Abstract: PURPOSE: To evaluate the treatment results of mandibular symphyseal and parasymphyseal fracture combined with dislocated intracapsular condyle fractures in 28 consecutive cases. METHODS: Twenty-eight patients treated in our department during 2008 to 2013 were included in this study, in which 22 sides were treated by open reduction and the medial condylar fragments were fixed with titanium screws, while the other 22 sides underwent conservative close treatment. The treatment outcomes were followed up, evaluated and analyzed with SPSS 17.0 software package for Wilcoxon test. RESULTS: Seventeen of 22 condyle fractures were repositioned in surgery group which was much better than 4 of 22 in close treatment group (P<0.01). Functional outcomes of the patients treated with surgical treatment group were better than the close treatment group. CONCLUSIONS: The dislocated intracapsular condyle fractures should be treated by surgical reduction with the maintenance of the attachment of lateral pterygoid muscle in this kind of fracture, because it is beneficial to repositioning the condyle fractures, closing the lingual gap and maintaining the width of mandible.
