Sebaceous cysts and keloids are common. 1. Sebaceous cysts: If the hair follicles in the ear bone holes are blocked and sebum accumulates into cysts, sebaceous cysts may be formed. If the cyst is small and has no other symptoms, there is usually no need to deal with it; larger cysts need to be removed completely by surgery. 2. Cysts combined with bacterial infection: local redness, swelling and pain may also occur, can be disinfected with iodophor or alcohol disinfection every day, and then coated with mupirocin ointment twice a day, if necessary, should be combined with oral amoxicillin and other anti-inflammatory drugs anti-infection treatment. 3. Keloid: small keloid is generally recommended conservative treatment, local injection of long-acting glucocorticoids, such as trimethoprim; medium and large tumor type keloid is recommended surgical treatment, general surgical resection with local radiation therapy. If the ear bone hole on the bulging bag, should promptly seek medical attention to identify the cause of the disease, under the guidance of the doctor for treatment.
