    Abstract:
    The question whether- and if by which means-operative reconstruction of condylar process fractures is appropriate is still unresolved. This study was initiated to compare osteosynthesis of low dislocated and/or luxated condylar fractures by means of miniplates or lag screws according to Eckelt. 22 patients participated, 16 being treated with miniplate osteosynthesis, 6 with lag screws. Investigation concentrated on the parameters TMJ-function (side shift in dynamic and static occlusion, maximum interincisal distance, impairment of pro- and laterotrusion), radiologic post-operative fragment position, intra- and postoperative complications, and evaluation by the patients. Miniplate osteosynthesis showed better results leading in 80% to an unimpaired TMJ function compared to 50% of the lag screw group. Miniplate osteosynthesis was performed faster. No intra- or postoperative problems occurred in contrary to the lag screw, where one fracture of the screw intra- and one post-operatively were noted. Even if the numbers are too small for statistical calculations, trends are shown favouring miniplate osteosynthesis for operative reconstruction of condylar fractures.
