Severe cranial injuries, such as those that cause hemorrhage and bleeding, and produce epidural hematoma, at this point will be life-threatening, requiring neurosurgeons to perform an emergency craniotomy to save lives; in addition to depressed cranial fracture, which may puncture the blood vessels of the cerebral cortex and produce an intracerebral hematoma, which can endanger the patient’s life or cause disability; if it is a simple linear fracture that does not cause intracranial hemorrhage, the patient is still relatively safe . Cranial repair does not affect a person’s natural life expectancy, how long you can live still depends on this natural life expectancy of the human body. Cranial repair surgery is very helpful to the recovery of patients with cranial defects, so we still recommend early and early cranial repair surgery. For the question of how long it takes to recover from cranial bone repair surgery, cranial bone repair surgery should be measured from several aspects of preoperative and postoperative time. First of all, before the skull repair surgery, it takes 4 working days to prepare the repair material, while the patient has to undergo preoperative examination, including head CT, blood sampling, biochemistry, chest X-ray, relevant ultrasound and so on. Secondly, the surgery takes about 2 hours to complete if the operation goes well. On the second day after the operation, the drainage tube can be removed and the patient can move off the ground. If the recovery is smooth, you can be discharged from the hospital on the seventh day after the operation. Basically, cranial repair surgery can be completed 4 days before surgery and about 7 to 8 days after surgery.
