Introduction: Maxillofacial injures are affected by population, social and financial conditions. Increased and up-to-date knowledge about maxillofacial trauma may aid in the implementation of preventive strategies to reduce maxillofacial trauma. Aim: The objective of this research was to evaluate the prevalence, pattern, and etiology of maxillofacial trauma in patients treated at Chengalpattu Medical College and Hospital. Materials and methods: This retrospective study was conducted in the Department of Dental Surgery. Information on age and gender, etiology and mechanisms of trauma and facial bone fractures have been collected and analysed retrospectively to determine the prevalence, pattern and etiology of maxillofacial trauma. Results: This study included a total of 854 maxillofacial trauma patients. 90.3 percent of the overall trauma was attributed to maxillofacial fractures. There is a statistically significant association between gender and the etiology of study subjects with maxillofacial trauma. Fractures of the mandible (42.6 %) were significantly more frequent than malar and maxillary bone fractures (35.7%). Conclusions: It can be concluded that maxillofacial injuries occur mainly as a result of road traffic accidents with male predominance and that there is a significant association between gender and mechanisms of trauma in the prevalence of maxillofacial trauma.
