Simple open reduction of mandibular angle fracture using the champy's osteosynthesis line

ABSTRACT

Mandibular angle fracture causes facial aesthetic problem and functional derangement of mastication. For the open reduction of the mandibular angle fracture, various methods have been developed according to the approaching route, fixation material, fixation position and the fixation number. There remains controversis in managing the mandibular angle fracture. We treated the mandibular angle fracture using non-compressive miniplate along the Champy's ideal osteosynthesis line. For accurate reduction of mandibular angle fracture and maintain centric relation, one or two K-wires were inserted to the inferior border of both fracture segments and both fracture segments and both segments were approximated by manual force or rubber bandage. Maintaining the anatomical reduction of fracture site, fixation was done on vestibular flat area aling the medial side of extermal oblique ridge defined as Champy's osteosynthesis line with one malleable non-compression 4-hole miniplate and screws. After the fixation of plate, K-wires and rubber bandaging for intermaxillary fixation were removed. With maintaining the arch bar, exercise and soft diet were encouraged at the first postoperative day. Through the above procedure, we have experienced satisfactory osteosynthesis and good occlusion. This method has the advantages like that easy and minimal dissection, no external visible scar, no nerve damage and providing simple and ideal osteosynthesis. We present cases of mandibular angle fractures with the review of the literature.
