    Abstract 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.
    Results: There were 18 cases included. Most cases were male (66%). The mean age was 35 years. Common risk factors were alcohol use (86%) and lack of helmet use (62%). The most common fracture pattern was zygomatico-maxillary complex (ZMC) fractures (50%). There were no associated systemic injuries. Mean operation timing was 12 days post-injury for ZMC fractures and 3 days post-injury for condyle fractures. For ZMC fractures, the most common method of fixation was 2-point fixation (66%). For condyle fractures, the most common surgical approach was arch bars only (83%). Post-operative complications were reported in six cases, with malocclusion being the most common (n = 3). Revision surgeries were performed in two cases.
    Conclusions: Maxillofacial fractures associated with e-scooter accidents appear to be increasing in incidence. Robust longitudinal evaluations with larger sample sizes are required to better understand associated presentations, surgical approaches and post-operative complications.

    Abstract Orbital reconstruction is a common procedure with inherent challenges and important consequences. Intraoperative use of computed tomography (CT) is an emerging application that facilitates accurate intraoperative evaluation to improve clinical outcomes. This review aims to investigate the intraoperative and postoperative outcomes of intraoperative CT use in orbital reconstruction. PubMed and Scopus databases were systematically searched. Inclusion criteria were: clinical studies investigating intraoperative CT use in orbital reconstruction. Exclusion criteria were: duplicates; non-English publications; non-full-text publications; studies with insufficient data. Of the 1022 articles identified, seven eligible articles representing 256 cases were included. The mean age was 39 years. Most cases were male (69.9%). With regards to intraoperative outcomes, the mean revision rate was 34.1%, with plate repositioning being the most common type (51.1%). Intraoperative time was variably reported. With regards to postoperative outcomes, there were no revisions, and only one case that had a complication (transient exophthalmos). Mean volumetric difference between the repaired and contralateral orbits was reported in two studies. The findings of this review present an updated evidence-based summary of the intraoperative and postoperative outcomes of intraoperative CT use in orbital reconstruction. Robust longitudinal comparisons of clinical outcomes between intraoperative and non-intraoperative CT cases are required.

    Abstract Concomitant traumatic brain injury (TBI) and maxillofacial fractures carry the risk of significant morbidity and mortality. The aim of this review was to explore the demographics, types of injury, and complications of traumatic maxillofacial and brain injuries, in order to contribute to comprehensive health strategies. The PubMed and Scopus databases were systematically searched. Inclusion criteria were clinical studies investigating combined traumatic maxillofacial and brain injuries. Exclusion criteria were duplicates, non-English publications, non-full-text publications, publication date before 1990, and studies with insufficient data. Of the 754 articles identified, 15 eligible articles representing 1421 cases were included. The mean age was 38.3 years. Most cases were male (79%). The most common mechanism of injury was traffic accidents (53.4%). The most common fracture pattern was middle third fractures (52.4%). Seven studies had an explicit definition for TBI, using the Glasgow Coma Score (GCS), radiological evidence, and/or specific symptoms. There were 147 complications reported in 62 of 253 cases (24.5%), with the most common being infection (n=54, 36.7%). Significant risk factors for complications included delayed surgical repair, low GCS, and upper third fractures. Robust longitudinal evaluations with clear definitions of TBI are required. Gaps in knowledge include risk factors for complications and fracture pattern-GCS correlations.

    Abstract The surgical management of head and neck pathologies involving the maxilla and mandible results in significant functional and aesthetic deficits, and ultimately reduced quality of life. Composite free flaps used for reconstruction address many of these deficits and create a foundation for the use of osseointegrated implants to support prosthetic replacement of the dentition. There are few comparative studies examining outcomes of implants in native and reconstructed bone in head and neck cancer patients. The aim of this retrospective cohort study was to compare survival rates and the effects of risk factors between implants placed in native and reconstructed bone. The Kaplan-Meier method estimated cumulative 1- and 5-year implant survival rates of 99.5% and 95% for native bone and 96% and 88% for reconstructed bone. Multivariate Cox regression found an increased risk of implant failure in reconstructed bone (hazard ratio (HR) 9.9, 95% confidence interval (CI) 3.4-29.7, P<0.001). Subgroup analysis of the cohorts found an increased risk of failure in the reconstructed group associated with radiotherapy (HR 6.4, 95% CI 1.8-22.3, P=0.004), current smoking (HR 23.2, 95% CI 2.7-198.6, P=0.004), and previous smoking (HR 9.0, 95% CI 1.1-71.9, P=0.038). There was no effect in the native bone group. Implants placed into reconstructed bone had higher rates of failure, and smoking status and radiotherapy increased the risk of implant failure.

    Abstract Study design: Systematic review.
    Objective: Standing electric scooters (e-scooters) provide a cheap and environmentally friendly transport alternative, but also elicit substantial concern regarding their volume of associated injuries especially in the craniofacial region. This review aims to explore the demographics, risk factors, types of injury and surgical management of craniofacial trauma associated with e-scooters.
    Methods: PubMed and Scopus databases were systematically searched. Inclusion criteria were clinical studies investigating craniofacial trauma associated with e-scooters. Exclusion criteria were duplicates; non-English publications; non-full-text publications; studies with insufficient data.
    Results: Of the 73 articles identified, 10 eligible articles representing 539 patients were included. The mean age was 31.5 years. Most cases were male (63.7%). Common risk factors were alcohol/drug intoxication, absence of distal extremity injuries and lack of helmet use. The most common mechanism of injury was mechanical falls (72.4%). The most common facial fracture pattern was middle third fractures (58.3%). Surgical management was required for 43.3% of fractures. Other types of injuries reported were traumatic brain injuries (17.6%), soft tissue injuries (58.3%), dental injuries (32.9%) and ophthalmological injuries (20.6%).
    Conclusions: The findings of this review suggest common presentations for craniofacial trauma associated with e-scooters. Robust longitudinal evaluations with standardised descriptions of types of injuries are required. Gaps in knowledge relate to surgical management, post-operative complications and associated risk factors.

    Abstract Several cost-efficient, high-resolution modeling approaches are applied to simulations of the Southern Ocean in past, present, and future climates. The results are compared with an ensemble of medium-resolution, eddy-present simulations and evaluated based on their ability to reproduce observed mesoscale activity and to reveal a response to climate change distinct from natural variability. The high-resolution simulations reproduce the observed magnitude of Southern Ocean eddy kinetic energy (EKE) well, but differences remain in local magnitudes and the spatial distribution of EKE. The coarser, eddy-present ensemble simulates a similar pattern of EKE but underrepresents observed levels by 50 %. Five years of simulated data in each time period is found to produce consistent results when evaluating mean conditions and assessing change in the region as a whole. At 1 °C of warming, the high-resolution simulations produce no change in overall EKE, in contrast to the increase projected by the eddy-permitting ensemble and despite full ensemble agreement. At 4 °C of warming, both datasets produce consistent levels of EKE rise in relative terms, although not absolute magnitudes, as well as an increase in EKE variability. Simulated EKE rise is concentrated where flow interacts with topographic features in regions already known to be eddy-rich. Regional EKE change in the high-resolution simulations is consistent with changes seen in at least four of five eddy-permitting ensemble members at 1 °C of warming, and all ensemble members at 4 °C. However, substantial noise would make these changes difficult to distinguish from natural variability without an ensemble.
