**Core Concept**
Temporal bone injuries often involve complex fractures and potential damage to vital structures such as the facial nerve, carotid artery, and inner ear. Accurate diagnosis and assessment of temporal bone injuries require a combination of clinical evaluation and imaging modalities. High-resolution imaging is essential to identify the extent of bony and soft tissue damage.

**Why the Correct Answer is Right**
High-resolution computed tomography (CT) scans are the investigation of choice for temporal bone injuries. This is because CT scans provide detailed images of the bony structures and can detect subtle fractures, dislocations, and soft tissue damage. CT scans can also help identify potential complications such as facial nerve paralysis, hearing loss, or vascular injury. The high-resolution images obtained from CT scans enable accurate assessment and planning of treatment for temporal bone injuries.

**Why Each Wrong Option is Incorrect**
**Option A:** Magnetic Resonance Imaging (MRI) may be useful in evaluating soft tissue injuries, but it is not the primary investigation for temporal bone fractures due to its lower sensitivity for bony abnormalities.

**Option B:** X-rays are not sufficient for evaluating temporal bone injuries, as they may not detect subtle fractures or soft tissue damage.

**Option C:** Temporal bone injuries often require a more detailed assessment than provided by plain radiographs, making X-rays an inadequate choice.

**Clinical Pearl / High-Yield Fact**
When evaluating patients with suspected temporal bone injuries, it is essential to consider the clinical symptoms and signs, such as hearing loss, facial weakness, or jaw pain, in conjunction with imaging findings to ensure comprehensive assessment and management.

**Correct Answer: C. X-rays**
