Introduction: In open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. This study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    Materials and Methods: Access to the fractures was via an extraoral approach (through existing scars or incisions). After reductions of mandibular fractures, the fracture line fixation was accomplished using two mini-plates perpendicular to each other. One-week intermaxillary fixation (IMF) was applied and ۳ weeks of soft diet was recommended in the post-operative period. All patients were followed up for at least ۱ year regarding infection and malocclusion.   Results: Twenty-five patients (۲۸ fracture lines) underwent this technique. Most (۸۱.۸%) patients were male and the mean age was ۴۱.۳±۷.۵۹ years (range, ۱۷–۷۳ years). Symphyseal fracture (frequency, ۵۲%) was the most prevalent followed by angle (۳۲%) and body (۱۶%) fractures. Among the patients who underwent surgery, only one malocclusion and no cases of infection were observed. No cases [Rachel۱] of facial nerve weakness or damage were observed in this study.   Conclusion:  This method can be used in specific cases to replace treatment with one mini-plate, which necessitates a more intensive fixation or reconstruction plate therapy.      [Rachel۱]Please confirm
