Eczema of the external auditory canal has the possibility of self-healing, but most of them need to be treated through general therapy, medication, etc., but the specific efficacy varies from person to person. Eczema of the external auditory canal is an inflammation of the superficial dermis and epidermis of the external auditory canal caused by a variety of internal and external factors. Clinically, the lesions in the acute stage are dominated by herpes papules with a tendency to ooze, and in the chronic stage are dominated by mossy lesions, which are prone to recurrent episodes. Some of the milder eczema of the external auditory canal may be self-healing after the allergic stimulus is removed in a timely manner. For those with more exudate, 3% boric acid solution or 15% zinc oxide solution can be used as wet compresses. If there is little or no exudate, 1% to 2% methyl violet liquid, prednisone cold cream or ointment, zinc oxide oil or paste can be applied. If there are dry scabs, 3% hydrogen peroxide solution can be used to wash and wipe dry, apply the above liquid or ointment. Chronic eczema with skin thickening or cracking, 10% to 15% silver nitrate can be used to rub; between episodes, 70% ethanol solution can be used to clean the external auditory canal, to keep it dry. Anti-allergic drugs such as chlorpheniramine and loratadine tablets can be taken, and glucocorticosteroids such as dexamethasone can be used in severe cases; local and systemic antibiotics can be used to fight infection; fluid can be replaced in time when there is much exudate and vitamin C can be supplemented. If you have symptoms related to external auditory canal eczema, it is recommended that you consult a doctor in time to determine the cause of the disease and follow the doctor’s instructions to standardize the use of medication and treatment.
