**Core Concept**
Skull base fractures are a type of traumatic injury that involves the bones forming the base of the skull. These fractures can be complex and may involve multiple structures, including cranial nerves, blood vessels, and sinuses.

**Why the Correct Answer is Right**
Skull base fractures are often associated with significant morbidity and mortality due to the critical structures that are at risk. The correct answer is related to the consequences of skull base fractures, which include **carotid-cavernous fistula** (a connection between the carotid artery and cavernous sinus), **cranial nerve palsies**, and **cerebrospinal fluid (CSF) rhinorrhea** (leakage of CSF through the nose). These complications can arise due to the direct injury to the cranial nerves and blood vessels in the skull base.

**Why Each Wrong Option is Incorrect**
**Option A:** Not a direct consequence of skull base fracture. **Option B:** Associated with skull base fracture, as it can lead to CSF rhinorrhea. **Option C:** Not a direct consequence of skull base fracture.

**Clinical Pearl / High-Yield Fact**
Skull base fractures are often difficult to diagnose on plain radiographs, and CT scans with thin sections are usually required for accurate diagnosis.

**Correct Answer:** C
