Facial Bones

Waters, Caldwell, Lateral

For a lateral projection of the facial bones, the IR is centered to the: zygomatic bone
What baseline is placed parallel to the transverse axis of the IR for a lateral projection of the facial bones? infraorbitomeatal
For a lateral projection of the facial bones the CR will enter the: halfway between the outer canthus and the EAM
The lateral projection clearly demonstrates the: all facial bones in their entirety
For the Waters method, the orbilomeatal line is placed at what angle to the IR? 37 degrees
Where is the CR for the parietoacanthial projection of the facial bones? acanthion
Which facial bones are clearly demonstrated in the parietoacanthial (Waters) projection? orbits, maxillae, zygomatic arches
The parietoacanthiomeatal of the facial bones is often modified so there is less angulation of the facial bones, the sorbitomeatal line is adjusted to what angle? 55 degrees
What baseline is placed perpendicular to the IR for the acanthioparietal projection of the facial bones? mentomeatal line
Trauma patents may arrive in the department with their ahead mobolized, a reverse watersd can be performed by adjusting the CR to be parallel to the: mentomeatal line
The CR angulation for the Waters method is: 0
In the parietoacanthial projection, the orbital floor should be: perpendicular to the IR and parallel to the CR
The parietoacanthial projection requires the CR to exit the: acanthion
To correct positioning for a situation where the petrous pyramids are projected in the maxillary sinuses for a parietoacanthial projection a technologist should: extend the chin
The best single projection for facial bones is: parietoacanthial (Water)
The best projection for orbital fractures is the: Modified Waters
