Relationship Between the Severity of Oral and Maxillofacial Injuries and Helmet Use by Type in Motorcycle Accidents Relationship Between the Severity of Oral and Maxillofacial Injuries and Helmet Use by Type in Motorcycle Accidents Yokoyama, Tomoko Kawamata, Hitoshi Hitosugi, Masahito Sasaki, Tadaaki Imai, Yutaka motorcycle accident maxillofacial injury helmet severity of injury oral surgery Helmets are known to be effective in reducing the severity of head injuries in motorcycle accidents. Although, to our knowledge, few reports have examined the relationship between the severity of oral and maxillofacial injuries and helmet use by type in motorcycle accidents. We retrospectively analyzed 54 patients with oral and maxillofacial injuries from motorcycle accidents and attempted to clarify the relationship between injury severity and the protective effects of a helmet. We studied 40 men and 14 women with a mean age of 26.1±15.0 years (range, 15 to 79 years) who sustained oral and maxillofacial injuries in motorcycle accidents treated in Dokkyo University Hospital from 1994 through 2003. In each case, we examined the mechanism of injury, type of helmet the injury severity score, the 1990 revision of the Abbreviated Injury Scale (AIS-90) score, and the length of hospitalization. Of these 54 patients, 47 patients wore a helmet. Of these 47 patients, 8 (14.8%) wore a full-face type of helmet and 39 (72.2%) wore an open-face type of helmet. The injury severity scores and the Abbreviated Iniurv Scale scores for head and neck were not significantly different by helmet use or type of helmet. However, the AIS-90 scores for facial injuries were significantly decreased with helmet use. The scores for facial injuries in the patients who wore the full-face type of helmets (1.4±0.5) were significantly lower than those in the patients who wore the open-face type of helmets (1.8 ±0.4, p<0.05) and in patients without helmets (1.9±0.4, p<0.05). Wearing a helmet effectively prevented oral and maxillofacial injuries; although, it could not fully prevent all oral and maxillofacial injuries in motorcyclists. These injuries may have been caused by indirect forces transmitted through the helmet. 原著 Original 2006-03-25 eng journal article https://dmu.repo.nii.ac.jp/records/418 AA00629581 03855023 Dokkyo journal of medical sciences 33 1 11 16 https://dmu.repo.nii.ac.jp/record/418/files/KJ00004451267.pdf application/pdf 518.3 kB 2017-05-24
