Zmc fracture

Fixation is critical in zygomaticomaxillary complex (ZMC) fractures to avoid malunion; however, controversy exists as to how much hardware is required to achieve adequate stability. Current fixation regimens may not represent the minimum stabilization needed for uneventful healing. Craniomaxillofacial (CMF) computational models have shown limited load transmission through the infraorbital rim (IOR), and a previous experimental study of ZMC fractures has suggested that IOR plating does not alter CMF bone strain patterns...

INTRODUCTION: Reduction of zygomaticomaxillary (ZMC) fracture is often difficult to evaluate intraoperatively because of it peculiar anatomy and limited accessibility. The purpose of this study is to evaluate the efficacy of use of C-arm as a tool for intraoperative monitoring of ZMC fracture reduction. MATERIALS AND METHODS: Group I (C-Arm) and Group II (control group) comprised of patients with isolated unilateral displaced Zygomatic complex (ZMC) fractures and having orbital volume change...

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...

PURPOSE: The application of a computer-aided navigation system (CANS) in zygomatic complex (ZMC) fractures has been extensively reported, but individual results are heterogeneous. The purpose of this systematic review was to evaluate the role of CANS in the surgical treatment of unilateral ZMC fractures. METHODS: Electronic retrieval of MEDLINE, Embase, and Cochrane Library (CENTRAL) and manual searching until November 1, 2022 were used to identify cohort studies and randomized controlled trials employing CANS in the surgical treatment of ZMC fractures...

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...

BACKGROUND: Standing electric scooters (e-scooters) are a cost-effective and environmentally-friendly transport alternative, but also elicit substantial concern regarding associated craniofacial injuries. This study aims to describe the patient factors, procedural factors and post-operative outcomes of maxillofacial fractures caused by e-scooter accidents. METHODS: Retrospective chart review of patients aged 18 years or older who were surgically treated for these injuries in 2014-2020 at two Australian tertiary hospitals...

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...

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: Fractures of the zygomatic-maxillary complex (ZMC) are common facial fractures. After adequate fracture reduction, it is important to maintain stability and rigid fixation to avoid functional impairment and aesthetic sequelae. In this sense, the fixation of just one point can provide sufficient stability of the ZMC fracture when the ZMC fracture is not crushed. OBJECTIVE: To analyze the success rates of fracture stability of the ZMC, incidences of complications, and aesthetic satisfaction after 1-point fixation...

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...

STUDY DESIGN: This was a retrospective cohort study of the 2014 Nationwide Emergency Department Sample (NEDS). OBJECTIVE: Intraoral and submental projectile entry points may be less fatal than other facial entry points due to the indirect access to the intracranial structures and the protection offered by the intervening maxillofacial complex. Because intraoral and submental trajectories are almost always present in the setting of attempted suicide, this study sought to determine if intent (self-harm versus other-harm) influenced mortality in facial gunshot wound (GSW) patients...

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...

OBJECTIVES: To determine the incidence and types of ophthalmic complications associated with maxillofacial trauma over a period of 24 months. METHODS: An institutional prospective study was conducted on 62 patients presenting with maxillofacial trauma to study the correlation between facial trauma and ophthalmic complications. RESULTS: Road traffic accidents were reported to be the primary etiologic factor for most trauma cases studied.
