basilar skull fracture is a type of traumatic brain injury that causes a loss of continuity of bone at the base of the skull. If not treated properly, basilar skull fractures can be fatal.

Cerebrospinal fluid leakage is the leakage of cerebrospinal fluid from the skull to the outside through the ears or nose. Cerebrospinal fluid leakage after trauma is a common complication. Cerebrospinal fluid leakage through the nose can cause complications such as rhinitis, nasal infection, encephalitis and meningitis.

Cerebrospinal fluid leakage at the base of the skull is a rare condition and difficult to treat surgically. However, in recent times, with the advancement of endoscopic techniques, this condition can be performed in a less invasive manner while still ensuring effective treatment, and the postoperative process has also become simpler. Since then, the patient's life has also been significantly improved, significantly reducing the risks associated with cerebrospinal fluid leakage.
