Evaluation of fixation techniques with titanium plates and Kirschner wires in zygoma fractures. Preliminary study

This study aims to evaluate the quality of treatment of two techniques of reduction and fixation of zygoma fractures. The sample was 10 patients were divided into two groups. The experimental group received the technique of closed reduction with Kirschner wire fixation, while the control group, received the open reduction technique with titanium plate fixation. In both groups, the zygoma fractures were of the Knith and North type III, IV, and V. Furthermore, the both groups were submitted to a subjective evaluation through the patients perception, where they could evaluate the deformity regions, the paresthesia, the mouth opening, and the pain during mouth opening. During this study, we consider that t (0) is the preoperative period, while the t (1) is the postoperative. The quality assessment of the bone reduction was performed using quantifiable point measured from the tomographic images, i.e., it was used as points: the lateral orbit wall; the zygoma anteroposterior projection; the orbital globe volume; and the orbital globe projection. As results, during t (1), 70% of the patients showed paresthesia, while 20% retained the complaint of deformity. Also it was observed that the mouth opening amplitude in both groups was increased. Considering the experimental and the control group, the means of (a) the lateral orbit wall disjunction and (b) the difference of the anteroposterior zygoma projection were decreased. Regarding the orbital globe projection, it was observed a reduction in both groups. Finally, we concluded that both techniques achieved a good reduction of zygoma fractures in postoperative period.
