In clinical practice, there is no doctrine that the anterior, middle, or posterior cranial fossa is susceptible to damage. If we look at the clinical manifestations, the cranial middle fossa is relatively more likely to be damaged, but it does not completely indicate that the cranial middle fossa is the most vulnerable. However, it is not entirely clear that the cranial fossa is the most susceptible to injury, because it is determined by the direction of the force, the location of the force, and the magnitude of the force. Generally speaking, for frontal injuries, many of them will have changes in the anterior cranial fossa, such as directly hitting the wall with the head, and many of them are fractures of the anterior cranial fossa. For lateral injuries, such as being struck from the side on the temple, it is easy to cause injury to the middle fossa of the skull. And if the back of the head lands on the ground, it can again damage the posterior cranial fossa. Each injury mechanism is different, and each relative probability of injury is different, and must be judged on a case-by-case basis.
