Ear tuberculosis

Tuberculosis of the outer ear is a secondary manifestation of tuberculosis - it develops on the auricle as a result of the transition of the process from the face. A nodule appears in the region of the lobe, sometimes with ulceration of the skin, in some cases tuberculous perichondritis occurs; with lupus, multiple nodules (lupomas), merging into infiltrate.

Tuberculosis of the middle ear occurs hematogenously and less often in the tubular way. The onset is asymptomatic (without pain and fever), the course is sluggish, chronic. There may be not one, but several increasing perforations of the tympanic membrane as a result of the collapse of the tubercles. Suppuration is insignificant, serous-mucous or creamy purulent, with an unpleasant odor. The parotid lymph nodes are enlarged. As a result of the collapse of the tubercles on the mucous membrane of the middle ear, ulcerations occur with granulations protruding into the external auditory canal. The process can take on a necrotic character with sequestration of the middle ear, ear canal, labyrinth and the formation of fistulas.

Tuberculous mastoiditis is a common complication in children. The course of mastoiditis and labyrinthitis is latent. There may be peripheral paresis of the facial nerve due to destruction of the bone wall of its channel. Intracranial complications are rare.
Sometimes sluggish limited or diffuse labyrinthitis develops. Progressive mixed hearing loss can turn into sensorineural with damage to the auditory nerve up to deafness. After recovery, a pronounced adhesive process remains in the middle ear.

The diagnosis is made on the basis of taking into account the primary lesion in the body, bacteriological examination of pus from the ear (tuberculous mycobacteria are often not detected), as well as histological examination of the nodule on the auricle, granulation and sequestration from the middle and outer ear. Biological method - infection of guinea pigs with pus from the ear confirms the diagnosis.

Treatment. Streptomycin 0.5-1.0 g per day, phthivazide, PASK and other anti-TB drugs. Local treatment of chronic suppurative otitis media using streptomycin in the form of an ointment or emulsion, 0.3% formalin solution. With mastoiditis, mastoidal or sparing radical surgery, depending on the prevalence of bone destruction.

BCG otitis is observed in young children after oral administration of the tuberculosis vaccine. There is a temperature-free chronic otitis media with flaccid granulations in the middle ear and ear canal. The course is favorable.

Ear tuberculosis

  1. Middle Ear Tuberculosis
    Tuberculosis of the middle ear is rare, occurs when the infection spreads through the hematogenous route from some distant primary focus, most often from the lungs. This position, in particular, is confirmed by the occurrence, most often in early childhood, of a lesion of the mastoid process without previous inflammation in the tympanic cavity. An important role in the emergence and development
  2. EAR INJURY, FOREIGN BODY OF THE EAR
    In case of an external ear injury, first aid is similar to first aid for injuries. Damage to the eardrum can occur during explosions, diving, during diving operations. The rupture of the membrane is accompanied by pain, hearing loss, minor bleeding from the ear. First aid: - insert a sterile cotton swab into the external auditory meatus; - put on the ear
  3. Tuberculosis
    Tuberculosis is a chronic granulomatous infectious disease caused by mycobacterium tuberculosis. The transmission route is aerogenic or alimentary. There are primary, hematogenous and secondary tuberculosis. Primary tuberculosis occurs as a result of a primary infection of the human body with a Koch bacillus, as a result of which a primary tuberculosis complex develops. Three possible
  4. Tuberculosis
    The leadership of the Institutions ensures the organization and implementation of a set of anti-tuberculosis measures, including health education on prevention, early detection of tuberculosis and the controlled treatment of patients with tuberculosis. Tuberculosis hospitals are the organizational and methodological centers for tuberculosis work in Institutions.
  5. TUBERCULOSIS
    The incidence of tuberculosis in pregnant women depends on its prevalence in the population and region. In recent years, there has been a noticeable increase in the overall incidence of tuberculosis in the Russian Federation, which causes an increase in the frequency of development of this pathology in pregnant women. The most common form of tuberculosis is pulmonary tuberculosis. The disease is detected in approximately 0.3
  6. LESSON 15 TOPIC. TUBERCULOSIS
    Motivational characteristic of the topic. Knowledge of the topic materials is necessary for the study of tuberculosis in clinical departments. In the practical work of the doctor, this knowledge is necessary for the clinical anatomical analysis of this pathology. The general purpose of the lesson. According to the knowledge of the morphological manifestations of tuberculosis, learn to determine the clinical and anatomical variants of different forms of this severe infectious disease. Specific
  7. TUBERCULOSIS
    TUBERCULOSIS is an infectious disease of humans and animals caused by mycobacterium tuberculosis, characterized by a chronic relapsing course. Tuberculosis is based on specific granulomatous inflammation. In humans, the disease most often causes 2 strains of mycobacterium tuberculosis: human and bovine. Infection with the human type occurs by airborne droplets, bovine -
  8. TUBERCULOSIS
    Tuberculosis (lat., English. - Tuberculosis) is a severe chronic disease of animals of many species and humans, characterized by the formation of specific nodules in various organs - tuberculosis, undergoing caseous necrosis and calcification (see color insert). Historical background, distribution, hazard and damage. Tuberculosis has been known since antiquity. Signs of illness in humans

  10. TUBERCULOSIS
    Tuberculosis? an infectious disease caused by mycobacterium tuberculosis and characterized by the development of cell allergies, specific granulomas in various organs and tissues with a polymorphic clinical picture. Characteristic damage to the lungs, lymphatic system, bones, joints, genitourinary organs, skin, eyes, nervous system. If untreated, the disease progresses and ends

    Tuberculosis is an infectious disease that affects mainly the human lungs, but it is also possible damage to the bones, joints, skin, kidneys, and nervous system. Tuberculosis is a bacterial disease. Its causative agent is the so-called tubercle bacilli or Koch bacteria. They are quite stable in the environment, tolerate prolonged drying (about three months).

  13. Hematogenous tuberculosis
    • Occurs after suffering primary tuberculosis in the presence of foci of hematogenous screenings or not fully healed tricks in the lymph nodes against a background of pronounced immunity to mycobacteria, but with increased sensitivity (sensitization to tuberculin). • Productive tissue reaction (granuloma) predominates. • A tendency to hematogenous generalization is expressed. Varieties
  14. Tuberculosis
    Tuberculosis is an infectious disease that affects mainly the lungs. See the article EASY (PROBLEMS), with the addition that this disease is a very important signal, since with untimely treatment it can lead to serious consequences, including death. If tuberculosis does not affect the lungs, but some other organ, see the relevant article in this
  15. Tuberculosis
    This is an infectious disease caused by several varieties of acid-resistant mycobacteria (genus Mycobacterium) (the old name is Koch's bacillus) and characterized by the occurrence of specific inflammatory changes in various organs. The main source of infection is a patient who produces sputum, which contains microbes. Infection occurs mainly
  16. Tuberculosis
    Tuberculosis (tubeculosis) is a chronic infectious disease of most animal and human species, characterized by the formation of specific granulomas (tuberculosis) in organs and tissues. The disease causes great economic damage, which is the sum of the costs of quarantine measures, delivery of animals reacting to tuberculin and other factors for slaughter. In the Republic of Belarus
