[Evaluation of the postoperative clinical results of repositioning isolated zygomatic fractures].
This retrospective study included 148 patients who were evaluated for postoperative long-term results after osteosynthesis of isolated zygoma fractures. The influence of open reposition of the zygomaticoalveolar crest to middle face symmetry was evaluated quantitatively with a zygometer. In dependence on operative management patients were divided into two groups: In group I zygomaticofrontal suture (1-point-fixation) and infra-orbital rim were exposed (2-point-fixation), followed by osteosynthesis. In group II additional exposure of zygomaticoalveolar crest was performed and if required osteosynthesis was performed (3-point-fixation). For osteosynthetic reconstruction of isolated zygoma fractures the only 2-point-fixation is usually enough to achieve lateral middle face symmetry. In all cases zygomaticofrontal suture and alternatively infra-orbital rim or respectively zygomaticoalveolar crest should be supplied osteosynthetically. A further 3-point-fixation is indicated only in exceptional cases--for example comminuted fractures of lateral middle face columns. For an exact anatomical reposition of zygoma fractures the exposition and possible osteosynthesis of zygomaticoalveolar crest is recommended.
