Abstract

This study evaluated the efficacy and clinical results in patients treated for fractures of mandibular angle with single non-compression miniplate. One hundred and two patients with mandibular angle fractures were treated by open reduction and internal fixation using single non-compression 2.0 mm miniplate and screws through transoral incision. Clinical and radiological examinations were undertaken during follow-up period. Six patients(6%) experienced complications and required secondary surgical intervention; 3 cases of screw loosening, 2 cases of plate fracture and 1 case of infection. 5 cases were treated with plate remove and healed uneventually and one patient who had plate fracture was treated with maxillomandibular fixation without surgical intervention. However, these complications were minor, so we could treat these patients in the office without hospitalization. None of these patients had additional complications after secondary interventions. The use of single non-compression miniplate for treatment of mandibular angle fractures is a simple, reliable technique and we could manage small number of complications in the outpatient setting.
