Three-Dimensional Analysis Techniques—Part 3: Color-Coded System for Three-Dimensional Measurement of Bone and Ratio of Soft Tissue to Bone: The Analysis

Abstract A new color-coded method of illustrating three-dimensional changes in the bone and the ratio of soft tissue to bone movement is described. The technique is illustrated by superimposing preoperative and 1-year postoperative CT scans of three patients following bimaxillary surgery. The method has proved to be a very simple, effective, and readily interpreted method of quantifying both bone and the ratio of movement of the overlying soft tissues across the face following surgery.
