Minor Helical Muscle, Lateral View

Description

Positioned on the lateral surface of the auricle (pinna), the minor helical muscle (musculus helicis minor) lies superficial to the auricular cartilage along the anterior limb of the helix, immediately adjacent to the crus helicis as it projects into the conchal bowl. From this profile perspective, the helical rim curves superiorly and posteriorly, while the crus of the helix sits more anterior and medial, bridging toward the concha. Subtle relief of the scapha and antihelix typically frames the region posteriorly. Small structure, specific landmark. For otologic teaching, this view matters because the intrinsic auricular muscles are easy to confuse with the extrinsic auricular muscles and with cartilaginous folds when learners first encounter the auricle in dissection or surface anatomy. The helicis minor is a consistent reference point along the helical root, a region traversed in common procedures such as auricular hematoma drainage and repair, helical rim laceration closure, and cartilage-sparing incisions in otoplasty, where staying in the correct plane superficial to perichondrium helps reduce chondritis and contour deformity. Its relationship to the crus helicis also supports accurate description of congenital variants around the helical root and conchal rim. Use this illustration in head and neck anatomy courses to differentiate intrinsic auricular musculature from the cartilaginous framework, and in surgical education materials covering otoplasty landmarks, auricular trauma repair, and perichondrial planes. It also fits well in dermatology and procedural guides for helical and conchal lesion excision where precise surface mapping on the male auricle is required.
