Which radiographic projection is specifically used to view paranasal sinuses?

The lateral cephalometric projection is specifically designed to visualize the paranasal sinuses along with other anatomical structures of the skull. This type of imaging is particularly useful in assessing the overall anatomy of the facial skeleton, including the maxillary, frontal, ethmoid, and sphenoid sinuses.

Lateral cephalometric radiography provides a side view of the skull, which allows for clear visibility of the sinus cavities and helps in diagnosing conditions such as sinusitis, anatomical variations, and other sinus-related issues. This projection is also beneficial in orthodontics and oral surgery planning.

In contrast, the periapical projection primarily focuses on individual teeth and surrounding bone, while the bitewing projection is used to view the interproximal areas of the teeth and check for caries or bone loss. The panoramic projection offers a broad view of the entire jaw and teeth but is less specific for sinus evaluation than the lateral cephalometric view.
