Facial Trauma in E-Scooter vs. Bicycle Accidents: A Retrospective Comparative Analysis in a Metropolitan Setting

The increasing prevalence of E-Scooters has led to a rise in related injuries, particularly affecting the maxillofacial region. While bicycle-related facial trauma is well-documented, comparative data on E-Scooter injuries remain rare. This study aims to analyze and compare facial trauma patterns between E-Scooter and bicycle accidents in a metropolitan setting.

A retrospective analysis was conducted at the Department of Oral and Maxillofacial Surgery, including patients with facial trauma from E-Scooter or bicycle accidents between January 2023 and July 2024. Demographic data, accident characteristics, and injury patterns, including dental trauma, soft tissue injuries, and fractures, were analyzed using Chi-squared tests, independent t-tests, and Fisher's exact test.

A total of 272 patients were included, with 84 (30.9%) sustaining E-Scooter-related injuries and 188 (69.1%) bicycle-related injuries. E-Scooter users were significantly younger (36.5 ± 12.4 vs. 47.0 ± 14.2 years, p < 0.001) and more often female (64.3% vs. 33.0%, p < 0.001). Dental trauma was frequent in both groups, but tooth avulsions were significantly more common in E-Scooter accidents (53.6% vs. 19.7%, p < 0.001). Mandibular and nasal fractures occurred more frequently in E-Scooter users, while bicycle accidents resulted in more zygomatic and Le Fort fractures.

E-Scooter and bicycle accidents exhibit distinct facial trauma patterns, likely due to differences in injury mechanisms. These findings highlight the need for enhanced safety regulations, including the wearing of protective gear and targeted prevention strategies for E-Scooter users.
