Advantages of a Beveled Osteotomy on the Zygomatic Arch During Reduction Malarplasty.

During a conventional reduction malarplasty procedure, a dual approach including intraoral incisions and preauricular incisions is made to reduce both the zygomatic body and arch. As the preauricular approach is performed to cut the zygomatic arch, there are several remarkable advantages that can be achieved by simply beveling the osteotomy anteriorly on the zygomatic arch. This has the benefits of enhancing bone union by the increase in cross-sectional area for bone contact, decreasing palpability on the osteotomy site, placing the osteotomy more posteriorly, preventing depression in the anterior malar region, and reducing the need for metal fixtures.
