How to repair the failure of earlobe plastic surgery? Experts from Plastic Review Network said: Cartilage tube method is often used to repair the plastic failure of ears. The basic principle of repair is to restore the shape of the antihelix and its upper foot and narrow the concha cavity. 1. Fixed-point design for repairing failed ear plastic surgery (1): Fold the auricle to the head side with thumb and forefinger, exposing the auricle boat, the antihelix and its upper foot, make obvious marks on the skin in front of the ear with methylene blue, and pierce the auricle backwards from the front of the ear with an injection needle containing methylene blue according to the contour, leaving obvious marks on the skin and cartilage surface before and after the auricle, which is convenient for intraoperative identification. (2) Treatment of skin and cartilage: make a shuttle-shaped incision behind the ear, and separate it to both sides on the perichondrium to expose the methylene blue coloring points marked on the perichondrium. Cut the cartilage point by point, but don't cut the anterior perichondrium, and gradually sew the cartilage into a tube with thin lines from bottom to top. In this way, the shape of helix and upper horn can be formed on the side of the ear, and the narrow part of the lower end of cartilage can be left unstitched. For people who have lost their left foot, they can also make all the mouths of their left feet. Finally, the excess skin behind the ear is removed and sutured. It is best to stagger the suture between skin and cartilage during operation to reduce the chance of ear cartilage infection. Before and after filling the auricle with loose wet gauze, use pressure dressing to maintain the normal position and shape of the auricle to prevent the formation of hematoma. 2. Complications of auricle surgery (1) Infection: It is a serious complication of auricle surgery. Light affects the cosmetic effect, and severe cases have full auricle periostitis, resulting in auricle necrosis and deformity, with serious consequences. Preventive measures: In order to prevent infection complications after ear pulling, anti-inflammatory measures must be strengthened before, during and after operation. Especially if the auricle hematoma is not handled properly after operation, it can cause secondary infection, which makes the surgical effect completely wasted. (2) Correcting bilateral auricle asymmetry: Bilateral auricle asymmetry after suture is mostly due to preoperative design errors. III. Precautions for Complications of Ear Pulling (1) Thoroughly analyze the shape of auricle before operation, formulate appropriate design scheme, closely observe during operation, and follow up regularly after operation (2) Correct the side that has occurred and is insufficient, and perform a second operation after operation 1 year.
