Zygomaticomaxillary fractures account for approximately 25% of all facial fractures. They can be grouped into high-velocity and low-velocity injuries. A complete head and neck examination is critical for accurate clinical diagnosis. A thin-cut axial CT scan with sagittal, coronal, and 3-D reconstruction is important for accurate diagnosis and treatment planning. A thorough understanding of bony tetrapod anatomy and fracture mechanics is critical to treatment planning. Treatment options include closed and open reduction with internal fixation...

BACKGROUND: Zygoma is a major buttress of the midfacial skeleton, which is frequently injured because of its prominent location. Zygoma fractures are classified according to Knight and North based on the direction of anatomic displacement and the pattern created by the fracture. In zygomaticomaxillary complex (ZMC) fracture many incisions (lateral eyebrow, lateral upper blepharoplasty, transconjunctival, subciliary, subtarsal, intraoral, direct percutaneous approach) are useful. We reviewed various approaches for the treatment of ZMC fractures and discussed about incisions and fixation methods...

PURPOSE: Reduction malarplasty is one of the most common esthetic surgical procedures performed in the Asian population. Traditional procedures have several complications, such as bone nonunion, malunion, cheek drooping, and damage to the infraorbital nerve and maxillary sinus. Therefore, a more straightforward and effective method of reducing the width of the midface is needed. In this study, we introduce an infracture technique using inward displacement of the zygomatic arch without fixation...

A novel surgical treatment sequence for secondary orbitozygomatic complex (OZC) reconstruction is described. Orbital reconstruction is performed before OZC repositioning. A surgical plan is made: the affected OZC is virtually osteotomized and aligned with a mirrored model of the unaffected OZC. A patient-specific implant (PSI) is designed for orbital reconstruction. Screw holes from the primary reconstruction are used for fixation. Primary screw hole positions at the repositioned OZC are embedded in the design, to guide OZC repositioning...

Zygomaticomaxillary complex (ZMC) fracture is a common type of maxillofacial fracture. In addition to facial depression and diplopia, paresthesia of the lower eyelid, malar regions, nose skin, upper lip skin, and mucous membranes occurs because of infraorbital nerve injury. This article reviewed the anatomy, diagnosis, assessment, treatment, and prognosis of ZMC fracture-related infraorbital nerve injury.

INTRODUCTION: Although some studies addressed the differences between subciliary and transconjunctival approaches, no previous prospective comparative study on displaced zygomaticomaxillary complex (ZMC) fracture that repaired by three-point internal fixation using also upper gingivolabial incision and upper eye lid incision. So, the effect of these incisions on the comparison was not investigated. PURPOSE: The purpose of this study was to compare transconjunctival and subciliary approaches for open reduction and internal rigid fixation (OR/IF) of ZMC fractures...

The aim of this study was to analyze the use of C-arm and its significance in accurate reduction of zygomaticomaxillary complex (ZMC) fractures. Orbital volume is used as parameter to compared pre- and postoperative volumes of injured orbit. Differences in orbital volume calculated in cases done with intraoperative imaging and in controls treated without the use of intraoperative imaging were evaluated using Student t-test. C-arm is definitively an effective tool in the armamentarium of oral and maxillofacial surgery in assessment of reduction of ZMC fracture...

Blow-in fracture of the zygomaticomaxillary complex that was displaced into the orbital cavity could be associated with ophthalmologic injuries, ranging from visual acuity to ocular motility limitation. Appropriate reduction and realignment of the fractured bone is necessary as early as possible for recovery of function and esthetics. However, limitation of accessibility and visibility makes it difficult for delicate surgery and increases the risk of damage of adjacent anatomic structures, such as optic nerve and extraocular muscles...

INTRODUCTION: The zygomaticomaxillary complex is very vulnerable to injury because of its intrinsically prominent convexity. There are 2 different surgical approaches for the therapy of these fractures: closed reduction and open reduction. In the open reduction 2 or 3 fixation points with related incisions are usually necessary in dislocated fractures: osteosynthesis must be performed starting from zygomaticofrontal suture when dislocated at this site, followed by zygomatic body fixation on the anterior sinus wall, anterior orbital floor margin fixation, and finally orbital floor reconstruction in case of eye globe dislocation with diplopia...
