Understanding periorbital muscle anatomy is key for predictable aesthetic outcomes with neuromodulators. This knowledge enhances nonverbal cue perception and patient satisfaction in periorbital treatments.
Area of Science:
- Aesthetic medicine
- Facial anatomy
- Neuromodulation
Background:
- Eyebrow position conveys emotional status and nonverbal information.
- Periorbital muscles interplay to create facial expressions.
- Understanding this interplay is crucial for effective neuromodulator treatments.
Purpose of the Study:
- Summarize anatomic and clinical knowledge of periorbital muscles.
- Provide a foundation for predictable aesthetic outcomes.
- Improve physician confidence in periorbital neuromodulator treatments.
Main Methods:
- Narrative review of anatomic and clinical experience.
- Focus on glabella and forehead periorbital region.
- Analysis based on author's dissections and treatments.
Main Results:
- Description of relevant periorbital muscle anatomy.
- Analysis of muscle contributions to facial expressions.
- Simulation of neuromodulator injection effects on muscles.
Conclusions:
- Functional anatomy knowledge is essential for periorbital neuromodulation.
- Individualized assessment and planning ensure predictable outcomes.
- Aesthetically pleasing results improve perception of nonverbal cues.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
