Abstract
Fractures of the zygomaticomaxillary complex are among the most common face traumas. Based upon the complexity and great variety of reported diagnoses and treatments, the proposal of this study was to evaluate, clinically and radiographically, unilateral zygomatic fractures treated through internal rigid fixation with miniplates and screws of 1.5 mm. Material and Method: 15 patients with unilateral fractures of the zygomaticomaxillary complex were analyzed, and compared with 15 patients without fractures so that a comparative analysis of the area and the perimeter of the orbital cavities could be made, as well as the distance from the nasal point to the zygomatic prominence between both groups. Results: In the radiographic analysis, the both groups presented similarity in the perimeter and in the area of the orbital cavities. Concerning the distance from the nasal point to the zygomatic prominence, only the operated group showed a significant difference between the sides, even though clinically the observation of the asymmetry had been absent or discreet. Conclusion: The treatment of unilateral fractures of the zygomaticomaxillary complex with the use of plates and screws of the 1.5 mm system proved to be effective, showing good esthetic results and low complication rates.
Highlights
The treatment of the fractures of the zygomaticomaxillary complex (ZMC) is amply discussed in the literature, being that three great conflicts still persist in relation to the applied therapy [1]
The second is related to the necessity to fix them or not after the reduction, and the third concerns the number of fixation points necessary so that the fractures of the ZMC are stabilized [2]
Considering the high rate of fractures in the ZMC and the disagreements about treatment we proposed to carry out the present study to evaluating the zygomatic fractures treated with a 1.5 mm fixation system
Summary
The treatment of the fractures of the zygomaticomaxillary complex (ZMC) is amply discussed in the literature, being that three great conflicts still persist in relation to the applied therapy [1]. The first concerns the best way for surgical reduction of the fractures. The second is related to the necessity to fix them or not after the reduction, and the third concerns the number of fixation points necessary so that the fractures of the ZMC are stabilized [2]. Technological development together with surgical necessity stimulated the development of extremely delicate systems of plates and screws with guarantees of promoting adequate resistance to bending and three-dimensional mechanical stability assuring predictability in the treatment of facial fractures [4,5,6].
