Earlobe sebaceous cysts are relatively common body surface swellings in clinical practice. In the case of infected sebaceous cysts, incision and drainage of the cyst is performed to allow for re-excision in a second-stage surgery after the infected lesion has recovered. In some cases where the sebaceous cyst in the earlobe is small and there are no obvious symptoms, no special medication or treatment can be used for the time being. For those sebaceous cysts that grow larger and affect the aesthetics, it is best to remove and suture them without infection. The removal may have some effect on the earlobe and infection must be prevented after surgery. Because the earlobe is the end of the limb, the blood circulation is not particularly rich and the ability to resist infection is particularly poor, so it is important to disinfect the area regularly after surgery to promote healing of the incision so that infection does not cause the possibility of sebaceous cyst recurrence. Therefore, if you have an earlobe sebaceous cyst, you must go to a regular hospital for surgical treatment.
