Standard Terminology for the Ear

The appearance of facial morphology varies considerably with the position of the observer and observed person, and facial movements. In assessing morphology, the head of the observed person should be held in the Frankfurt horizontal, with the facial and neck muscles relaxed, eyes open, lips making gentle contact, and a neutral facial expression. The face of the observer should be at the same height as the face of the observed person. A detailed description of the anatomic features of the ear is available for reference.

The definitions are listed alphabetically based on the physical feature, not the modifier.
