What is the treatment for acute otitis externa?

If a patient has swelling of the external auditory canal with purulent discharge, the pus should first be thoroughly cleaned, followed by treatment with antibiotic ear drops and application of antibiotic ointment to the affected area. If the patient also has symptoms such as fever and general weakness, oral antibiotics such as cephalosporins or azithromycin should be administered. In daily life, avoid spicy and irritating foods, abstain from alcohol, and prevent water from entering the ears during bathing. With comprehensive treatment, recovery usually occurs within 7–10 days.
