An Anterior Perspective of the Superior Lip Levator Under the Skin of a Human Male

Description

Across the anterior midface, the levator labii superioris is shown as a slender, vertical facial expression muscle coursing inferiorly from the infraorbital margin of the maxilla toward the upper lip. Its fibers lie lateral to the piriform aperture and superior to the orbicularis oris, with the nasalis and adjacent perinasal mimetic musculature positioned more medially over the nasal cartilages. Deep landmarks remain visible through the translucent soft-tissue overlay, including the frontal bone, nasal bones, maxilla, and the dentition within the maxillary and mandibular alveolar processes. Inferiorly, the upper cervical vertebrae provide axial context beneath the cranial base. Clear relationships. Clinically, this muscle matters when teaching midfacial animation and planning perinasal or upper-lip procedures, because its line of pull elevates and everts the upper lip and can deepen the nasolabial groove when acting with zygomaticus minor. The illustrated proximity to the infraorbital foramen region helps frame why local anesthetic blocks, maxillofacial fracture approaches, and filler placement in the tear trough or nasolabial fold can produce transient upper-lip asymmetry if the levator labii superioris is irritated or weakened. For reconstructive work, the transparent bony reference points support accurate discussion of muscular reattachment to the maxilla after trauma. Use this anterior perspective in head and neck anatomy labs, facial expression modules for dental and medical curricula, and operative atlases covering rhinoplasty, cleft-lip repair, or midface trauma exposure where muscle planes must be respected. It also suits patient-facing education on post-procedural upper-lip movement changes when paired with basic skull landmarks and dentition.
