**Core Concept**
The assessment of zygoma fractures requires a thorough understanding of facial anatomy and the use of specific radiographic views. The zygomatic bone is a complex structure that forms the prominence of the cheek and the lateral wall of the orbit.

**Why the Correct Answer is Right**
Zygoma fractures are best visualized on a coronal CT scan of the face. This is because the coronal plane provides a clear view of the zygomatic bone's complex anatomy, including its articulations with the frontal, maxillary, and temporal bones. The coronal view helps to assess the integrity of the orbital floor, the zygomatic arch, and the zygomaticomaxillary complex.

**Why Each Wrong Option is Incorrect**
**Option A:** A lateral skull X-ray may show some aspects of zygoma fractures, but it is not the best view for comprehensive assessment.
**Option B:** An occipitomental (Water's) view is useful for assessing maxillary fractures but is not ideal for visualizing zygoma fractures.
**Option C:** A submentovertex (SMV) view may provide some information about the zygomatic arch but is not the best view for assessing zygoma fractures.

**Clinical Pearl / High-Yield Fact**
When assessing zygoma fractures, it's essential to remember the "4 corners" of the zygomatic bone: the frontal process, the maxillary process, the temporal process, and the orbital process. Each of these areas should be carefully evaluated on the coronal CT scan to ensure accurate diagnosis and treatment planning.

**Correct Answer: C. A coronal CT scan of the face.**
