Which of the following is NOT an evaluation criterion for the submentovertex (SMV) projection?

In the context of the submentovertex (SMV) projection, the evaluation criteria are focused on the proper alignment and visibility of specific anatomical structures. The SMV projection is primarily utilized to visualize the base of the skull and the mandible.

The criterion pertaining to the superimposition of the nasal bones is not applicable for the SMV projection, which aims to accentuate structures such as the petrosae, the mandible, and other features of the cranial base. Instead, the superimposition of the nasal bones is more relevant to other projections that concentrate on the anterior aspects of the face.

On the other hand, the other choices correspond to important evaluation criteria for the SMV projection. For instance, symmetric petrosae indicate correct positioning of the head, ensuring even visibility of the structures on either side, while the position of the mandibular condyles being anterior to the petrous pyramids confirms the appropriate angulation. Additionally, achieving equal distance from the skull to the mandibular condyles helps to maintain the accuracy of the imaging, reflecting proper positioning of the patient's head during the radiographic procedure.
