Abstract

Several visual assessment methods have been proposed for evaluating facial nerve function. They are of value clinically, but they have drawbacks when objective, quantitative, and reproducible assessment is required. To solve these problems, we used moire topography, which helps visualize information in three dimensions. We previously reported that one could evaluate the severity of facial palsy by observing characteristic patterns of the moire strips produced by facial movement. Accordingly, we developed a new form of the dynamic evaluation by recording the dynamic changes in moire strip patterns on the face on a videotape.
