Mandibular Ramus Fracture: An Overview of Rare Anatomical Subsite

Aim. The present study aims at exemplifying the incidence, and aetiology and analyses the outcomes of open reduction internal fixation (ORIF) over closed treatment of mandibular ramus fractures. Patients and Method. In the present retrospective analysis of mandibular fracture patients, variables analysed were age, sex, cause of injury, pretreatment occlusion, treatment given, period of maxillo-mandibular fixation (MMF), and posttreatment occlusion. Results. Out of 388 mandibular fractures treated, ramus fractures were 12 (3.09%). In the present study, predominant cause of mandibular ramus fracture was road traffic accident (RTA) n = 07 (58.33%) followed by fall n = 04 (33.33%) and assault n = 1 (8.33%). The average age was 35.9 years with a male predilection. Of these, 9 patients were treated with ORIF while remaining 3 with closed treatment. The average MMF after closed treatment was 21 days and 3 to 5 days after ORIF. There was improvement in occlusion in all 12 patients posttreatment with no major complication except for reduced mouth opening in cases treated with ORIF which recovered with physiotherapy and muscle relaxants. Conclusion. Mandibular ramus fractures accounted for 3.09% with RTA as a common aetiology. ORIF of ramus fractures facilitated adequate functional and anatomic reduction with early return of function.
