What is the name of the imaginary line drawn between the outer canthus of the eye and the external auditory meatus (EAM)?

The imaginary line drawn between the outer canthus of the eye and the external auditory meatus (EAM) is referred to as the orbitomeatal line. This anatomical landmark is significant in radiography and imaging, particularly for positioning the patient correctly during procedures such as skull radiography. The orbitomeatal line helps align the imaging plane with the anatomical structures, ensuring that the facial and cranial relationships are accurately represented in the images.

In general, understanding the orbitomeatal line is crucial for obtaining optimal images, as using this reference point can help in achieving the correct angling of the X-ray beam, thus minimizing distortion.
