Purpose: An intraoral approach is effective in treating mandible fractures without complications, such as extraoral scar formation and damage to the mandibular branch of the facial nerve. The aim of this study was to report possible complications as well as their incidence rates after open reduction and internal fixation using 2.0 mm monocortical miniplate fixation to treat mandible fractures via an intraoral approach. Materials and Methods: The subjects were selected from patients who visited Chosun University Dental Hospital with mandible fractures as their chief complaint, and they underwent open reduction and internal fixation with a 2.0 mm miniplate through an intraoral approach from 2010 to 2012. Results: A total of 101 patients and 169 miniplates were included. The period of intermaxillary fixation varied from zero to more than 2 weeks. Intermaxillary fixation was performed for more than 2 weeks in five patients, accompanied by a subcondylar fracture. Seven patients in total, representing a notably low rate, experienced complications such as irritation, nerve damage, infection, screw loosening, and malocclusion. Conclusion: Open reduction and internal fixation with a 2.0 mm monocortical miniplate via an intraoral approach is a valuable method for treating mandible fractures and exhibits a low rate of complications as well as high stability.
