Abstract:
<u>Background</u>:<br> Although helmets reduce traumatic brain injury, their role in mitigating facial trauma remains uncertain. Riders continue to sustain complex facial fractures despite helmet use, raising questions about how helmet use and vehicle type affect injury severity. <br><u> Learning Objective</u>: <br> To understand how helmet use influences facial fractures. <br><u> Study Objective</u>:<br> To assess whether helmet use in cycling and open-vehicle accidents alters the severity, operative burden, and outcomes of facial fractures. <br><u> Design Type</u>:<br> Retrospective cohort study. <br><u> Method</u>:<br> A 10-year retrospective review (2012–2022) identified patients with facial fractures from open-vehicle and cycling accidents. Helmet use, injury mechanism, and outcomes -- including severe injury (ICU admission or TBI), surgery, operative time, and hospital stay -- were compared using chi-square and Mann-Whitney U tests. <br><u> Results</u>:<br> Among 166 patients, 131 (78.9%) sustained motorized and 35 (21.1%) non-motorized injuries. Helmet use was documented in 51 (30.7%). In motorized accidents, helmet use did not significantly affect the likelihood of surgery (37.8% vs. 33.7% p=0.64), severe injury (64.4% vs. 75.6%, p=0.18), or length of stay. In the non-motorized group, helmet users exhibited significantly longer operative times (mean 361 vs. 110 minutes, p=0.048), without differences in surgery rate, severe injury, or length of stay. Overall, helmet use was more frequent among motorized riders (p=0.07) but did not translate into reduced facial fracture complexity. <br> <u> Conclusion</u>:<br> Helmet use did not reduce surgical or critical care burden among patients with facial fractures. Longer operative times among helmeted cyclists may reflect forceful impact or incomplete facial coverage, highlighting the need for improved helmet engineering and facial protection standards.
