Background: To evaluate the cases of mandible fractures treated by open reduction and rigid fixation at the B.J Medical college, Ahmedabad. Methods: Two hundred and forty mandible fractures cases were treated by open reduction and rigid fixation from September 2011 to September 2017. These were retrospectively analyzed based on the following patient related factors i.e. mode of injury, age and sex distribution, site of injury, associated injuries and surgical treatment. Result: The significant finding was that the most common etiology for fracture mandible was road traffic accidents (RTA), 216 (90%). Of the patients who reported, 205 (85.5%) were males in the third decade of life. 108 (45%) patients had parasymphysis fractures, 74 (30.5%) had angle fractures, 36 (15%) condylar fractures, 19 (7.9%) body fractures and 3 (1.6%) had ramus fracture. Early intervention using open reduction and internal fixation was the protocol followed, based on which results were studied. Conclusion: As RTA especially two wheelers accidents appeared to be the most common cause of mandible fractures. Most commonly males suffer mandible fracture. Moreover open reduction and rigid internal fixation appears to be the suitable treatment modality in successful treatment of mandible fractures in reducing morbidity and complications and ensuring early return to normalcy.
