Big Data Analysis of Facial Fracture Epidemiology in South Korea From 2015 to 2020: Impacts of Aging and Personal Mobility

The epidemiology of facial fractures is continuously evolving due to various influencing factors, including social, economic, and technological advancements. Thus, an updated analysis of facial bone fractures is necessary. This study aimed to provide an updated epidemiological analysis of facial bone fractures and assess severity using multiple factors. We retrospectively reviewed patients who underwent facial bone fracture surgery at 3 teaching hospitals in South Korea between January 2015 and December 2020. Data collected included patient demographics (sex and age), trauma mechanism, alcohol intoxication status, and fracture types. Trauma mechanisms were categorized into 7 groups: assault, fall, sports, occupational injury, motor vehicle crash, bicycle, and personal mobility. Severity was assessed using the modified facial injury severity scale. A total of 5953 patients (4437 males and 1516 females) were included, with ages ranging from 1 to 92 years (mean age: 36.37±18.61 y). A steady decline in the number of patients was observed from 2015 to 2020. Falls were the most common cause of facial fractures (2300 cases, 39%), and nasal bone fractures were the most frequent type (3683 cases, 46%). The number of elderly patients (> 60 y) and injuries caused by personal mobility devices increased steadily. Male sex and alcohol intoxication were associated with higher severity scores. Motor vehicle crashes had the highest severity scores (2.246). While the incidence of facial bone fractures has decreased in recent years, the proportion of elderly patients and injuries caused by personal mobility devices is increasing, posing a significant burden on the health care system.
