The current study was designed to: (1) compare the sensitivity of a 2-dimensional video-based system with a 3-dimensional optical system, and (2) investigate movement on the affected and unaffected side of the face during the production of various functional movement tasks in 5 patients who had undergone facial reanimation surgery. The study showed that: (1) distance is the most valuable measure for evaluating facial paralysis, regardless of system; (2) movements associated with maximal contraction and running speech tasks are most informative when assessing facial paralysis; (3) area and volume ratios may be an appropriate measure for tracking changes in facial movement over time; (4) velocity and acceleration measures provide minimal information regarding facial movement; and (5) 2-dimensional analysis is most effective when distance is measured during maximal contraction and running speech tasks. Both systems were effective in tracking small movements of the face, but the 3-dimensional system was superior overall.
