Children who fall on their heads and collapse usually do not have deformed brains, but they still need to be taken seriously. Usually the main consideration for children who fall on their head and cause it to collapse is a skull fracture. Usually after the skull cap is hit by external force, the violence is fast, the area of action is small, and does not exceed the elastic range of the skull, then rebound will occur without obvious depression. If the elastic range is exceeded, the center of gravity will be plunged conically into the cranial cavity, triggering bone rupture. However, localized deformation of the skull does not usually affect the shape of the brain, and if the injury-causing force is not exhausted, the skull may be plunged into the cranial cavity, and comminuted depressed or cavernous fractures may be formed. Cavity fractures are generally less likely to result in diffuse brain damage, and are more likely to be characterized by localized neurological deficits. Parents are advised to bring their children to the doctor for timely examination and actively cooperate with the doctor to take targeted treatment in case of head collapse to avoid delay.
