Question

Quizplus · Accepted Answer

The AP axial projection of the zygomatic arches is performed with the patient's head in a true lateral position, and the x-ray beam is directed 25-30 degrees cephalad. The orbitomeatal line is placed perpendicular to the image receptor in this projection. The mentomeatal line and acanthiomeatal line are used for other projections, and the infraorbitomeatal line is not relevant for this specific projection.
