Application of Computer Techniques in Correcting Mild Zygomatic Assymetry With Unilateral Reduction Malarplasty

Zygomatic assymetry is common in the population, which often requires surgical correction for aesthetic concerns. Previously, surgeons performed the surgery often based on their personal experience and visual evaluation. The purpose of this study was to apply computer techniques in patients with mild zygomatic asymmetry treated with unilateral reduction malarplasty to improve surgical accuracy and reduce preoperative risks. The authors used computer techniques to plan osteotomies, to produce surgical template, and to evaluate the surgical outcome. Postoperative follow-up demonstrated that zygomatic asymmetry was corrected in all the patients without complications. The proposed methodology was considered to be helpful in improving the surgical accuracy and efficiency for treatment of zygomatic asymmetry, while greatly minimizing operative risk.
