tragion

Tragion is a anatomical landmark on the human skull. It is located at the inferior margin of the earlobe. More precisely, it is the most inferior point of the external auditory meatus, the opening to the ear canal. The tragion serves as a reference point in various anatomical and medical contexts, particularly in fields such as otolaryngology (ear, nose, and throat medicine) and forensic anthropology. Its consistent location makes it useful for measurements and comparisons related to the head and face. For example, in otolaryngology, the tragion can be used to help position instruments during ear examinations or surgical procedures. In forensic science, it can be employed as a fixed point for estimating the age or sex of skeletal remains, or for reconstructing facial features. The tragion is easily identifiable by palpation on a living individual.
