Red, swollen, painful, and feverish ears are commonly associated with purulent auricular chondromyelitis, which may be related to external factors such as surgery, frostbite, trauma, bruises, and burns, and is dominated by Staphylococcus aureus and Pseudomonas aeruginosa infections. This lesion is very aggressive, attacking the auricular skin, subcutaneous tissue, cartilage, and perichondrium, and infection of the entire auricle can occur. Generally, blood sampling for routine blood tests such as white blood cells will be significantly elevated, and the patient will develop auricular redness, pain, and fever, which is limited in scope in the early stage and can expand to the entire auricle in the later stage, and can even form a fluctuating sensation and surface abscess formation. In order to avoid the formation of cauliflower ear, it is necessary to apply a sufficient amount of antibiotics, local incision and drainage treatment and drug changes.
