DISEASES OF THE EAR : TUBERCULOSIS OF EAR TUBERCULOSIS AURIS) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
The tubercle Bacillus. Pathologically small-cell infiltration of the mucosa of the middle ear - the formation of scattered tubercles with giant cells, vasodilatation.
Symptoms and recognition. In tuberculosis of the external ear most often affects the lobe. Piercing earlobes to wear earrings favorable for the occurrence of the primary lesion. The process may remain local for a long time; regional lymph nodes are usually involved in the process. Tuberculous pericentric begins in the form of a furuncle of the external auditory canal; then infiltrate spreads to the ear and, finally, a fistula is formed at the junction of the cartilage of the external auditory canal in the cartilage shell. In lupus on the ear appear nodules, covered with brownish-red skin not change its color from the pressure. All ears are more or less deformed. Tuberculosis of the middle ear is always a secondary process. Pain rare. Characteristic painless process and rapidly progressing hearing loss, sometimes even before the formation of the perforation, suppuration with a pungent odor, slight temperature, a plurality of prabodhini (in place of the decaying tubercular nodules). When developing tuberculous mastoiditis frequent fistulas and sequestration, frequent paralysis of the facial nerve. The diagnosis must be supported by grafting an experienced animal. Not to be confused tuberculosis of the middle ear with otitis media in tuberculosis; otitis these can be very peculiar, depending on the immunological status of the patient. Tuberculosis of the inner ear is localized first in the membranous labyrinth, and then moves on to a bone; starts without acute symptoms; dizziness, nausea, vomiting are mild, ear falls rapidly. The presence of sequesters recognizable x-rays.
For a long period.
A cautious prediction depends on the immunological status of the patient.
General strengthening of the body with the use of physiotherapeutic procedures (exposure patient's ear with ultraviolet rays, climatotherapy, stay outdoors), medical treatment is the same as in ordinary chronic otitis (see).
