Study Overview
Brief Summary
Rationale: Facial trauma is a significant event for patients, often resulting in physical and psychological consequences. Fractures in the zygomatic bone area are common due to its unique shape and positioning in the face, disrupting facial symmetry and impacting aesthetics, functionality, and psychological well-being. The zygomatic bone, crucial for facial contour and support, is associated with complications such as diplopia, sensory disturbances, and mastication problems when fractured. Treatment aims to restore function, aesthetics, and prevent long-term deformities. Despite surgical and imaging advancements, postoperative complications like residual deformity and dissatisfaction persist. Even with achieved bone symmetry, patients may perceive asymmetry. Current literature emphasizes the need for future symmetry analyses to include both soft and hard tissues.
Objective: This study aims to evaluate the long-term outcomes of zygomatic fracture treatments at Erasmus MC from 2008 to 2023.
Study design: Cross-sectional study Study population: The study population consists of adult patients aged 18 years and above diagnosed with zygomatic fractures and treated at Erasmus MC Rotterdam between 2008 and 2023.
Intervention: Not applicable Main study parameters/endpoints: The primary endpoint is patient satisfaction and quality of life.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Cone Beam Computed Tomography (CBCT) is an advanced imaging modality utilized for high-resolution three-dimensional (3D) visualization of the maxillofacial region. It employs a rotating C-arm apparatus to project a cone-shaped X-ray beam through the patient's head, yielding detailed images with minimal distortion. CBCT is pivotal in the diagnosis and assessment of maxillofacial conditions, including zygomatic fractures, while ensuring low radiation exposure. Over the past two decades, CBCT has been extensively integrated into dental and maxillofacial imaging, with numerous studies substantiating its efficacy and safety in clinical contexts. It serves as a cornerstone in orthodontic, implantological, and trauma evaluation, supported by a substantial body of evidence validating its ability to delineate bone structures and identify fractures. Human exposure to CBCT has demonstrated a robust safety profile, characterized by radiation doses lower than those of conventional CT scans, thus imparting negligible additional risk.
Detailed Description
- INTRODUCTION AND RATIONALE
Facial trauma represents a significant event in a patient's life, often resulting in physical deformities and potential psychological consequences (1, 2). In facial trauma cases, fractures occurring in the zygomatic bone area are prevalent due to the distinctive shape and positioning within the face (3, 4). These fractures can disrupt the facial symmetry, which plays a role in the perceived aesthetics and functionality of the human face, impacting not only physical appearance but also psychological well-being and social interactions (5).
The zygomatic bone, a critical component of the midfacial skeleton, contributes to the contour and width of the face, supports the orbit and has a functional role as the origin of one of the masticatory muscles, the masseter muscle (6). Therefore, fractures in this region can lead to a variety of complications including diplopia, enophthalmos, sensory disturbances and mastication problems (7). Treatment aims not only to restore function and aesthetics but also to prevent long-term deformities.
Despite advancements in surgical techniques and imaging modalities (8), postoperative complications such as residual deformity, asymmetry of hard and soft tissue, and dissatisfaction with facial appearance remain remain concerns that warrant further investigation. Even when bone symmetry is achieved, patients may still report perceived asymmetry (9). Current literature, primarily focused on hard tissue symmetry, indicates the necessity of including both soft and hard tissues in future symmetry analyses (10).
This study aims to create a detailed database of patients treated for zygomatic fractures at Erasmus MC from 2008 to June 2023. By leveraging data from electronic patient records, we intend to gather extensive demographic, clinical, and treatment-related information. Following this, patients will be invited to undergo additional evaluations including Cone Beam Computed Tomography (CBCT) scans, which offer precise imaging to assess for any residual displacement and asymmetry. For soft tissue, 3D facial photography will be used to objectively measure facial asymmetry, offering a comprehensive view of both functional and aesthetic results post-recovery. Patient satisfaction and quality of life post-treatment will be assessed through validated questionnaires (FACE-Q), providing insights into the psychological and social impacts of these injuries. Functional tests will be conducted to evaluate ocular motility and cutaneous sensory function.

Time Frame: 1 year
The primary objective of this study is to evaluate the long-term outcomes of patients treated for zygomatic fractures at Erasmus MC from 2008 to 2023. Specifically, to assess patient satisfaction with facial appearance and overall quality of life post-treatment using validated questionnaires. This will provide insights into the psychological and social impacts of zygomatic fractures and their treatment.
