Abstract
Zygoma reduction is indicated in patients where the primary aim of surgery is reduction
in the width of cheekbones to achieve smoother and more feminine facial aesthetic
lines. Surgeons should evaluate the width of midface (bizygomatic width) and the protrusion
of zygoma (volume and position of the zygomatic body) when evaluating patients where
such a procedure is indicated. Intraoral high-L osteotomy is the most useful method
to successfully treat a wide spectrum of zygomatic protrusions and is widely accepted
as the treatment of choice for aesthetic purposes. The amount of ostectomy is determined
by evaluating the volume of zygomatic body. The zygomatic body and arch are usually
moved posteromedially during surgery; the point of maximal malar projection is evaluated
and transposed to a new ideal position. Zygoma reduction can be performed solely or
in combination with other facial bone contouring procedures such as mandible reduction,
genioplasty, or forehead augmentation. Soft tissue sagging, nonunion, malunion, and
paresthesia are the most common complications of this procedure. Undercorrection and
asymmetry are the most common aesthetically unfavorable sequelae and should be carefully
prevented by proper preoperative planning and meticulous execution of surgical technique.
