NCT06850857
The goal of this observational study is to validate a novel patient-reported outcome measure (PROM) for patients suffering maxillofacial trauma: The Integrated Modular Patient-Reported Outcome Assessment for Craniomaxillofacial Trauma (IMPACT). The primary question is: Are the IMPACT modules valid and reliable measures to study quality-of-life (QOL) in patients with maxillofacial trauma? Patients presenting for routine clinic follow-up for maxillofacial trauma will be invited to complete the IMPACT in addition to the 15 Dimension (15D) QOL survey as a control.
NCT07012850
Dental, oral, and maxillofacial trauma represents a significant public health concern, with most cases resulting from accidents and occurring frequently in young adults. Diagnosis relies on clinical examination and imaging modalities like computed tomography (CT) and cone-beam computed tomography (CBCT), which are standard for hard tissue assessment but expose patients to ionizing radiation. To reduce radiation exposure while simultaneously allowing for the visualization of soft tissues, newer imaging methods, including magnetic resonance imaging (MRI), as well as Black Bone and CT-like MRI protocols (ZTE, UTE), are being explored. These MRI techniques offer high-resolution, non-ionizing alternatives, showing promise for diagnosing soft tissue injuries and fractures without radiation risks, especially beneficial for younger patients. This study aims to assess MRI's diagnostic capabilities for maxillofacial trauma, focusing on early diagnosis, artifact reduction, and comparison to conventional X-ray-based imaging, within a minimal-risk study framework. This study aims to evaluate the diagnostic efficacy of MRI compared to X-ray-based imaging modalities (CT/CBCT) for detecting dental, oral, and maxillofacial fractures, with a specific focus on Black Bone and CT-like MRI techniques. Additionally, it investigates MRI's potential to reduce artifacts around osteosynthesis plates, enhancing postoperative imaging quality in the presence of metal hardware.
NCT05699187
Face allotransplantation will be performed in facial trauma patients. Immune suppression will primarily be provided according to standard three-drug regimen. The primary outcome to be evaluated in the proposed trial is face allograft acceptance.
NCT02158793
The purpose of this study is to perform face transplants on people who have suffered severe facial trauma with tissue and functional loss; and evaluate the acceptance and function of the transplanted tissue. The aim of the transplant is to provide patient a more normal appearance . Additionally we aim to restore functioning, movement, and sensation of their face including that of the lips, mouth, and eyes.
NCT06163209
The purpose of this cross-sectional prospective observational study is to determine the efficacy of high-resolution ultrasonography in identifying and characterizing nasal bone fractures in adult patients with recent facial trauma. The primary questions it aims to answer are: * Can high-resolution ultrasonography effectively detect nasal bone fractures? * Is high-resolution ultrasonography capable of indirectly detecting septal fractures? * What are the specificity and sensitivity of high-resolution ultrasonography in comparison to computed tomography scan? Participants will undergo examination and treatment in accordance with current standards for nasal fracture management. Additionally, high-resolution ultrasonography will be performed during the initial physical examination, preceding any therapeutic interventions.
NCT05814991
It is very important to decrease the bleeding during bimaxillary osteotomy in order to increase the visibility of the surgical site. Our primary goal is to investigate the predictive value of pre- and perioperative factors, including controlled hypotension, on visibility of surgical site during bimaxillary osteotomy.
NCT03314480
The aim is to prospectively assess the association between clinical parameters and the presence of maxillofacial fractures in trauma patients admitted to the emergency department. Our hypothesis is that a clinical decision aid of critical parameters reduces unnecessary produced CT scans in maxillofacial trauma patients.

Medical titanium plates are routinely used in fixing mobilized bone segments in jaw surgeries. Generally these plates are commercialized with standard construction specifications. Thus they should be repeatedly bended and arched to match the contour of anchored jaw bones before located in place and fastened by screws. To prevent stress fatigue induced by plate bending and improve structural design, we utilized the three-dimensional printing technique and developed a new production procedure in fabricating customized titanium plates according to each patient's specific skeletal contours and dimensions derived from medical imaging data. In general, the three-dimensional printing of customized implants are expected to facilitate surgical operation, reduce application duration and improve precise restoration. Up until now, the application of three-dimensional printing of titanium fixation plates in jaw surgery has been available only at two centers globally. The published preliminary work have proved the prospect of customized titanium plates in promoting mandibular reconstruction surgery and upper maxilla orthognathic surgery though their printed titanium plates looked rather bulky and the sample sizes were small and there is still lack of qualified randomized controlled trials between the printed and the conventional titanium plates. To better benefit from the burgeoning use of three-dimensional printing in health care, it is imperative to conduct a feasibility study in exploring the application of three-dimensional printing of titanium fixation plates in jaw surgery based on our patients. The aim of the study is to conduct a case series study focusing on the feasibility and safety of applying three-dimensional printed titanium plates in jaw reconstruction surgery and orthognathic surgery. The outcome measures include the success rate, potential adverse events and accuracy. A sample size of 48 subjects will be recruited prospectively. Considering the facts that titanium plates are widely used in jaw surgery and our unit is the largest oral and maxillofacial surgery center in Hong Kong, the well-designed customized titanium plate is therefore with great potential benefit for the patients in our population. Furthermore, the well-developed three-dimensional manufacturing protocol could also be applied in other relevant medical areas and push forward the personalized medicine era in the future.
