In recent years, a variety of large-scale traffic accidents occur more frequently, and it is also because of the accidental car accidents, causing heavy craniocerebral injuries and craniocerebral hemorrhage, etc., which is a great threat to life and health, at this time the need to do is to do a craniotomy in a timely manner, in order to control intracranial hemorrhage, to save the patient’s life. However, usually during craniotomy, a window is opened in the skull and a bone flap decompression surgery is performed, which can help to reduce intracranial pressure, reduce the pressure on the intracranial tissues, so that the surgeon can better stop the bleeding inside the skull, clear the hematoma, and minimize the damage as much as possible. Can I return to normal with debridement surgery? Some patients with severe craniocerebral injuries, even coma, etc., through the decompression surgery can play a certain role in alleviating the improvement, but the specific recovery will depend on the individual patient’s own physical quality, healing ability, and whether there are infections after the operation, and so on. In addition, because the flap decompression surgery is a window in the skull, the skull defect will remain after the surgery. Patients need to be aware that cranial defects should be taken equally seriously; after all, the skull is an external protective barrier for the brain, and prolonged cranial defects that are not repaired can cause more impact on the patient. Therefore, it is generally recommended that patients who undergo debridement go to the hospital for cranial bone repair surgery about 3-6 months after the surgery, so as to remodel the complete and closed cranial cavity environment, and to help restore the normal functioning of all intracranial life activities.
