#auricular

• Antehelix — A curved prominence of the external ear pinna, situated in front of and parallel to the helix, separated from it by the scaphoid fossa. This cartilaginous structure bifurcates in its upper part into two flexible crura that frame the triangular fossa, playing an essential role in capturing, reflecting, and guiding sound waves toward the external auditory canal.
• Antitragus — A small, cartilaginous prominence located on the pinna of the external ear (auricle), situated symmetrically at the lower part of the antihelix and placed directly opposite the tragus, from which it is separated by the intertragic notch. This fine anatomical structure plays a decorative and functional role in helping direct sound waves into the external auditory canal and also represents a common landmark in modern piercing procedures.
• Antromastoiditis — An acute or chronic bacterial inflammatory and infectious condition affecting simultaneously the mucosa and bony structure of the mastoid antrum and the neighboring mastoid cells. It usually represents a severe complication of suppurative otitis media, clinically characterized by intense retroauricular pain, high fever, local erythema, and purulent discharge, requiring aggressive antibiotic treatment or surgical drainage.
• Auricular — Pertaining to the ear or the cardiac auricle; auditory. As a masculine noun, it designates the pinky finger (named so because its size fits the external auditory canal). In linguistics and historical theology, it describes a confession made directly into someone's ear (e.g., auricular confession).
• Wood ear — A genus of basidiomycete fungi within the family Auriculariaceae, characterized by gelatinous, lobed fruiting bodies whose shape resembles the human ear pinna (such as Auricularia auricula-judae, popularly known as Judas's ear or wood ear, widely used in Asian cuisine).
