Aim:- The aim of this study was to analyze the pattern of mandible fracture in the region of lower Himalayas of state of Himachal Pradesh based on the mechanism of injury. Material & Method:-The records of the patients treated for their mandibular fracture were reviewed between time periods from august 2017 to December 2018. Age, Gender, Etiology, Anatomical site of mandible, multiple fractures within the mandible and Method of treatment were recorded and assessed. Result: Maximum incidence of fractures was observed among the individuals in 3rd decade (29.55%) followed by 4th decades (27.28%) of life. Male to female ratio was 10:1 suggestive of male predominance. Road traffic accidents (RTAs) were observed to be the predominant etiological factor responsible accounting for 40.90% of the total injuries followed by fall (39.77%) which is almost equal to RTAs, interpersonal violence (11.37%),sports injury (3.4%) animal injury (2.28%). Condyle exhibited the highest incidence (33.8%) amongst the anatomic sites, followed by parasymphysis (22.55%), angle (17.29%), body (13.55%), symphysis (7.52%), Dentoalveolar (3.75%), coronoid (1.5%) and ramus (0.76%). Single fracture site was noted in 56.82% cases followed by two anatomical sites in 35.23% then three anatomical sites in 7.95% cases. Fracture mandible mainly treated with open reduction and internal fixation in 73.87% of cases. Conclusion: High incidence of mandible was observed with male predominance in 3rd decade of life, RTAs and fall being the chief cause and the condyle was the most commonly involved site. Mandible can fracture at single, double or multiple sites. Mandible fracture can be treated mainly by open reduction with internal fixation with miniplates.
