Anterior Auricular Muscle, Gross Anatomy

Description

Positioned on the lateral aspect of the male head, the anterior auricular muscle is shown as a small slip of striated muscle on the temporal fascia, just superior and anterior to the auricle at the root of the helix. Its fibers course inferoposteriorly toward the anterior margin of the pinna, lying superficial to the temporalis muscle and anterior to the cartilaginous external acoustic meatus. Adjacent bony landmarks of the temporal bone frame the region, with the ear canal and nearby skull contours providing attachment context. Small muscle. Clear relationships. Because the anterior auricular belongs to the extrinsic auricular musculature, this view helps clarify why voluntary pinna movement is subtle in most adults yet remains a useful surface landmark when teaching the layered anatomy of the temporal region. Surgeons and proceduralists working around the preauricular area, including approaches for parotidectomy or preauricular incisions used in temporomandibular joint exposure, benefit from a precise mental map of the auricle’s root in relation to the temporalis fascia and the external acoustic meatus. The heightened perspective also supports correlation with nerve supply, typically via temporal branches of the facial nerve, a point that matters when discussing iatrogenic weakness and postoperative asymmetry around the ear. Use this illustration in gross anatomy and head and neck dissection labs to orient learners to the extrinsic ear muscles and to anchor terminology such as auricle (pinna), helix, and external acoustic meatus in a single field. It also fits well in operative anatomy chapters and patient education materials explaining preauricular surgical approaches and scar placement.
