Question

Caldwell's view is used for:

• A. Maxillary sinus
• B. Frontal sinus
• C. Ethmoidal sinus
• D. All of the above

Hint:

Occipitofrontal 20 degree view best shows the frontal sinus.

Answer 1

The Correct Option is B

Step 1: Caldwell's view, also called the occipitofrontal view, is a radiographic projection of the skull for sinus assessment.
Step 2: The X-ray plate is angled at \(20^\circ\) to the orbitomeatal line, with rays passing from behind the head perpendicular to the plate.
Step 3: This angulation projects the petrous ridges into the lower orbit and gives the best view of the frontal sinuses, with the ethmoid air cells also reasonably shown.
Step 4: The maxillary sinuses are better demonstrated on the Waters' view, so the single best answer here is frontal sinus.
