As spring blossomed, many women started to dress up, and 25-year-old Xiao Li got her ears pierced to make herself look more individual. After a few days, the newly pierced ears started to become red and flowing, and the ears were swollen and painful. After a month, the discomfort didn’t go away and a red pimple the size of a soybean grew on her ear. After seeing a doctor, she learned that these bumps are called scars, which are caused by the use of unclean utensils for ear piercing, or the lack of hygiene when wearing earrings or earrings studs, as well as the rough handling of the earrings and earrings, which break and bleed and become infected, and some people already have scars and have their ears pierced to form scars. These scars tend to be hemispherical in shape, and some even look like ping pong balls hanging from the ears. For these scars, local glucocorticoid injections and laser treatment have little effect. We have achieved good results using kernel excision of scars combined with intraoperative glucocorticoid injection and postoperative superficial local x-ray irradiation. Compared with traditional excision, kernel excision only removes the inner fibrous tissues of the scar and preserves the surface skin tissues, which provides conditions for maintaining the shape of the ear. Also, because the surface skin tissue is preserved, it can completely cover the defect formed during surgery, thus truly achieving tension-free suture and reducing the chance of scar recurrence after surgery. In addition, the combination of glucocorticoid injection and local radiotherapy adds another double insurance to prevent the recurrence of scars, which greatly reduces the chance of recurrence of scars.
