Superior border versus inferior border fixation in displaced mandibular angle fractures: prospective randomized comparative study

Abstract A prospective randomized comparative study was conducted to compare open reduction and internal fixation of displaced fractures (>2 mm) via intraoral approach with application of a single monocortical miniplate according to Champy's ideal line of osteosynthesis (group A) versus an extraoral approach with application of an inferior border plate with at least two holes (bicortical screws) on either side of the fracture line (group B). Clinical and radiographic assessment was done preoperatively, immediately postoperative, and at 1, 4, and 12 weeks of follow-up. Parametric and non-parametric data were evaluated by independent samples t -test and χ 2 analysis, respectively; P
