Zygomaticomaxillary complex

PURPOSE: This study aimed to assess the quality of life (QOL), before and after surgery, of patients who underwent open reduction and internal fixation for orbital fractures. STUDY DESIGN: A prospective study PARTICIPANTS AND SETTING: The self-report outcome measures of 50 patients treated at the Department of Oral and Maxillofacial Surgery of the Second Affiliated Hospital of Jiamusi University from January 2016 to June 2019 were prospectively collected. MAIN MEASURES: The quality of life was assessed using four patient-reported outcome measures (PROMs): the 15D questionnaire, Oral Health Impact Profile-14 (OHIP-14), Hospital Anxiety and Depression Scale (HADS), and 36-item Short Form Survey (SF-36)...

Reconstruction of the bony orbit in patients with combined midface injuries is frequently discussed in the current literature. Two main concepts can be distinguished: single-stage reconstruction, usually with a hand-bent titanium orbital mesh, and two-stage reconstruction, in which osteosynthesis of the zygomaticomaxillary complex (ZMC) is followed by orbital reconstruction with a virtually-planned, patient-specific titanium implant in a second surgery. This study aimed to compare one-stage and two-stage surgical approaches on combined midface fractures regarding postoperative diplopia...

Penetrations of the nasal cavity through the zygomaticomaxillary bone by wooden foreign bodies have not been reported yet. Wooden foreign bodies, characterized as hypodense signals resembling air bubbles on computed tomography scans, could increase the risk of infection and abscess formation if left untreated. Therefore, any possible attempts to remove it entirely should be made in a timely manner. Also, regarding removal surgery, the complications of the surgery, such as massive bleeding or iatrogenic injury to the adjacent structure, should be considered, especially in the paranasal area...

Among zygomaticomaxillary complex (ZMC) fractures presenting to a tertiary urban academic center, the authors hypothesized the presence of both clinical and radiographic predictors of operative management. The investigators conducted a retrospective cohort study of 1,914 patients with facial fractures managed at an academic medical center in New York City between 2008 and 2017. The predictor variables were based on both clinical data and features of pertinent imaging studies, and the outcome variable was an operative intervention...

METHODS: This prospective cohort study was conducted on cases of ZMC fractures. The inclusion criteria were displaced tetrapod zygomatic factures, asymmetry of the facial bones, and unilateral lesion. The exclusion criteria were extensive skin or soft tissue loss, comminuted inferior orbital rim, limited ocular mobility, and enophthalmos...

Introduction: Orbital floor (OF) fractures accompany all zygomaticomaxillary complex (ZMC) fractures, but guidelines for repair of OF fractures in this setting are unclear. Objectives: To compare ophthalmologic outcomes of ZMC repair with and without concurrent OF repair. Methods: We retrospectively reviewed patients undergoing ZMC fracture repair with and without OF repair between 2016 and 2018. Patients were reviewed for demographics, preinjury characteristics, and ophthalmologic outcomes. Results: Of 61 total patients, 32 underwent concomitant OF repair while the remaining 29 underwent ZMC repair alone...

Zygomaticomaxillary complex and isolated orbital walls fractures are one of the most common fractures of the midface, often presenting orbital symptoms and complications. Our study was born with the aim of understanding the trend in the incidence of orbital presurgical symptoms, specifically diplopia, enophthalmos and exophthalmos, in the Campania Region in southern Italy. We conducted a retrospective, monocentric observational study at the Maxillofacial Surgery Unit of the Federico II University Hospital of Naples, enrolling 402 patients who reported a fracture of the zygomaticomaxillary complex and orbital floor region from 15 June 2021 to 15 June 2022...

Anatomic reduction of Zygomaticomaxillary complex (ZMC) fractures is quite challenging and technically demanding. Various methods and instruments are mentioned in the literature to achieve the same. However, a precise anatomic reduction is still a difficult task. We propose the use of a simple orthopaedic impactor in reducing laterally rotated ZMC fractures.

There has been always a need of new methods to control post operative complications in OMFS. A randomized prospective study was done to assess the effect of K tape on postoperative swelling, pain, trismus in Zygomatico-maxillary Complex (ZMC) fracture after open reduction with internal fixation using two point fixation. 30 patients of either gender undergoing ORIF for ZMC fracture using two point fixation of age group between 18 and 50 years were included in the study. Patients were divided into treatment either with or without Kinesiologic tape...

INTRODUCTION: The intra-oral skeletally anchored maxillary protraction (I-SAMP) has been found to be an effective treatment for skeletal Class III malocclusion. OBJECTIVE: This in-silico study explored the influence of different force directions of intra-oral skeletally anchored Class III elastics on the changes in craniomaxillofacial complex, using finite element analysis. METHODS: A 3-dimensional (3D) finite element model of the craniomaxillofacial bones including circummaxillary sutures was constructed with high biological resemblance...

PURPOSE: The present study aims to investigate how well CT images correlate to surgical findings in orbital floor fractures and to the presence of diplopia. METHODS: In this cross-sectional study, 27 consecutive patients already selected for surgery due to an orbital floor fracture underwent a routine CT scan (axial, coronal, sagittal). An ophthalmologist established any presence of diplopia. Extent of fracture/injury seen on CT was compared to that discovered during surgery...

AIM AND OBJECTIVES: The study aims to assess the incidence and features of temporomandibular joint(TMJ) dysfunction in post-surgical treatment of unilateral zygomaticomaxillary complex(ZMC) fractures.The objectives are:To assess severity of TMJ dysfunction in postoperative cases of ZMC fractures.To create awareness of the same among clinicians. METHODS: Patients presenting with zygomaticomaxillary complex fractures were evaluated prospectively. Evaluation of TMJ dysfunction was done by different parameters via questionnaire, clinical and radiographic examination preoperatively and a follow-up period of 1 week, 3 months and 6 months...

The purpose of the study was to measure the maxillary sinus sizes in patients with and without zygomatic bone fractures. In this cross-sectional study computed tomography data of a case group of consecutive treated patients with displaced zygomatic bone fractures were compared to a control group with mandibular fractures. Maxillary sinus sizes were measured in width, height, depth, and volume. We compared sinus sizes between the case and control group, followed by a subgroup analysis of slightly and severely displaced fractures using T-tests...

INTRODUCTION: The incidence of ocular injury associated with maxillofacial trauma remains poorly defined, with reported rates ranging from 0.8% to 92%. Our study aims to more accurately characterize ocular injuries associated with midface fractures. METHODS: We performed a retrospective review of 1677 patients from 2015 to 2020 with midface fractures at a Level I trauma center. Isolated nasal bone and frontal process of the maxilla fractures were excluded. Demographic information, mechanism of injury, need for surgery, and ophthalmologic findings were documented...

Purpose: The aim of our study was to evaluate the feasibility of an intraoral approach in the management of infraorbital rim fracture. Patients and Methods: A total of 12 patients of which four were female and five were male with isolated unilateral zygomaticomaxillary complex (ZMC) fractures, essentially involving the infraorbital foramen (right or left), were included in this study. Indications for surgical intervention were cosmetic deformity, disturbance of vision, persistent paresthesia, or impaired mandibular movement...

The aim of this retrospective study was to compare mid-facial symmetry and clinical outcomes between patients treated with patient-specific and standard implants in primary fracture reconstructions of combined orbital and zygomaticomaxillary complex fractures. Patients who underwent primary reconstruction of orbital and zygomaticomaxillary complex fractures during the study period were identified and background and clinical variables and computed tomography images were collected from patient records. Zygomaticomaxillary complex dislocation and orbital volume were measured from pre- and postoperative images and compared between groups...

BACKGROUND: Traditionally, in zygomaticomaxillary complex and orbital fractures, miniplates and titanium orbital mesh are used and adapted intraoperatively, which may cause fatigue of the metal and increase the surgical time. Recently, computer-assisted surgery and 3-dimensional printing enable the surgeon to employ 3-dimensional segmentation and mirroring tools, which mimic the pretraumatized anatomy on which the miniplates and titanium orbital mesh are preoperatively molded to precisely duplicate the orbital volume, enophthalmos, and zygomatic bone position...

BACKGROUND: Zygomaticomaxillary complex fractures involve four fracture ends. It is difficult to fully expose the operative area through a main coronal incision, an intraoral incision, and an eyelid incision. To address the partial visual field loss in craniofacial fracture reduction, we attempted to use an augmented reality (AR) navigation system. METHODS: Patients with zygomaticomaxillary complex fractures underwent three-dimensional (3D) computed tomography (CT) modeling before surgery, and preoperative plans were designed...

Rationale: An orbital fracture is said to be a pure blowout when it affects only one internal orbital wall and does not compromise the orbital rim. Pure blowout fracture of the orbital floor without any other associated facial bone fracture is uncommon. Patient Concerns: The patient with a history of assault presented with complaints of blurring of vision and diplopia. Diagnosis: Computed tomography of paranasal sinus scans and ophthalmologic examination confirmed the right orbital floor fracture...
