Repair of facial trauma such as that sustained during a high-speed motor vehicle accident, as described in this patient report, can be functionally and esthetically challenging. Here, successful postsurgical management of wound breakdown following a zygomaticomaxillary complex fracture repair included use of a self-adhesive hydrogel wound dressing . However, the effect on restoration of facial symmetry and fracture reduction is yet to be established
The procedure should be considered for patients with unilateral or bilateral displacement of the zygomaticomaxillary complex with malar flattening, trismus, canthal dystopia, diplopia, globe malposition, or enophthalmos. Surgical treatment should be completed within 2 weeks from the time of injury Zygomaticomaxillary complex (ZMC) fractures are a group of fractures that can significantly alter the structure, function, and appearance of the midface, including the globe. Like other facial fractures, the optimal management of operative ZMC fractures requires anatomic reduction of all fractures followed by rigid internal fixation . Hollier LH Jr(1).

Patients with a nondisplaced or minimally displaced zygomaticomaxillary complex (ZMC) fracture and normal findings on ophthalmologic examination can be treated conservatively. Medical management.. Zygomaticomaxillary complex (ZMC) fractures , also known as tripod, tetrapod, quadripod, malar or trimalar fractures, are seen in the setting of traumatic injury to the face. They comprise fractures of the: zygomatic arch. inferior orbital rim, and anterior and posterior maxillary sinus walls. lateral orbital rim The zygomaticomaxillary complex (ZMC) plays a key role in the structure, function, and aesthetic appearance of the facial skeleton. It provides normal cheek contour and separates the orbital.. A zygomaticomaxillary complex (ZMC) fracture is a fracture that involves the zygoma and its surrounding bones. They are the second most common facial fractures after nasal bones. This article details the anatomy, evaluation, and treatment Successful repair of ZMC fractures requires an accurate diagnosis, appropriate surgical exposure, and precise reduction to reconstitute the complex 3-dimensional anatomy. Axial CT scan demonstrating zygomaticomaxillary complex fracture on right with severe displacement
The physician makes facial incisions through the scalp, eyebrow, and/or lower eyelid. A transoral incision is also made through the maxillary buccal vestibule. The fracture sites are exposed. Instruments may be inserted into the bone (e.g., Carroll-Girard screw) or beneath the complex to lift the fracture Introduction. Zygomatic complex (ZMC) fractures are relatively common. A literature search showed ZMC fractures to account for approximately 15%-23.5% of maxillofacial fractures [1-3].The incidence of ZMC fractures varies with geographical location, socioeconomic trends, and incidence of road traffic collisions (RTCs), alcohol abuse and drug abuse .A number of studies had shown ZMC fractures. Zygomaticomaxillary Complex (ZMC) fractures result from blunt trauma to the periorbital area (viz. malar eminence). ZMC fractures are also referred to as tripod, trimalar, tetrapod, quadripod, or malar fractures. Etiologies reported in the literature include high-risk activities, such as road traffic accidents, civilian warfare, assaults or. Order of reduction and fixation. In a fracture of this nature, the reduction and fixation of the zygoma, including the zygomatic arch, orbital rim, and zygomaticomaxillary buttress should be performed first. Reconstruction of the orbital floor should be performed after the zygoma has been reduced and fixated
The zygomaticomaxillary complex fracture, also known as a quadripod fracture, quadramalar fracture, and formerly referred to as a tripod fracture or trimalar fracture, has four components: the lateral orbital wall (at either the zygomaticofrontal suture superiorly along the wall or zygomaticosphenoid suture inferiorly The zygomatic bone is a critical component of the midfacial complex. Its prominence within the face makes it susceptible to trauma and its intricate anatomy make posttraumatic repair of zygomaticomaxillary complex (ZMC) fractures challenging. The zygoma has a tetrapod structure with four key articulation points: the zygomaticomaxillary articulation and inferior orbital rim. Purpose: To present the treatment of zygomaticomaxillary complex (ZMC) fractures with closed-reduction Steinmann-pin fixation and to compare it to the reduction and aesthetic outcomes of open-reduction techniques (ORIF). Materials and Methods: Case series. Charts for 23 patients with ZMC fractures presenting to the Head and Neck Surgery Department at Harbor-UCLA Medical Center from 2005 to. The ZMC fracture is the second most common facial fracture, after the nasal bones.1 The prominent nature of the malar eminence places this structure at great risk for fracture, and the intricate 3-dimensional (3D) nature of the ZMC can sometimes make the repair quite chal
Zygomaticomaxillary Complex Fracture as an Orbital Wall Fracture A B S T R A C T. Zygomaticomaxillary complex (ZMC) fracture is common and refers to the osseous disruption of the malar eminence at its 4 buttresses: frontozygomatic, zygomaticomaxillary, zygomaticosphenoid, and zygomaticotemporal. So, ZMC fracture is considered orbital wall fracture Fractures that involve the zygoma often occur at these four [Figure 1] suture sites, leading to a tetrapod fracture pattern, known as a zygomatic complex fracture (ZMC). Furthermore, the zygoma is connected to the maxilla and sphenoid bone as part of the inferior orbital floor, and forms the lateral orbital margin with the frontal bone A plate that is placed for the fixation of the fracture at the zygomaticomaxillary buttress is generally a larger plate because it is the point that will provide most stability to the Le Fort I fracture. The highest forces of mastication would be in this area. Depending on the fracture pattern an L-, T-, Y-plate or a straight plate may be used
Zygomatic bone has a higher risk of sustaining injuries in the maxillofacial skeleton. On fracturing, zygomatic bone separates from the four neighbouring bones at its articulations. Treatment for zygomaticomaxillary fractures has evolved a long way since 3000 BC. With the advent of miniplates for midface fracture, controversies still exist regarding the stability of zygoma following 1, 2, and. In the case of comminuted fractures of the arch, one can simply slide the previously placed bone hook under the fractured arch segments and reduce them in a closed fashion. As a consequence of our hands-off approach to the zygomatic arch, we rarely, if ever, use a coronal incision for a zygomaticomaxillary complex fracture. Figure 4 Fractures of the Zygomaticomaxillary Complex Jason H. Kim INTRODUCTION Zygomaticomaxillary complex (ZMC) fractures occur frequently, representing the first or second most common facial fracture, depending on the series reported. They are challenging fractures to manage because they may affect the appearance of the face and compromise orbital and/or masticatory function

Proper and timely management of these fractures can reduce the rate of late complications. In this paper, we review the current literature regarding ZMC fracture treatment and discuss our experience from surgical treatment of multiple ZMC. Purpose . To reconstruct a zygomaticomaxillary complex (ZMC) fracture, zygomaticofrontal (ZF) suture is the most reliable site to assess anatomical alignment and to secure rigidity. It has been chosen primary site to be fixed, but approach through the lateral eyebrow incision may leave a visible scar. This study suggests altered two-point fixation of ZMC fracture without accessing the ZF.
Despite the prevalence of zygomaticomaxillary complex (ZMC) fractures, there is no consensus regarding the best approach to management. The aim of this study is to determine differences in ZMC fracture treatment among various surgical specialties Zygomaticomaxillary Complex Fractures • Zygomaticomaxillary complex (ZMC) fractures are very rare in children, especially those younger than 5 years of age. • However, the incidence of these fractures increases with the development of the maxillary sinuses Fractures of the zygomaticomaxillary complex (ZMC), orbital rim, medial orbital wall, and orbital floor are most commonly encountered. Fractures of the superior orbit occur less frequently and are often associated with frontal sinus fractures and intracranial involvement Zygomaticomaxillary complex (ZMC) fractures, also known as a tripod, tetrapod, quadripod, malar or thoracolumbar spinal fracture classification systems.
