Which projection uses the Waters method to image the nasal bones?

• A. Lateral projection
• B. PA axial Caldwell
• C. Parietoacanthial projection, Waters method
• D. SMV projection

Answer: (C)

For imaging the nasal bones, the Waters (parietoacanthial) projection is used. This position tilts the midface so the nasal bones lie in a plane that the X-ray beam passes through with minimal overlap from the frontal bone and the orbits. By having the chin tucked and the face angled, the nasal bones are centered in the image and shown with good detail and less superimposition, making this view the best choice for assessing nasal bones. Other views exist (like a lateral) but they don’t employ the Waters technique and aren’t as optimized for the nasal bones.
