Complementary Strategies for Temporal Lifting Techniques: Biomechanical Insights From Combined Injection Techniques

Area of Science:

• Aesthetic Medicine
• Dermatology
• Plastic Surgery

Background:

• Hyaluronic acid fillers in the lateral face provide full-face aesthetic benefits.
• Limited systematic comparisons exist for different soft tissue filler injection techniques.

Purpose of the Study:

• To compare full-face aesthetic effects of posterotemporal lifting alone versus combined with supraperiosteal zygomatic arch injection.
• To evaluate aesthetic assessment using images from three device types.

Main Methods:

• Retrospective analysis of 20 female Asian patients divided into two groups.
• Group A: Subcutaneous posterosuperior temporal injections. Group B: Additionally received supraperiosteal zygomatic arch injections.
• Outcomes assessed via Global Aesthetic Improvement Scale (GAIS) and 3D volume/vector change quantification.

Main Results:

• Group B showed greater vector displacement in the inferolateral and medial face.
• GAIS scores favored the combined approach (Group B) over simple temporal lifting (Group A).
• Three-dimensional (3D) imaging provided superior aesthetic assessment compared to two-dimensional (2D) imaging.

Conclusions:

• Combined temporal lifting with supraperiosteal zygomatic arch injection yields enhanced facial lifting effects.
• This combination is more effective than simple temporal lifting using equivalent filler volumes.
