Lateral Perspective of the Auricular Cartilage Beneath the Dermal Layer

Description

Seen in left lateral profile, the male auricle is presented with the dermal layer reflected to expose the underlying auricular cartilage and its relief, including the helix and antihelix, scapha, triangular fossa, concha (cymba and cavum), tragus, antitragus, and the lobule inferiorly where cartilage is absent. Posteriorly and superiorly, the cartilage lies against the mastoid region and temporal scalp, while anteriorly it frames the external acoustic meatus in the tympanic part of the temporal bone. Adjacent facial structures in the same plane include the temporalis over the temporal fossa and the masseter over the ramus of the mandible, with portions of the maxilla and mandible providing osseous context beneath the superficial soft tissues. Subtle. Cartilage sits just deep to the skin. A lateral dissection-style view of auricular cartilage matters because the auricle’s folds are the landmarks clinicians use to orient laceration repair, local anesthesia, and perichondrial elevation. Hematoma in the potential space between perichondrium and cartilage, classically after blunt trauma, can devascularize cartilage and lead to cauliflower ear if not promptly drained and compressed. Otoplasty and auricular reconstruction also rely on appreciating where cartilage is rigid (helix, antihelix, concha) versus where soft tissue predominates (lobule), and on maintaining skin-perichondrium integrity to avoid contour irregularities. Use this artwork in head and neck anatomy teaching when introducing the external ear, the tympanic part of the temporal bone, and surface anatomy of the external acoustic meatus, or in ENT and plastic surgery materials covering auricular hematoma management, otoplasty planning, and post-traumatic ear repair. It also supports patient-facing explanations of why cartilage injuries behave differently from skin-only lacerations. Anatomical accuracy verified by SciePro's Medical Advisory Board.
