Abstract
Purpose: The mandibular angle is the most frequent site of mandibular fractures, and has the highest rate of complications. An anatomical reduction of the fracture together with functionally stable fixationis required to minimize the complications and achieve an immediate, active function. This study evaluated the genderdistribution, etiology, relationships between tooth extraction from the line of the mandibular angle fracture and the infection rate, location of the fracture, number of plates, and post-operative complications related to mandibular angle fractures.
Materials and Methods: One hundred and twenty-eight patients were enrolled in this study from 2008 to 2010.
Results: Mandibular angle fractures were more common in males and teenagers. The most common causes were assault and automobile accidents. Extractions were performed in 43 patients (33.6%), and postoperative infections occurred in 2 patients (4.6%). Eighty-five patients were in the non-extraction group, and postoperative infections occurred in 5 patients (5.9%). No significant differences were observed between the 2 groups. The mandibular angle was the only fracture in 61 cases (47.7%). The remaining cases had fractures occurring at other locations. Twenty-seven patients (21%) were treated with trocars. Of these, 2 patients suffered facial nerve damage.
Conclusion: An indication for tooth extraction may exist in cases showingmore than 2° movement, cases with periodontitis or inflammation around the root, cases with tooth caries, and cases in which the tooth impedes mandibular reduction.
