Zygomaticus Minor Under the Skin

Description

Presented in lateral profile of an adult male head and upper neck, the zygomaticus minor is isolated beneath the skin as it descends from the zygomatic bone along the superolateral cheek toward the upper lip. Deep and posterior to it, the masseter occupies the lateral surface of the mandibular ramus, while the maxilla and mandible frame the dentition anteriorly and inferiorly. Superiorly, the nasal cartilages and anterior nasal aperture border the midface, and inferiorly the upper cervical vertebrae align posterior to the pharyngeal region. Zygomaticus minor is a key elevator of the upper lip, shaping the nasolabial fold and contributing to expressions that clinicians often assess in facial nerve (CN VII) dysfunction. Small but diagnostic. In aesthetic and reconstructive planning, this muscle lies in the field of midface approaches (including sublabial and transcutaneous dissection planes) and its relationship to adjacent mimetic musculature helps explain asymmetry after trauma, parotid surgery, or iatrogenic nerve injury. Use this artwork in head and neck anatomy teaching to differentiate the zygomaticus minor from the zygomaticus major and levator labii superioris by line of pull and insertion, and in clinical communication pieces discussing facial reanimation, Bell palsy grading, or smile analysis in orthodontics and maxillofacial surgery. It also suits atlases and patient-facing surgical consent materials that require a clean profile view integrating skull landmarks, teeth, and cervical alignment.
