Zmc fracture

Posttraumatic and postsurgical sensory disturbance is a known complication of almost all zygomaticomaxillary (ZMC) complex fractures involving the infraorbital nerve, for which few treatments are effective. Our study used neurosensory assessments to evaluate the efficacy of melatonin on pain and nerve healing following ZMC surgery. Sixty-four randomly allocated ZMC fracture patients were prophylactically administered either oral melatonin or an identical placebo for 15 consecutive days. Pre- and postsurgical clinical parameters included subjective pain, numbness, and objective neurosensory function...

Attitudes towards healthcare in the NHS and in other Western healthcare systems have been changing dramatically in recent years. There is a significant movement calling for a shift from the traditional paternalistic model, with patients as passive recipients of treatments that are supported by objective and observable evidence, towards a more holistic approach, in which patients have agency, and treatments are tailored to the individual needs of a particular patient. Whilst patient safety and clinical effectiveness remain intrinsic to the traditional measurement of successful healthcare, Patient Reported Outcome Measures (PROMs) are increasingly being advocated as an important tool to uphold patient-centric care in the NHS...

Objective: To compare the effectiveness of 2DCT and 3DMR formats used for patient education on facial fractures, as measured by surveys. Methods: In this prospective, randomized, crossover study, video tutorials intended for facial fracture informed consent were created in 2DCT and 3DMR formats from a single CT data set of a zygomaticomaxillary complex (ZMC) fracture...

Zygomaticomaxillary complex fractures are very common in maxillofacial trauma and may be associated with fractures of the coronoid process. We report a case of dislocation of the coronoid process above a zygomaticomaxillary complex fracture locking the mandible. We also report the surgical management of this uncommon case and its follow-up.

Our study aimed to evaluate modified patient-specific surgical-guide-assisted precise treatment of unilateral comminuted zygomaticomaxillary complex (ZMC) fractures. The retrospective non-randomized study was conducted in a single hospital in China. All patients diagnosed with unilateral comminuted ZMC fractures between January 1, 2018 and December 31, 2022 were retrospectively reviewed. All patients underwent preoperative spiral computed tomography (CT). CT data were processed using software to DICOM format and transferred to Proplan CMF3...

Zygomaticomaxillary complex (ZMC) fracture repair is one of the most common surgical procedures performed in craniomaxillofacial trauma management. Miniplates and screws are used to stabilize the fractured bone using small local incisions, however, these procedures are not infrequently associated with hardware-related post-operative complications. The amount of fixation hardware utilized varies depending on the fracture pattern and surgical judgment, with three-point fixation being the conventionally accepted treatment...

BACKGROUND: One-point fixation was superior to the two and three-points fixation in minimally displaced zygomaticomaxillary complex (ZMC) fracture regarding the cost, invasiveness, scaring, number of wounds, and operation time. Accordingly, this study aimed to predict which one-point fixation is the most stable in managing minimally displaced ZMC fracture. MATERIAL & METHODS: This study simulated the different one-point fixation approaches on three ZMC models after fracture reduction and application of all forces exerted on the fractured area...

STUDY DESIGN: A prospective randomized comparative study was conducted to evaluate the postsurgical scar with Supraorbital Eyebrow (SE) Approach and Upper Blepharoplasty (UB) Approach used for open reduction and internal fixation (ORIF) of zygomaticomaxillary complex (ZMC) fractures. OBJECTIVE: To evaluate and compare the post-operative scar using Vancouver Scar Scale (VSS) following ORIF of ZMC fractures with SE and UB approaches. METHODS: In this study, 88 patients with ZMC fractures requiring ORIF and meeting the inclusion criteria were recruited between 2019 and 2020...

Orofacial injuries constitute the medico-legal cases reported, especially, in cases associated with road traffic accidents, assaults, and violence making it an emerging healthcare problem. Therefore, it is of interest to document data on the maxillofacial trauma and fractures among Indians. 150 subjects within the age of 15 to 60 years with maxillofacial fractures, detailed medical history including demographics, radiographs, medical history, associated injuries, and etiology of fractures were used for this study...

BACKGROUND: Limited research exists regarding the incidence and variations of zygomaticomaxillary complex (ZMC) fracture patterns and their correlation with the mechanism of injury. Hence, further research is indicated. PURPOSE: The purpose of this study was to analyze the different ZMC fracture patterns in relation to its etiology using computed tomography scans. STUDY DESIGN, SETTING, SAMPLE: This retrospective cohort study was conducted at a single institution...

BACKGROUND: Due to the complex anatomical morphology and lack of anatomic markers on the surface of zygomatic complex (ZMC), the treatment results of ZMC fractures are often suboptimal. PURPOSE: The study aimed to evaluate the effectiveness of intraoperative computed tomography (ICT) in the treatment of unilateral ZMC fractures, and further study the feasibility of ICT to replace early postoperative Computed Tomography (CT). STUDY DESIGN, SETTING, AND SAMPLE: The investigators designed a retrospective cohort study...

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: With little evidence available in the literature, this study tries to clinically determine the efficiency and outcomes of non-surgical management of post-traumatic Zygomaticomaxillary complex (ZMC) fractures. MATERIALS AND METHODS: One hundred and three patients with post-traumatic isolated ZMC fractures managed conservatively for various reasons were identified. The patients were classified based on the Zingg et al. criteria into Types A, B, and C...

A sagittal fracture at the temporal root of the zygomatic arch (ZAR) often occurs as a component of zygomaticomaxillary complex (ZMC) fractures. However, this area is difficult to access, and anchorage is limited due to the unstable structure around it. Therefore, a preauricular approach using single-screw fixation is proposed, and this study reports its results and usefulness. Forty-four patients with sagittal fractures of ZAR occurring with ZMC fractures were evaluated from 2012 to 2021. Open reduction and internal fixation were performed on all patients with ZMC fractures...

Given the demands of a busy high-volume trauma center, trauma radiologists are expected to evaluate an enormous number of images covering a multitude of facial bones in a short period of time in severely traumatized patients. Therefore, a comprehensive checklist, search pattern, and practical approach become indispensable for evaluation. Moreover, fracture complex classification conveys abundant information in a succinct shorthand fashion, which can be a large asset in a busy high-volume trauma center: reliably helping clinicians communicate urgent findings, make early treatment decisions, and effectively plan surgical approaches...

PURPOSE: This study aimed to assess the maxillary sinus volume (MSV), Chronic Sinusitis incidence, and asymmetry of the zygomaticomaxillary complex (ZMC) following ZMC fracture surgery with various numbers of fixation points. MATERIALS AND METHODS: In a prospective non-randomized cohort, 50 adults with unilateral ZMC fractures who treated by open reduction and internal fixation (ORIF) between November 2019 and October 2021 were assigned to accomplish this study...

Regarding the three distinct types of zygomaticomaxillary complex (ZMC) fractures, this study developed finite element models (FEMs) of absorbable material and titanium material for repair and fixation, respectively. By applying a force of 120N to the model to simulate the masseter muscle strength, the maximum stress and displacement of the repair materials and the fracture ends were measured. In discussing various models, the maximum stress values of absorbable and titanium materials are less than their yield strength, and the maximum displacement values of the titanium material and fracture end were less than 0...
