People pray for peace, but fate can sometimes be contrary to their wishes, and many people suffer a traumatic brain injury due to a sudden accident. If the problem of cranial trauma is very serious, it may require timely surgery. However, some patients’ lives are saved after craniocerebral trauma surgery, but their skulls are damaged, and cranial defects should not be underestimated. If the skull defect diameter is larger than 3cm after craniocerebral trauma, the patient will often have headache and dizziness, be easily agitated, and have local fluctuation in the defect area. Moreover, the skull defect directly affects the aesthetics, and the patient will have low self-esteem and will be depressed for a long time. If there is no contraindication to surgery, cranial repair surgery is recommended to be performed 3 months after cranial trauma. The purpose of cranial repair surgery is to reconstruct a complete and closed cranial cavity, restore a stable intracranial operating environment, and ensure the cerebrospinal fluid circulation, blood circulation, and neurological functions of the brain.
