Abstract
Background: Most cases of facial asymmetry involve yaw deformity, and determination of the yaw correction level is very difficult.
Methods: We use three-dimensional soft tissue simulation to determine the yaw correction level. This three-dimensional simulation is based on the addition of cephalometric prediction to gradual yaw correction. Optimal yaw correction is determined visually, and an intermediate splint is fabricated with computer-aided design and computer-aided manufacturing. Application of positioning devices and the performance of horseshoe osteotomy are advisable.
Results: With this procedure, accurate repositioning of jaws was confirmed and patients obtained fairly good facial contour.
Conclusions: This procedure is a promising method for a widespread, predictable treatment of facial asymmetry.
