Patients who have a hard bump around the ear need to clarify the nature of the swelling. If it is caused by inflammation, patients are advised to actively fight inflammation and reduce swelling. Cefdinir dispersible tablets are commonly used clinically, and you can also apply chlortetracycline ointment around the ear, or compound polymyxin B ointment for anti-inflammatory purposes. If a swelling develops, it is often necessary to determine the benignity or malignancy of the swelling and, if necessary, to obtain pathology or perform cytocentesis. After the benignity of the swelling is determined, further treatment can be done. In benign cases, the swelling can be removed directly, while in malignant cases, radiotherapy can be considered or the swelling can be removed directly. Postoperative consolidation treatment with radiotherapy can effectively reduce the chance of recurrence of malignant tumors. After active treatment, the patient’s condition will be significantly improved.
