A basilar fracture is a type of skull fracture that occurs at the base of the skull. This injury often results from significant trauma, such as a car accident or a fall. Symptoms may include bruising around the eyes or behind the ears, clear fluid leaking from the nose or ears, and neurological issues. Diagnosis typically involves imaging tests like a CT scan or MRI. Treatment depends on the severity of the fracture and may include observation, medication for pain, or surgery in more serious cases. Complications can include cerebrospinal fluid leaks and damage to cranial nerves.
