Question

The parietoacanthial projection (Waters method) of the facial bones is often modified so that there is less angulation of the facial bones. For this modification, the orbitomeatal line is adjusted to _____ degrees.

a) 30 degrees
b) 37 degrees
c) 55 degrees
d) 60 degrees

Answer 1

c) 55 degrees

Step-by-step explanation:

This inclination is also done so there is less inclination and extension of the neck since the patient ends up with the OML (orbitomeatal line) more perpendicular to the IR plane.
