Surgery for craniocerebral trauma caused by car accidents is relatively simple in itself, with a success rate of over 95%. Only a small percentage of patients are in a state of frequent death before surgery, and their condition is so severe that they may die on the operating table during surgery, resulting in surgical failure. However, successful surgery does not mean a good prognosis. The prognosis of craniocerebral trauma caused by car accidents is closely related to the severity of the condition. If the patient’s condition is extremely serious before surgery, with bilateral pupil dilatation and late brain herniation, even a successful surgery may not save the patient’s life. If the patient is clear before surgery, he or she will recover well after surgery.
