Resorbable osteosynthesis systems are widely used for the fixation of zygomaticomaxillary complex (ZMC) fractures instead of titanium systems, because they do not have postoperative hardware-related complications. However, the strength of conventional resorbable systems is inferior to that of titanium systems. Recently, ultrasound-aided resorbable osteosynthesis systems, which have higher fixation than conventional resorbable osteosynthesis systems, have become available.The purpose of this study was to compare the mechanical stiffness of the ultrasound-aided resorbable and titanium osteosynthesis systems in a cadaveric monoblock ZMC fracture model...

INTRODUCTION: Fractures of the zygomaticomaxillary complex (ZMC) represent an extremely heterogeneous group of injuries to the midfacial skeleton. Traditionally, the diagnosis of such fractures was based on 2-dimensional radiograms and, more recently, on volumetric computed tomography (CT) scans, while the treatment was exclusively based on the surgeon's experience. Many classification attempts have been made in the past, but no paper has taken into account the importance of virtual surgical planning (VSP) in proving a modernized classification...

The usual surgical approaches for zygomaticomaxillary complex fracture are subciliary incision, transconjunctival incision, eyebrow incision, lateral canthal incision, coronal incision, preauricular incision, and superior gingivobuccal incision. In the intraoral approach, a horizontal mucoperiosteal incision is performed at the superior gingivobuccal region, and sometimes, includes the upper labial frenum. This may cause discomfort in the oral cavity because of postoperative scarring and shortening of the upper labial frenum...

Untreated zygomaticomaxillary complex fractures may lead to aesthetical and functional sequelae needing secondary surgical correction. A 31-year-old male was addressed to our department for right enophthalmos and loss of cheek projection 3 months after facial trauma. Restauration of facial symmetry can be achieved by repositioning of the zygomaticomaxillary complex by osteotomies. To achieve good functional and aesthetical results, the reduction needs to be accurate. This is the main difficulty in delayed cases as there are less anatomical landmarks due to initial trauma and bone remodeling...

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 suture. Methods: In the retrospective study, a total of 40 patients with ZMC fracture were divided into two groups (group 1, two-point fixation and group 2, three-point fixation)...

In patients with facial trauma, multidetector computed tomography is the first-choice imaging test because it can detect and characterize even small fractures and their associated complications quickly and accurately. It has helped clinical management and surgical planning, so radiologists must communicate their findings to surgeons effectively. In Le Fort fractures, there is a breach between the pterygoid plates and the posterior maxilla. These fractures are classified in three basic patterns that can be combined and associated with various complications...
