Facial Bones

What is the routine done for facial bones? Waters (parietoacantial), hard lateral, soft lateral, caldwell, SMV (zygomatic arches)
Where does the CR exit on the waters facial bones? Exits the acanthion
What is the patients position for the waters facial bones? patient is prone or seated. Chin rested on table. MML perpendicular. OML forms 37 degree angle to film

What is demonstrated in the waters facial bones? Petrous ridges below maxillae, orbits, maxillae and zygomatic arches
What is the difference between the hard lateral and soft lateral facial boens? Hard lateral we are demonstrating all the sinuses and in the soft lateral we are demonstrating the soft tissue of the nasal bones, nasion and acanthion
