How many years can I live without repairing my skull? The skull is one of the hardest bones in the human body and plays an important role in protecting the brain tissue inside the skull and maintaining the intracranial environment. If an accident occurs that results in a skull defect, then cranial repair should be performed in a timely manner. Many patients with cranial damage ask if it is possible to repair the cranium without repairing it. How long can I live if the skull is not repaired? Theoretically, as long as the brain tissue at the site of the defect is not affected, it is possible to go without cranial repair. In practice, however, there is no way to ensure that the damaged part of the brain tissue is in a normal healthy state. Without the protection of the cranium to the brain tissue, even without the stimulation of external conditions, the human body’s own scalp and hair will spread, contact and cover the brain tissue directly, and the brain tissue will be shifted for a long time with the change of the body position, resulting in the alteration of the blood circulation of the brain, or due to the adhesion of the scalp and the dura mater shifting, so that the subarachnoid space disappeared and the cerebral cortical perfusion was reduced, and the foci of the softening of brain tissues under the window of the bone increased, which can form the traumatic cysts , brain penetrating deformity, ventricular asymmetry and so on. The more direct manifestation is that the patient has headache and dizziness, afraid of sunlight and noisy, not only has the psychological shadow such as inferiority complex and depression, but also may cause memory loss, inattention and so on. Therefore, cranial repair is not only for the beauty of the patient’s head, but also for the patient’s life and health. Of course, the material of cranial bone repair is also a very important one, at present, the clinical use of new polyether ether ketone PEEK material as cranial bone repair material. The PEEK material uses bionic material with the highest affinity to human bones, and the three-dimensional reconstruction highly restores the structure of the skull, so that the damaged parts and the original bone window fit beautifully, not only looks exactly the same, but also accelerates the development of the bone healing, which is worth the patient’s first choice of the better repair material.
