BackgroundMaxillomandibular fixation (MMF) is an important tool in the treatment of facial fractures and bone-anchored arch bar systems have emerged as treatment options. This study illustrates our experience with the Synthes MatrixWAVE MMF system and the novel application in closed treatment of patients with multiple concurrent mandibular fractures.MethodsWe enrolled eight patients with concurrent mandibular fractures and treated them with the Matrix Wave MMF system. The malleable arch bars were fitted and then secured using 6 to 8mm screws. The arch bar was and either stretched or compressed to ensure optimal positioning. 24-gauge interdental fixation wiring was placed using the fish loop technique on either side of the fracture to achieve stabilization of the mandible fractures.ResultsAll eight patients were retained in MMF until stable occlusion was achieved with clinical evidence of healing, approximately 4 to 6 weeks. Post-operative Panorex scans did not reveal any evidence of damage to tooth roots. None of the screws became overly embedded in the mucosa secondary to overgrowth; the arch bars were successfully removed in an outpatient setting without local anesthesia.ConclusionsThe Synthes MatrixWAVE MMF system has unique features such as prominent screw anchor heads and horizontal malleability unique from other bone anchored arch bars. These features allow for completely closed treatment of patients with multiple concurrent mandible fractures.
