Abstract
Secondary deformities of the zygoma are a rare entity, thanks to the adoption and
refinement of open reduction and internal fixation techniques. These injuries are
often difficult to treat due to the unique structural, functional, and aesthetic properties
of the zygoma. Purely cosmetic defects can often be managed with implants; however,
functional deficits generally require mobilization, correction, and subsequent fixation
of the defect(s). Performing the necessary osteotomies to mobilize the zygoma is the
most crucial part of the procedure, and had traditionally been executed without the
use of computer aids. Planning for and performing this step was very difficult and
frequently resulted in unsatisfactory outcomes. Recent advancements in virtual mapping
and planning have obviated the need for guesswork and have resulted in improved functional
and aesthetic outcomes following repositioning. This article will discuss the use
of implants, osteotomies, and computer-assisted design/modeling (CAD/CAM) in addressing
secondary deformities of the zygoma.
