Evaluating symmetry and facial motion using 3D videography.

Advances in 3-dimensional (3D) data capture, tracking, and computer modeling now allow for more appropriate measurement and analysis of the face. 3D video not only enables precise analysis of facial symmetry, it broadens our capabilities to accurately study facial volume and facial movement and the forces generated within tissue. Research in facial plastics outcomes has traditionally been evaluated with subjective measures. Current 3D methods are far superior and generate reproducible, accurate, and objective data for such clinical studies. As these technologies become more readily available, there will be a paradigm shift in how aesthetics research is conducted. 3D videography and newer technologies on the horizon will not only change current research methods; they will be much more pervasive in the clinical practice of aesthetic surgeons as they are incorporated into preoperative planning and used to improve patient communication.
