Abstract
To evaluate the complications and factors associated with titanium plates in mandibular reconstruction with different methods. A retrospective analysis of 660 patients who received primary reconstruction of the mandible was conducted. The characters of the mandibular defect and methods of reconstruction were recorded. The complications and factors associated with the reconstruction were analyzed. The majority of mandibular defect was in a shape of L (n = 324 ). The total complication rate was 14.7% (97/660), which included screw loosening 5.8% (38/660), plate fracture 3.3% (22/660), plate exposure 3.8% (25/660), infection 7.4% (49/660) and malunion or ununion 2.9% (19/660). The mandibular defects reconstructed by reconstructive plates had a higher complication rate than that by bone grafts. The complication rate was 10.8% (63/586) in cases reconstructed by bone grafts with miniplates. The complications were associated with radiation therapy and diabetes. Radiation therapy had a significant effect on plate exposure. Reconstruction with bone grafts can minimize the rate of plate related complication. The complications were associated with radiation therapy and diabetes.
