How should the head be positioned to best demonstrate the body of the mandible in an axiolateral projection?

To best demonstrate the body of the mandible in an axiolateral projection, the head should be rotated 30 degrees toward the affected side. This rotation is critical because it optimally positions the mandible, allowing for clearer visualization and reducing superimposition of other anatomical structures.

In the axiolateral projection, the central ray is directed 25 degrees cephalad, which, in conjunction with the 30-degree head rotation toward the affected side, creates an ideal profile of the mandible. This orientation provides adequate separation of the mandible from surrounding structures, enhancing the diagnostic quality of the image.

Understanding the angle of rotation is essential because improper positioning can obscure important anatomical details, leading to misinterpretation of the images. Thus, a 30-degree rotation toward the affected side is the appropriate choice for achieving a clear view of the body's mandible in this projection.
