Helmet shielding effect in mandibular fractures during road traffic accident.

OBJECTIVE

The objectives of this study are to evaluate the proportion of helmeted and nonhelmeted patients sustaining mandibular fractures.

MATERIALS AND METHODS

A retrospective study was conducted on 200 patients reporting to oral and maxillofacial surgery (OMFS) unit, trauma center, and department of OMFS. A predesigned questionnaire was used to collect the necessary data. Patients were evaluated for age, gender, mode of transport (2/4 wheeler), presence of safety measure at the time of accident (helmet/seatbelt), maxillofacial injury in two wheeler (with helmet and without helmet), type of impact, and its association to maxillofacial fractures, particularly site of maxillofacial fractures. The association between mode of injury, presence of safety measures, impact type, and site of maxillofacial injuries was assessed using the Chi-square test. < 0.5 was considered statistically significant.

RESULTS

The mean age of patients was 30 years, and approximately 92.5% of accidents patients were male. In this study, 35% nonhelmeted riders were reported head injury and 5% of the helmeted rider reported head injury. 54.5% of the patients suffered frontal impact, 28% collision, and 17.5% lateral slide collision. Head injuries are the main cause of death among the riders of all two wheelers. Lateral sliding collision injuries (17.5%) resulted 60.6% of the fractures mandible, 24.2% midface injury, and associated injury (15.15%).

CONCLUSION

The use of helmet is strongly recommended to prevent head injuries and facial injuries. In the nonhelmeted riders in motorcycle accidents, the incidence of mandible fractures increases proportionally.
