Correction of Facial Asymmetry Using Dermal Fillers: Understanding the Role of Facial Rotation.

Facial asymmetry is a common challenge in esthetic medicine, requiring a comprehensive understanding of three-dimensional rotation patterns-X, Y, and Z axes-that significantly influence treatment outcomes. Traditional correction methods often overlook these rotational dynamics. This manuscript presents a case study of a 38-year-old Asian male patient with facial asymmetry, treated with hyaluronic acid (HA) fillers using a novel approach incorporating facial rotation concepts. By identifying the patient's clockwise facial rotation pattern and applying targeted, asymmetric filler placement, a significant improvement in facial harmony was achieved. The rheological properties of the MaiLi Extreme (Sinclair) were particularly suited for structural correction. This approach highlights the importance of rotation-based assessment and personalised treatment planning in achieving optimal esthetic outcomes.
