What is the average angular difference between the orbitomeatal and infraorbitomeatal lines in adults?

The average angular difference between the orbitomeatal and infraorbitomeatal lines in adults is approximately 7 to 8 degrees. This measurement is significant in radiological practice, particularly in positioning and interpreting cranial images. Understanding this angular relationship helps radiologists and healthcare professionals align imaging planes correctly, which is critical for accurate diagnosis and evaluation of facial and cranial anatomy. The orbitomeatal line is defined by the plane that runs horizontally from the outer canthus of the eye to the midpoint of the orbit, while the infraorbitomeatal line connects the infraorbital rim to the midpoint of the external auditory meatus. Recognizing this angular variance allows for improved consistency and accuracy in imaging assessment and planning treatments in a clinical setting.
