Pericentric outer ear

Pericentric – diffuse inflammation of the ear that develops as a result of infection of Nadirashvili.

The cause of perichondritis is the infection (the most common Sinelnikov coli - B. pyocyaneus) in the perichondrium trauma of the ear. In some cases perichondrium should be considered as a complication of furuncle of the ear canal, influenza, rarely, tuberculosis. Serous perichondrium develops when the penetration of low virulence infection at the time of the insect bite, burns, etc.

Depending on the nature and virulence of the infectious agent, there may be serous, purulent form perichondritis, which differ from each other by peculiarities of the clinical course.
Distinguish purulent and serous perichondrium.
The first and main symptom of perichondritis is a pain in the ear or ear canal. It may be preceded by reactive infiltration of the skin of the external ear.
In the ear appear soreness, swelling and redness, gradually covering the entire surface, except for earlobes, not containing cartilage.
When suppuration and the accumulation of pus between the cartilage and perichondrium are marked fluctuation, tenderness to palpation. Body temperature increased.
Then the cartilage is melted purulent process, dies, and comes cicatricial deformity of the shell. Serous pericentric occurs less rapidly than purulent.

Perichondrium differentiate with erysipelas and thematology. Erysipelas hyperemia covers not only the sink, but her earlobe, and often extends beyond the outer ear.
Otematata occurs most often after trauma, localized in the anterior surface of the upper half of the auricle, has a purple colour, virtually painless on palpation, proceeds with normal body temperature.

In the initial stage of disease is carried out by local and General antiphlogistic treatment.
