The ability to recover from craniotomy depends largely on the severity of the primary disease. There are some diseases in neurosurgery that can recover well after craniotomy, some of which can completely return to normal life, such as epidural hematoma, cerebellar hemorrhage, simple ventricular hemorrhage, minor cerebral contusion, and certain intracranial tumors. However, for certain serious intracranial lesions, it is very difficult to return to normal after craniotomy, such as severe cerebral hemorrhage, severe cerebral contusion, malignant intracranial tumors and other cases. Recovery is more difficult because of more nerve damage, and it may be difficult to maintain the patient’s life after surgery.
