Skull base and face

The neuro-ocular plane (N.O.P.) remains the most accurate cephalic orientation for the investigation and biometrical study as well as for follow-up of diseases of the eyes and the optic nerves in the axial or in the coronal planes. The same applies to the screening and exploration of diseases involving the face and skull base, due to the close parallelism of NOP to the Frankfurt-Virchow anthropological baseline. Several works demonstrated these widely adopted results.
