Pharyngeal tuberculosis
Introduction
Pharyngeal tuberculosis Pharyngeal tuberculosis is a chronic systemic infection caused by tuberculosis, which can be affected by various organs, but tuberculosis is the most common. Pharyngeal tuberculosis is mostly caused by the contact of the pharyngeal mucosa of tuberculosis in tuberculosis patients, or it is caused by the spread of laryngeal tuberculosis, or it can occur in the bloodstream of tuberculosis. Individual pharyngeal tuberculosis is less than throat tuberculosis, and pharyngeal tuberculosis often causes extreme malnutrition due to pain and difficulty swallowing. Mycobacterium tuberculosis is an obligate aerobic bacterium, which has strong resistance to certain physical and chemical factors. Mycobacterium tuberculosis has no endotoxin and does not produce exotoxin and invasive enzymes. Its pathogenic effect mainly depends on the bacterial components, especially the cells. The large amount of lipids contained in the wall, the lipid content is parallel with the virulence of Mycobacterium tuberculosis. The higher the content, the stronger the virulence. The pathogenic effect of Mycobacterium tuberculosis may be the inflammatory reaction caused by the bacteria in the tissue cells, and It is related to the induction of delayed type allergic injury in the body. Mycobacterium tuberculosis can enter the body through the respiratory tract, digestive tract and damaged skin and mucous membranes, invade various tissues and organs, cause corresponding organs, and cause tuberculosis of the corresponding organs. Most of the pharyngeal tuberculosis is caused by the contact with the pharyngeal mucosa of the tuberculosis in the tuberculosis patient, or it is caused by the upward spread of the laryngeal tuberculosis. It can also occur in the bloodstream spread of Mycobacterium tuberculosis. basic knowledge Proportion of disease: among TB patients, the incidence of this disease is about 3%-5% Susceptible people: no special people Mode of infection: spread of germs Complications: difficulty swallowing malnutrition
Cause
Pharyngeal tuberculosis
Mycobacterium tuberculosis is an obligate aerobic bacterium, which has strong resistance to certain physical and chemical factors. Mycobacterium tuberculosis has no endotoxin and does not produce exotoxin and invasive enzymes. Its pathogenic effect mainly depends on the bacterial components, especially the cells.

Most of the pharyngeal tuberculosis is caused by the contact with the pharyngeal mucosa of the tuberculosis in the tuberculosis patient, or it is caused by the upward spread of the laryngeal tuberculosis. It can also occur in the bloodstream spread of Mycobacterium tuberculosis.
Prevention
Pharyngeal tuberculosis prevention
Pay attention to oral hygiene, maintain local cleansing and timely medication, as long as the appropriate treatment, the prognosis is good.
Complication
Pharyngeal tuberculosis complications Complications, difficulty swallowing, malnutrition
1. Patients may have complications such as nasal congestion, runny nose, and hearing loss.
2. Pharyngeal tuberculosis is often caused by pain, difficulty swallowing, causing extreme malnutrition.
Symptom
Pharyngeal tuberculosis symptoms common symptoms ankle perforation swallowing pain nasal congestion hearing loss chronic ulcer
Nasopharyngeal tuberculosis often shows mucosal ulcers or granulation, patients with nasal congestion, runny nose, hearing loss and other symptoms, tonsil tuberculosis, often no obvious symptoms, known as recessive tuberculosis, with tuberculous lymphadenitis, pharyngeal tuberculosis It is classified into two types: acute miliary type and chronic ulcer type.
1. Acute miliary pharyngeal tuberculosis is often secondary to active open tuberculosis or miliary tuberculosis, which is a manifestation of systemic immunity and a malignant complication of severe tuberculosis. The patient has a high temperature and poor general condition, sore throat. Severe, especially swallowing, often radiated to the ear, at the beginning of the disease, most miliary small nodules appear under the mucosa, rapidly ulcerating to form an irregular edge of the ulcer, covered with gray-yellow pollution secretions, occurs in soft palate, The posterior pharyngeal wall and the pharyngeal wall can also occur in the tonsils and other areas and often spread to the mouth and throat.
2. Chronic ulcer-type pharyngeal tuberculosis develops slowly. Except for swallowing pain, other symptoms are not obvious. It occurs in the pharyngeal arch and the posterior pharyngeal wall. There are localized infiltrative lesions on the mucous membrane of pale edema, which then collapses to form shallow Table ulcers, ulcers can be limited to one or several places, the edges are not neat, the mouse bite shape, covered with gray-yellow pseudomembrane, if there is secondary infection, the ulcer occurs and is deeply trapped, forming a sneak edge.
Examine
Examination of pharyngeal tuberculosis
1, biopsy can confirm the diagnosis.
2, according to medical history, clinical manifestations and related laboratory tests, you can find the primary lesion.
Diagnosis
Diagnostic identification of pharyngeal tube
diagnosis
Biopsy can confirm the diagnosis, according to the medical history, clinical manifestations and related laboratory tests, you can find the primary lesion.
Differential diagnosis
The disease needs to be differentiated from pharyngeal lupus and third-stage syphilis.
