Eczema is a serous inflammation of the skin with a chronic acute relapsing course and polymorphism of the elements of the rash (small seropapules or vesicles against the background of edematous erythema by wetting and crusting; large-pitted foci, erythematous-scaly spots, etc.). Eczema of the external ear is relatively common, especially in children.

Et and about l about d and I. The disease usually develops as a result of irritation of the skin of the auricle and ear canal by secretions from the ear in acute and chronic purulent otitis media (microbial form), iodine preparations, with prolonged exposure to coal and cement dust, etc. (allergic form). Eczema can occur as a manifestation of intolerance to various substances (allergic form) or on the basis of a number of common diseases (diabetes, some forms of metabolic disorders).

In childhood, the onset of eczema exudative diathesis, rickets, often tuberculosis. Eczema of the external ear appears after a traumatic effect when infection penetrates and the local resistance of the body weakens.

During the disease, acute eczema (eczema acutum) and chronic (eczema chronicum) are distinguished. In the first case, the surface layers of the skin are mainly involved in the process, in the second - the surface and deep layers. In the chronic form of eczema, the skin of the auricle and the external auditory meatus thickens, as a result of which its lumen narrows significantly, cracks appear at the entrance to the external auditory meatus.

In childhood, the weeping form of eczema is more common, in adults, weeping and dry; with the latter, profuse peeling of the epidermis of the skin occurs.

K l and n and with to and to kartin and. The initial stage of acute eczema is characterized by hyperemia, thickening of the skin of the auricle and the external auditory canal due to infiltration. The auditory meatus sharply narrows. Patients complain of constant and painful itching in the ears. As a result of scratches, abrasions and scratches occur. Small vesicles with serous contents appear, when they spontaneously open, their serous fluid flows out, and weeping appears.

Contact of the liquid with air leads to the formation of grayish-yellow crusts. Joining a secondary infection leads to the development of limited or diffuse external otitis media.
In the presence of common diseases in a patient, eczema takes a chronic course and the process spreads deep into the skin. The disease often recurs.

D and a g n about with t and to and is based on the data of the anamnesis and clinical symptoms (redness, thickening of the skin, weeping, peeling or peeling). The acute form must be distinguished from erysipelas of the outer ear, otitis externa, and fungal infection of the outer ear. With erysipelas, there is no itching, palpation of the affected area is sharply painful, the border of inflammation is clear. With eczema, the opposite is observed. The fungal process is diagnosed with the help of a special mycological examination, in particular, the study of scraping from the skin of the ear (native preparation) under a microscope and culture cultures on nutrient media to identify the type of fungus.

Treatment. Eczema therapy involves the treatment of the underlying disease that caused eczema. Of the general funds, antihistamines (zaditen, etc.), immunomodulators (prodigiosan, etc.) are prescribed. A daily hygienic toilet of the affected area is produced daily with ether or alcohol (without water). To mitigate itching, dusting with talc or zinc oxide is used. A good therapeutic effect with a wetting form is provided by daily irrigation of the affected skin with oxycort aerosol. When peeling, ointments are prescribed - oxycort, hecorton, celestoderm, etc., which give a good result. Apply a 1.5% solution of brilliant green, zinc ointment with fish oil, 3% yellow mercury ointment, ointments with ichthyol, ASD (5%), etc.

Crusts are removed after preliminary softening with vegetable or liquid paraffin, then oxytetracycline or prednisolone ointment is applied.

Medication is combined with physiotherapy - UV irradiation in suberythemic doses and UHF. Particular attention should be paid to the general condition of the patient, especially the child. Prevention of eczema consists in eliminating all the irritating factors that contribute to the development of dermatitis. Washing of the ears with water should be excluded, since it worsens the course of the process, strictly observe hygienic care of the ear during suppuration from the middle ear in acute and chronic otitis media. It is necessary to rationalize nutrition, to treat common diseases (intestinal, metabolism, etc.).
