Generally speaking, the repair of post-traumatic scars is selected more than half a year after injury. Because it takes half a year for scars to go from proliferative phase to regressive phase, and then to stable phase. For young children, especially facial trauma, in principle, we should also consider the physical and psychological endurance for half a year after the injury. 1. Too young children are extremely afraid of surgery, unable to cooperate with local anesthesia surgery, and need to be hospitalized for general anesthesia surgery, which adds trouble to themselves and their families. 2. After children go to primary school, they are often laughed at by their classmates because of facial scars, which will lead to inferiority complex. Therefore, it is the best choice if children can tolerate outpatient local anesthesia surgery before school age. If you can't stand it, you should be hospitalized for half a year for general anesthesia after the injury.
