What symptom may indicate a basilar skull fracture?

Clear fluid leakage from the nose or ears is a significant symptom that may indicate a basilar skull fracture. This leakage often occurs because a fracture in the base of the skull can cause damage to the membranes surrounding the brain, leading to cerebrospinal fluid (CSF) leakage. The fluid is typically clear, resembling drainage seen in conditions like a runny nose, and is a critical sign that healthcare providers look for when assessing potential skull fractures.

Basilar skull fractures can also be associated with other signs, such as bruising around the eyes (raccoon eyes) or behind the ears (battle sign), but the presence of clear fluid indicates a breach in protective barriers around the brain and can suggest a more serious injury. Immediate medical evaluation is essential in these cases to address the risk of infection and other complications associated with CSF leakage.
