Examination reveals redness and swelling of the external ear canal secretions, which require the use of antibiotic ear drops and, in severe cases, oral antibiotic treatment. 2. Fungal infections of the external ear canal, which are very widely distributed and are also prone to fungal cross-infection due to the lack of strict or unsterilized disinfection of instruments during ear picking.
