The parents were worried about encephalitis and went to the hospital to check the child’s symptoms and found that the child had smog. Most children are found to have smog only after a TIA or a brain attack, so this child’s case is one of the most unfortunate. The child had already undergone surgery on one side for smog, and considering the lesion on the opposite side, it was recommended to perform surgery on the other side to reduce the risk of smog affecting the patient. In addition, we also explained the problem of the surgical incision, which is large but hidden in the hairline, so the child’s hair will not have a great impact on the aesthetics when he grows up, and the parents may not be aware of this problem at the moment. We will consider whether the surgery will affect the patient’s quality of life, the post-operative care and the discharge of the patient’s family, and whether the surgical incision will affect her aesthetics.
