BACKGROUND: Infraorbital nerve dysfunction is commonly reported after zygomaticomaxillary complex fractures. We evaluated sensory changes in four designated areas (eyelid, nose, zygoma, and lip) innervated by the infraorbital nerve. This evaluation was conducted using the static two-point discrimination test and the vibration threshold test. We assessed the diagnostic significance of the blink reflex in patients with infraorbital nerve dysfunction. METHODS: This study included 18 patients, all of whom complained of some degree of infraorbital nerve dysfunction preoperatively...

Orthognathic surgeries often utilize rigid fixation for stabilization of the osteotomy site. The longterm fate of rigid fixations is still under investigation, and whether they should be routinely removed is under debate despite their low complication rates. Here, we report a case where a 26-year-old man suffered high-velocity trauma to his face 7 years after a two-jaw surgery. Computed tomography examination revealed a zygomaticomaxillary complex fracture, and open reduction and internal fixation was performed along with anterior maxillary wall reconstruction using absorbable mesh...

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...

Open reduction followed by internal fixation (ORIF) has been regarded as the most effective technique for surgical repair of zygomaticomaxillary complex (ZMC) fractures. However, the ideal internal fixation method to achieve stable reduction remains controversial. This research aims to assess and compare the stability of the 2- and 3-point screw-plate fixation methods using finite element method (FEM). Based on computed tomography (CT), the finite element models of 2-point (ZFS + IOR) and 3-point (ZFS + IOR + ZMB) fixation for isolated displaced ZMC fracture were reconstructed...

In this unique case report, we present a patient of left zygomatico maxillary complex reconstruction with a combination of autogenous tissue (osteocutaneous free fibula flap) and alloplastic implant [patient-specific templated polymethyl methacrylate (PMMA)]. In such large defects, reconstruction using either autogenous tissue or alloplastic implant alone is inadequate and leads to poor functional and aesthetic outcomes. In this case we used osteocutaneous free fibula flap for left alveolus and patient-specific templated PMMA implant for reconstruction of orbital wall and zygoma...

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...
