Bifrontal cerebral contusions, including cerebral contusions and cerebral lacerations. If the brain parenchyma alone is damaged and the soft meninges remain intact, it is like a watermelon with the rind intact and the flesh destroyed, a cerebral contusion. If the brain parenchyma is broken and the soft meninges are torn, it is like a watermelon rind with the flesh broken, which is a brain laceration. Because brain contusion and brain laceration often exist at the same time, they are synthesized as brain contusion laceration. Treatment of cerebral contusion laceration, cerebral contusion laceration is not serious, generally to non-surgical conservative treatment, nourishing the brain nerve, reduce brain edema. Ice caps are used to reduce cerebral metabolism and oxygen consumption of the brain, and effective oxygen therapy. Hyperbaric oxygenation is available in stable conditions. Those with secondary intracranial hematoma or uncontrollable intracranial hypertension require surgical treatment.
