Group 5 has 6 participants who will study orbital meatal and radiographic baselines. The orbital meatal line passes through the outer corner of the eye and center of the ear canal and is used to position patients for skull x-rays like Water's view and lateral views. Radiographic baselines use consistent anatomical landmarks like the skull vault to position projections. The anthropological baseline imagines a line between the lower eye socket and top of the ear opening.

3. Orbital meatal or radiographic baseline
• Orbitomeatal line is a positioning line used in radiography of the skull. It
passes through the outer canthus of the eye and the center of the external
auditory meatus. It is used for positioning the patient for different radiographic
views including Water's view, Perorbital view, Lateral view, and others.

5. Radiographic baseline
• This are the lines that are used as the main anatomical
landmarks for positioning various projections of the skull,
sinuses, and facial bones. Both base lines maintain a constant
relationship to the cranial vault which does not vary from infancy
to adulthood.

6. Anthropological baseline
• An imaginary line that passes from the lower border of the orbit to the superior
margin of the external auditory meatus.
