Placed on the upper of the two rims
Left and right orbits rarely superimpose exactly. Taking whichever curve is clearest rather than averaging tilts Frankfort.
Point · Or
Orbitale (Or)
The lowest point of the bony orbital rim — half of Frankfort, and the easier half.
At Beginner a placement counts as found within 3.0 mm of the reviewed reading.
How to find it
Press a step to be shown it on the ceph.
Common errors
Each figure is the reviewed reading of Orbitale (Or) and a typical miss, on the same ceph, at the distance the mistake usually goes.
Slid back along the rim
The inferior rim is nearly flat for several millimeters, so there is no notch to stop the point sliding posteriorly.
Used in
10 measurements are built on it. Miss it, and every one of them moves.
