Perichondritis of an outside ear

Description:

Perichondritis – the diffuse inflammation of an auricle developing as a result of infection of a nadkhryashchnitsa.

Reasons of a perichondritis of an outside ear:

Hit of an infection (more often than a pyocyanic stick - V. of pyocyaneus) in a nadkhryashchnitsa is the reason of a perichondritis at an auricle injury. In some cases the perichondritis should be considered as a complication of a furuncle of acoustical pass, flu, is more rare than tuberculosis. The serous perichondritis develops at penetration of a slabovirulentny infection at the time of sting, at a burn, etc.

Symptoms of a perichondritis of an outside ear:

Depending on character and virulence of the infectious agent, it can be observed a serous, purulent form of a perichondritis which differ from each other in features of a clinical current.

Distinguish a purulent and serous perichondritis.

The first and main symptom of a perichondritis is auricle pain or acoustical pass. It can precede reactive infiltration of skin of an outside ear.

In an auricle there are a morbidity, puffiness and a hyperemia which are gradually covering all its surface except for the lobe which is not containing a cartilage.

At suppuration and accumulation of pus between a cartilage and a nadkhryashchnitsa fluctuation, morbidity at a palpation are noted. Body temperature is increased.
Then the cartilage melts purulent process, perishes, and there occurs cicatricial deformation of a sink. The serous perichondritis proceeds less violently, than purulent.

Diagnosis:

The perichondritis is differentiated with an erysipelatous inflammation and an othematoma. At an erysipelatous inflammation the hyperemia covers not only a sink, but also its lobe, and also quite often extends out of limits of an outside ear.

The othematoma arises more often after an injury, is localized in the field of a front surface of an upper half of an auricle, has crimson coloring, a maloboleznenn at a palpation, proceeds with normal body temperature.

Treatment of a perichondritis of an outside ear:

In an initial stage of a disease carry out topical and general antiinflammatory treatment.

At identification of a pyocyanic stick penicillin is inefficient. Appoint polymyxin M (1% - ny ointment or an emulsion), inside tetracycline, Oletetrinum or Oxytetracyclinum on 250 000 PIECES of 4-6 times a day, erythromycin on 250 000 PIECES of 4-6 times a day, streptomycin on 250 000 PIECES 2 times a day intramusculary.

The struck part of a sink is greased by 5% - ache tincture of iodine, 10% - a ny lyapis. Carry out physical therapy in the form of Ural federal district, UVCh or the microwave oven. In a number of chronic cases use a roentgenotherapy.

At suppuration make a wide section of fabrics parallel to auricle contours, delete nekrotizirovanny parts of a cartilage, scrape out an abscess cavity a spoon and enter into it a tampon with antibiotics.
