Occlusion-Fit Three-Dimensional–Printed Zygoma Repositioner

Reduction malarplasty is utilized to reshape the facial form into an oval shape. However, complications and unfavorable results in reduction malarplasty have been reported. Reoperation of a nonunion malar complex is difficult relative to the achievement of a satisfactory outcome using the intraoral approach with a narrow surgical field because the normal anatomy has been destroyed, and previous surgery may have caused asymmetry. In this situation, computer-aided simulation surgery and surgical guides can serve as effective solutions to overcome the limitations of reoperative malarplasty using the intraoral approach. In this report, the authors present a case with successful treatment outcomes for a nonunion malar complex using a three-dimensional-printed zygoma repositioner.
