Fractures are seen in both the anterior, middle, and posterior cranial fossae, usually as a result of significant violence to the head, and the clinical signs are characterized by significant soft-tissue contusions of the skin, bruising, bruising, and swelling in the orbital, temporal, retroauricular, and parieto-occipital regions. In addition, oozing of cerebrospinal fluid is seen in the nasal cavity, mouth, or external auditory canal, and the cerebrospinal fluid is usually mixed with blood and is pale or dark red bloody fluid. Most of them may be combined with pneumocephalus or intracranial tissues showing damage or bleeding, etc. A cranial CT as well as a thin CT scan of the base of the skull must be done to make a complete and definitive diagnosis. If the fracture is purely in the anterior, middle or posterior cranial fossa, the fracture can usually heal gradually with proper hemostasis and pain relief, combined with infection prevention.
