The aim of this case report is to describe the surgical technique and outcome using internal intraoral distraction devices in LeFort II distraction with zygomatic repositioning (LF2ZR). In Apert syndrome the midface is characterized by a complex hypoplasia, with the central part being more affected than the lateral orbito-zygomatic complex. In LF2ZR, the zygomas are repositioned and internally fixated, and the central midface is further advanced through a LeFort II distraction. In previous publications, the distraction has been performed using external halo-based devices. It seems that the LF2ZR procedure can be planned and performed with adequate accuracy using virtual surgical planning tools. Knowledge about the possibility of using internal intraoral distraction devices in LF2ZR is important, as the inconspicuous placement of intraoral devices can be advantageous for some patients.

Background: This study aimed to compare palatal versus buccal protraction using plates assisted with a facemask in growing Class III patients.
Methods: Twenty growing Class III patients were randomly allocated into two main groups. In Group 1, a surgical mini-plate was bent into a semicircular shape and adapted to the patient's model to extend from the canine area on one side to the contralateral canine area.

Introduction: Reconstruction of zygomatic agenesis in Treacher-Collins syndrome (TCS) poses a significant challenge. Traditional bone grafting techniques often fail to address the complex three-dimensional (3D) anatomy and biomechanical demands. This study introduces an approach using kerfed rib grafts and titanium scaffolding for such reconstructions.

Asians often present with a prominent malar complex, resulting in a relatively flat and broad facial contour. While pronounced zygomatic projection is typically considered esthetically undesirable, conventional malar reduction procedures may not always yield satisfactory outcomes. This is largely due to the predominant focus on repositioning the zygomatic body and arch, with insufficient attention to the periorbital segment.

Background: Zygomaticomaxillary complex (ZMC) fractures are commonly treated using either local or coronal incisions, each approach having distinct advantages and disadvantages.
Purpose: The purpose of this study was to compare treatment outcomes by imaging measurements in zygomatic fractures treated with local or coronal incision surgery.
Study Design, Setting, Sample: This retrospective cohort study analyzed surgically treated ZMC fractures at the Second Hospital of Lanzhou University (2021 to 2023).

Background: The zygomaticomaxillary complex (ZMC) is essential for midface contour and width. If untreated or delayed, ZMC fractures can lead to deformities that restrict function and impair aesthetics. These deformities result from shifts in bone position and the masseter muscle's downward pull on fractured segments, causing elongation at the frontozygomatic (FZ) region and exacerbated by soft tissue fibrosis.
