Tragicus Muscle Under the Skin, Lateral View

Description

Situated on the lateral surface of the male auricle, the tragicus muscle is shown as short, vertically oriented intrinsic fibers embedded in the tragal cartilage, just anterior to the external acoustic meatus. The tragus forms the anterior boundary of the conchal bowl, and the tragicus lies superficial to the cartilage but deep to the thin, hair-bearing skin of the preauricular region. Superior and posterior to this focus, the helix and antihelix contour the lateral pinna, while the lateral cheek and temporal fossa frame the auricle in profile. A narrow segment of the cartilaginous ear canal is partially visible deep to the tragus. For teaching, the tragicus is easy to overlook because it is small and often variably developed, yet it anchors the concept of intrinsic auricular muscles as distinct from the extrinsic auricular muscles that move the pinna. This lateral perspective also supports preauricular surgical planning, since incisions and dissection planes used for approaches to the temporomandibular joint, parotid region, or external ear reconstruction must respect the thin subcutaneous layer overlying auricular cartilage to avoid contour deformity, chondritis, or conspicuous scarring at the tragus and intertragic notch. Small anatomy matters here. Useful for head and neck anatomy courses, otolaryngology teaching files, and operative atlases discussing auricular landmarks for otoplasty, tragal cartilage graft harvest, or periauricular incisions in rhytidectomy and parotidectomy. It also fits patient-facing education where the tragus and ear canal entrance need clear orientation without distracting deep anatomy. Anatomical accuracy verified by SciePro's Medical Advisory Board.
