supraaurale

The term supraaurale (plural supraaurales) refers to an anatomical region or structure situated directly above the auricle, the external portion of the ear. The word derives from Latin: “supra” meaning “above” and “aurale” pertaining to the ear (auris). In human anatomy the supraaural area includes skin, subcutaneous tissue, and the temporal fascia that overlay the temporomandibular joint and the posterior branch of the superficial temporal artery. It is bounded inferiorly by the lower margin of the auricle and superiorly by the temporal line of the skull.

Clinically, the supraaural region is significant in several procedures. Local anesthetic infiltration for ear surgery often targets the supraaural space to block the auriculotemporal nerve, thereby reducing postoperative pain. Cosmetic interventions such as filler injections and scar revision may also involve the supraaural tissue. Pathologies that may affect this area include cellulitis, temporal arteritis, and soft‑tissue tumors such as lipomas or dermatofibromas.

In comparative anatomy, many mammals possess a distinct supraaural fold or ridge that assists in directing sound towards the ear canal. Certain primates exhibit a pronounced supraaural groove that supports facial musculature. In veterinary medicine, the term supraaurale is sometimes used to describe a skin fold above the ear in breeds such as the Shar‑Pei, where it can be a site of dermatitis.

The supraaural region is also a landmark in forensic anthropology; measurements taken from the lower auricular edge to the hairline can aid in the estimation of cranial dimensions and age‑related changes. Overall, the supraaurale area, while modest in size, holds relevance across anatomy, clinical practice, and comparative biology.
