If the earlobe is splitting from the face, the main thing to look at is the size of the splitting wound and decide on a treatment plan. If the splitting is small, with a wound less than 0.5cm, the wound is usually given a strict disinfection and then bandaged, waiting for it to heal gradually. If you want to make the wound heal faster, you can spray topical recombinant epidermal growth factor after disinfection, which can promote the growth of epidermis and can facilitate the healing of the wound. If the wound is larger than 0.5cm, it must be given a wound debridement suture. Generally, if you want to have a smaller local scar, it is recommended to use collagen thread, so that the scar will be as small as possible, and there is no need to remove the thread, because the collagen thread will be absorbed by the body and the thread will fall off by itself.
