zygomatico maxillary complex

Zygomatic bone fractures should be effectively diagnosed and treated because they affect how the face is shaped for both aesthetically and functional reasons. It is possible to compare different surgical techniques and their comorbidities objectively through using outcome quantitative assessments, which call for a treatment programme and long-term follow-up. The purpose of this study was to compare the outcomes of two procedures and the effectiveness of the zygomatic bone following open reduction internal fixation (ORIF) employing two-point fixation and ORIF employing three-point fixation...

A balance between surgical access and aesthetics, with lesser post-op sequelae, is inevitable in the management of facial fractures. Even though various approaches are widely practised, further modifications and revisions are encouraged for better outcomes. We performed a prospective cross-sectional study on 30 patients with Zygomatico-Maxillary Complex (ZMC) fracture with inferior orbital rim involvement. Surgical management was performed using subtarsal (Group A) or laterocaudal (Group B) approach, during which the time taken to expose fracture and the ease of access was documented...

INTRODUCTION: Contemporary incisions used to access the frontozygomatic (FZ) sutures are the lateral brow and upper blepharoplasty incisions which are associated with specific limitations and complications. The authors describe the use of sub-brow incision as an alternate approach for exposure of the FZ region. METHODS: This is a prospective cohort study involving patients requiring surgical management of zygomatico maxillary complex (ZMC) fractures with fixation at FZ suture alone or along with fixation at infra-orbital rim and/or zygomaticomaxillary buttress...

Patients of all age groups diagnosed with unilateral displaced zygomatic complex fracture with or without mandible fracture were included in the study...

Congenital fusion of the jaws (syngnathia) is a rare facial malformation with an unknown etiology. This disease may vary in severity with adhesion of soft tissue and bony fusion. It can be anterior fusion, unilateral or bilateral fusion, and complete fusion. The main problem of these patients is the difficulty of airway maintenance and feeding, and the most common postoperative complication is the relapse of bony fusion. Here, we report a young male patient with bony syngnathia, involving bilateral fusion of the ascending ramus and body of the mandible with the maxillary complex...

OBJECTIVE: To develop a reliable and accurate method to quantify the symmetry of the zygomaticomaxillary complex (ZMC). METHODS: Virtual three-dimensional models were created from 53 computed-tomography scans: 15 healthy cases without maxillofacial disorders and 38 patients with ZMC fractures requiring surgical treatment.Asymmetry of the ZMC was measured using a mirroring and surface-based matching technique that uses the anterior cranial fossa as reference to determine the symmetrical position of the ZMC...

INTRODUCTION: Coronoid fractures are relatively rare fractures of the craniofacial skeleton, but typically occur concomitantly with high-velocity craniofacial trauma to the midface and lateral mandible. Management of coronoid fractures may vary, but when surgical excision is indicated, treatment frequently involves an intraoral approach through a posterior intraoral incision along the mandibular ramus. Here, the authors present an alternative and novel approach to the coronoid process based on the Keen approach to the lateral midface...

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...
