An abscess in the earlobe is mainly an infection secondary to sebaceous cyst obstruction. Early on, it is a powdery tumor, manifesting as a regular, intact swelling with regular margins, which can be accompanied by mild tenderness. If not treated promptly and effectively, it can lead to infection within the tumor, and the patient can develop a fever and a feeling of significant local fluctuation. In this case, surgery for incision and drainage should be chosen in a timely manner, which can usually be performed under local anesthesia. Regular drug changes are required after surgery, and each time the drug change is performed, the pus cavity should be thoroughly explored to remove the pus moss and secretions and keep the drainage open. Local filling with iodophor gauze can also be applied, which can inhibit the growth of bacteria and promote local healing of the wound to a certain extent. During the treatment and recovery period, attention should be paid to the supplementation of high-protein foods and foods rich in vitamins.
