Hormonal drugs: If the keloid scars on pierced ears are small and grow slowly, hormonal drugs such as compound betamethasone or tretinoin injection can be used for local injection to inhibit the keloid scars 2. Surgical excision: If the keloid is large and growing fast, surgery should be performed as soon as possible to prevent the keloid from growing too fast and too large and removing too much tissue to cause deformity of the ear; 3. Radiotherapy: After surgical excision, local radiotherapy can be done to inhibit the formation and growth of the keloid and avoid recurrence, the earlier the radiotherapy, the better the effect. Ear piercing keloid will affect the aesthetics, and the beauty seekers should not handle it by themselves to avoid accidents such as bleeding more than once. It is recommended to go to the local regular hospital for consultation and use the method of removing the keloid reasonably under the guidance of the doctor.
