Nasal bones
Right and left laterals with a small focal spot and low technique, centered just below the nasion; Waters for the septum.
Patient and part
Nasal bone images are taken after a blow to the nose. The routine is a lateral of each side, right and left, and a frontal view, usually a Waters, to show sideways displacement and the septum. For the laterals, the patient is erect or prone with the head in a true lateral: MSP parallel to the IR, interpupillary line perpendicular. Both laterals are taken because the side closer to the IR shows sharper.
