But there is one thing to note, most of the large skull defects in children can not grow up by themselves, parents should pay attention to it. Moreover, cranial defects in children are not less harmful than those in adults, and long-term cranial defects in children will affect the child’s brain development and cause a series of cranial defect syndrome in children, plus children are more active, so the risk of secondary injury is higher if cranial defects are not treated. In addition, if the child’s skull defect is not treated in time, the skull shape will be changed, which will also have a certain impact on the child’s psychology.
