Corrugator Supercilii as, Anterior View

Description

Centered in the glabellar region, the corrugator supercilii is indicated deep to the medial eyebrow, arising from the superomedial orbital margin of the frontal bone near the nasal process and running superolaterally into the dermis of the supercilium. From this anterior perspective, the muscle sits medial to the frontalis and superior to the orbital rim, immediately adjacent to the supratrochlear and supraorbital neurovascular corridors that exit the orbit. Surrounding bony landmarks of the skull model include the frontal bone, nasal bones, maxilla, and mandible, with the orbits framing the target area. Corrugator anatomy matters because small errors in localization translate into visible asymmetry and functional complications when treating glabellar rhytides. Injectors aim to weaken corrugator pull that draws the eyebrow medially and inferiorly, but diffusion toward the levator palpebrae superioris can produce upper eyelid ptosis, and spread toward the frontalis can lead to unwanted brow descent. This anterior mapping also helps distinguish corrugator from procerus activity at the nasal bridge, a common teaching point when planning botulinum toxin patterns. Facial anatomy courses, aesthetic medicine training decks, and dermatology or plastic surgery patient education materials often need a clean anterior reference for the corrugator supercilii and its relationship to the medial orbital rim. It also works well in anatomy lab manuals alongside skull osteology to anchor the muscle’s origin on palpable bone. Anatomical accuracy verified by SciePro's Medical Advisory Board.
