Rising Incidence of Maxillofacial Fractures Linked to E-Scooter Accidents

Australia: Researchers from the University of Queensland have conducted a comprehensive multi-centre retrospective review focusing on the connection between standing electric scooters (e-scooters) and maxillofacial fractures. 

E-scooters have gained popularity as a cost-effective and environmentally-friendly mode of transportation. However, they have also raised significant concerns regarding associated craniofacial injuries. The study aims to provide insights into patient factors, procedural factors, and post-operative outcomes of maxillofacial fractures caused by e-scooter accidents.

Analysis of Patient Data

The retrospective chart review encompassed patients aged 18 years and older who underwent surgical treatment for e-scooter-related maxillofacial fractures between 2014 and 2020 at two Australian tertiary hospitals. A total of 18 cases were included in the study, with the majority being male (66%). The mean age of the patients was 35 years. Common risk factors identified were alcohol use (86%) and lack of helmet use (62%).

Fracture Patterns and Surgical Approaches

Among the observed cases, zygomatico-maxillary complex (ZMC) fractures were the most prevalent, accounting for 50% of the cases. There were no associated systemic injuries reported. The mean time to operation was 12 days post-injury for ZMC fractures and 3 days post-injury for condyle fractures. In terms of surgical methods, 2-point fixation was the most common approach for ZMC fractures (66%), while arch bars alone were predominantly used for condyle fractures (83%).

Post-operative Outcomes and Complications

Six cases reported post-operative complications, with malocclusion being the most frequently encountered issue (n = 3). Two cases required revision surgeries to address complications. It is noteworthy that no systemic complications were identified among the study participants.

The findings of this retrospective review indicate an increasing incidence of maxillofacial fractures associated with e-scooter accidents. However, the study acknowledges the necessity for robust longitudinal evaluations with larger sample sizes to gain a more comprehensive understanding of associated presentations, surgical approaches, and post-operative complications. Further research is crucial to inform preventive measures and improve treatment strategies in addressing e-scooter-related injuries.

The University of Queensland’s study provides valuable insights into the growing concern of e-scooter-related maxillofacial fractures. As the use of e-scooters continues to rise, understanding the risks and developing appropriate preventive measures becomes imperative to ensure the safety of riders and reduce the incidence of such injuries.
