Vitamin deficiencies are supplemented with riboflavin and niacinamide are effective for recalcitrant patients. Second, local factors 1, pharyngeal diseases such as pharyngitis, chronic tonsillitis, tonsil stones, polyps, keratosis, cysts, scarring and abscesses, lingual tonsillitis, hypertelorism, nasopharynx, oropharynx and laryngopharynx foreign bodies, scarring, tumors, tongue root varices, cysts, tumors, stem syndrome, pharyngeal diverticula, etc.. These pains can often be detected by pharyngeal examination, but for early tongue root tumors and tonsillar malignant tumors, it is often not easy to detect them by visual examination only, but by palpation, a local hardening sensation can be felt. For microscopic mucosal erosions hidden between the folds of the pharyngeal mucosa, the opening of the pharyngeal sac at the top of the nasopharynx, adhesions in the pharyngeal crypt, and nasopharyngeal carcinoma developing under the mucosa, they are often missed if the examination is not detailed. Occupation-related pharyngitis, such as dusty, chemical pharyngitis, is also the cause of pharyngeal heterosensitivity. 2. Diseases of adjacent organs Nasal and nasopharyngeal diseases such as sinusitis and nasopharyngitis. Diseases of the larynx such as supraglottic neuritis, rheumatic cricoarytenoid arthritis, epiglottis cyst, abnormal epiglottis morphology, laryngeal chondromyelitis, angioneurotic laryngeal edema, cricopharyngeal muscle and hypopharyngeal constriction spasm, etc. Esophageal diseases such as esophageal spasm, diverticulum, achalasia, early malignancy, traumatic esophagitis, reflux esophagitis, cardia spasm, diaphragmatic hiatal hernia, etc. Neck diseases such as neck masses, fistulas, lymphadenitis, nail and tongue cysts, thyroid inflammation, tumors and others such as dental disease, ear disease, cervical syndrome, glossopharyngeal neuralgia, and carotid arteritis can cause this disease. Among them, it is believed that diaphragmatic hernia is the most important adjacent lesion of pharyngeal obstruction, and reflux esophagitis can lead to pharyngeal obstruction. Due to acidic fluid stimulation of the esophagus, it can disrupt its motor function, and the symptoms improve or disappear after acid control treatment. Early upper esophageal cancer has foreign body sensation or obstruction in the throat, and the symptoms are more obvious when eating, while pharyngeal heterosensitivity is the opposite. Mental factors Mental and emotional changes have an obvious impact on the occurrence and development of dysphagia, such as neurasthenia, neurosis, schizophrenia, fear of cancer, hysteria and anxiety, inhibition, etc.. Traditional Chinese medicine attaches great importance to the disease caused by emotions, and believes that “plum kernel qi” is caused by the seven emotions of depression, phlegm and qi blocking the throat or accompanied by liver and stomach disharmony. “As the plum nucleus obstruction, pharyngeal this can not, spit out the not, in case of mood depression is more, happy mood is seen light”. This fully illustrates the role of mental factors on the disease.
