title: Rigid internal fixation of mandibular fractures--an analysis of 45 patients treated according to the ASIF method.
abstract: A report is given of 45 patients with fractures of the mandible treated by the method of rigid internal fixation. In a majority of cases, there were either absolute or relative contraindications for an IMF. Most of the fractures plated were body fractures of the mandible, followed by angular, and symphysis fractures. In 4 cases, the fractures, caused by gunshots, were compound ones. In these, extensive soft tissue reconstructions were also performed. In a majority of the patients, good primary healing was observed, and the mean hospitalization time was only 4.4 days. The infection rate of 13% was, however, relatively high, and a few disturbances were seen with respect to motor and sensory function of the lower lip. Slight occlusal dysharmonies were registered in 23%, on an average of 22 weeks postoperatively, but these could be adjusted with a minimum of grinding. It was concluded that bone plating is a useful method in the treatment of several different types of mandibular fractures including the severe compound ones. The method can be especially recommended in cases in which an IMF is contraindicated or should be avoided. The possibilities for decreasing the frequency of postoperative infections are discussed.
