An Anterior View of the Zygomaticus Minor Muscle of a Male

Description

Arising from the lateral surface of the zygomatic bone, the zygomaticus minor runs inferomedially toward the upper lip, lying superior and slightly medial to the thicker zygomaticus major as both cross the anterior cheek. The muscle sits superficial to the maxilla and lateral to the nasolabial fold, with its fibers blending near the orbicularis oris and the upper lip elevator complex. A short muscle. Clear relationships. Because small slips of the zygomaticus minor interdigitate with levator labii superioris and orbicularis oris, this anterior facial view helps clarify why upper lip elevation and exposure of the maxillary teeth can vary between individuals, and why selective weakness changes expression patterns. Clinically, the course and depth of this cheek musculature matters during cosmetic chemodenervation and filler placement in the midface, where asymmetry can follow diffusion into adjacent mimetic muscles or inadvertent injury to the zygomatic and buccal branches of the facial nerve in the superficial musculoaponeurotic system (SMAS) plane. It also supports teaching the functional anatomy behind the nasolabial crease and smile mechanics. Use this asset for head and neck anatomy coursework, plastic surgery and dermatology teaching files, and medical publisher diagrams explaining facial expression musculature in an adult male. It also fits patient education materials for botulinum toxin injection planning around the upper lip and cheek. Anatomical accuracy verified by SciePro's Medical Advisory Board.
