Judging from the photos, there is no need for cosmetic surgery. As for whether there will be scars, it depends on whether the child's skin fits or not. This is because everyone's physique is different, and skin healing means that the wound is firm and fast, so I suggest you give your child some vitamins, apply anti-inflammatory and antibacterial drugs to the wound or go to the pharmacy to buy drugs to promote wound healing. When the wound is about to heal, it is basically no problem to rub some aloe vera gel on the wound. Good luck.
