Head injuries are the main cause of disability and deaths in a motorcycle accident. The role of the helmet to reduce morbidity and mortality is already known. We sought to investigate the effectiveness to prevent head injury by different helmet types. Motorcycle accident victims who visited the study hospital from June 2012 to May 2013 were included. Data was obtained from direct interview of the patient, interview of the EMT personnel, medical records, and ambulance run-sheets. We divided patients into 4 groups by the types of helmets such as full face helmets (FFHs), open face helmets (OFHs), half coverage helmets (HCHs), unhelmeted. Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS) were analyzed to compare injury severity according to the helmet types. The patients were frequency matched by sex, age, velocity at the accident and to make the distribution of exposure to the confounding variable similar. Of 424 patients who visited the study hospital we frequency matched 49 patients in each helmet type. Lower extremity and head were the most common Injury sustained and especially head and face showed different injury frequency among 4 group. Head injury compared by AIS score was the highest in unhelmeted group followed by HCH, OFH, and FFH. In the comparison of severe head injury over AIS 2, OFH group showed 1.8 times increased rate of frequency, HCH group 2.2 times, and unhelmeted group 2.8 times than FFH group. (OR 1.790, 95% CI: 0.748-4.284, OR 2.216, 95% CI: 0.895-5.051, OR 2.7828, 95% CI: 1.155-6.442, p=0021, respectively). Of the four helmet states FFHs provided motorcyclists the most protection from head injuries.
