After the onset of the disease, fluid can be repeatedly punctured and extracted under aseptic operation, and after the fluid is extracted, flumethasone is injected, and in order to prevent the recurrence of fluid accumulation, local pressure bandages should be applied. In order to shorten the treatment time, a small window can be opened in the whole layer of the cyst wall under strict aseptic operation, and after the fluid is discharged, the local pressure bandage can be healed within a week. After the disease, keep local cleanliness and do not apply medicine indiscriminately to avoid secondary infection and septic chondromalacia and auricular deformity. The principle of radiofrequency treatment is to use low-frequency electromagnetic waves to act on human tissues, producing endogenous heat effect, using a lower temperature to make tissue protein coagulation, through thrombosis to make the affected area vascular occlusion, tissue atrophy necrosis off, to achieve the purpose of healing. Because of the small trauma of radiofrequency treatment, recovery is fast, so, generally after the treatment rest ten minutes can go home, go home to pay attention to prevent wound infection, shampoo and shower to avoid sewage into the wound and inflammation, back to the hospital every day to change medicine, about a week to heal. The next thing is to observe whether the wound is bleeding and whether the dressing is freshly blood-stained, avoid lying down towards the affected ear when sleeping, generally the scabs fall off at the RF in about a week and gradually recover, at this time, ear digging should be prohibited to avoid wound bleeding and infection.
