Pertinent anatomy and analysis for midface volumizing procedures.

Area of Science:

• Anatomy
• Aesthetics
• Facial Rejuvenation

Background:

• Nonsurgical midfacial rejuvenation requires precise anatomical understanding.
• Current techniques lack standardized, anatomically derived guidelines for safe and effective injections.

Purpose of the Study:

• To create an anatomically inspired midfacial analysis for safe and accurate nonsurgical rejuvenation.
• To define specific injection target areas and identify zones associated with adverse events.

Main Methods:

• Dissection of twelve fresh hemifacial cadavers.
• Layered dissection to measure distances between midfacial fat compartments, prezygomatic space, mimetic muscles, and neurovascular bundles.
• Development of a topographic analysis for clinical injection guidance.

Main Results:

• A longitudinal line partitions the cheek into aesthetic regions, aiding in defining injection points.
• A six-step analysis identifies three target zones and two adverse event zones.
• Specific anatomical landmarks correlate with potential complications like jowling and infraorbital artery injury.

Conclusions:

• The developed stepwise analysis provides a reproducible method for identifying midfacial target and adverse event zones.
• This approach enhances safety and accuracy in nonsurgical midface volumizing procedures.
• The method supports both procedural application and record-keeping for consistent outcomes.
