On the sinuses, PA no angle, would place the petrous ridge filling out the orbits? do we want them to be at 1/3 in the lower portion of the orbits for sinuses? if so, tucking in the chin to make up for the straight shot would place the ridges at 1/3? I'm little confused, please advise, thank you.
The lack of angle accommodates for the ones we do for the skull, you an image of the sinuses was done with the head tilted or an angle on the tube you would not see true fluid levels. Think of a bottle of water if you're looking at it straight on you can see the true fluid level. If you tilt it, it looks like there is more than there truly is make sense? Hope that helps!
Also if it helps more between the Caldwell and the sinus Caldwell it's a 15* difference which is what changes where they live due to tuck/tilt of the head
