Description: How can even slight variations in patient positioning affect the geometry, symmetry, and diagnostic reliability of a panoramic radiograph?

Patient positioning is one of the most critical factors in determining the accuracy of a panoramic radiograph. Even variations of just a few millimeters can significantly change the final image. Because panoramic imaging depends on anatomical structures remaining within a narrow focal trough as the unit rotates around the patient, any spatial misalignment can create geometric distortions that directly affect diagnostic interpretation.

When the patient is positioned too far forward or too far back, the resulting radiograph may show disproportionate narrowing or widening of the anterior teeth. Similarly, lateral rotation of the head away from the midline can produce noticeable asymmetry between the right and left sides of the image.
