“…In our study, immediate postoperative MDCT scanning was preformed immediately at 2 month follow up to evaluate quality of reduction and quantitative analysis of facial symmetry. This was in accordance with Gaziri et al (24) study who compared immediate postoperative CT scans with those obtained after 5 weeks and found that no relevant displacement occurred when adequate fixation was provided. In the same time this was in contrast with Khaqani et al (15) study who reported that immediate postoperative CT scanning was probably sufficient for the assessment of malar bone reduction adequacy.…”

“…In addition, perceiving facial changes accurately is difficult due to the lack of information on patient's face before the injury. Gaziri et al7 evaluated asymmetry of the hard tissue after ZMC fracture by comparing the affected with the unaffected side. Patients often complain of soft tissue asymmetry when comparing with the contralateral side of the face even when bone fragments were accurately reduced.…”

ObjectivesIn this study, we assessed soft tissue asymmetry that occurred after open reduction of unilateral zygomaticomaxillary complex (ZMC) fractures. We proposed a simple method to assess soft tissue asymmetry after reduction surgery by evaluating the symmetry between the affected and the unaffected sides. The factors affecting soft tissue contour after surgery were also analyzed.Materials and MethodsSubjects included patients admitted to Wonkwang University Dental Hospital from 2008 to 2013. Cone-beam computed tomography (CBCT) images of asymmetric patients who underwent open reduction at least 3 months prior were compared with healthy patients.ResultsThe degree of asymmetry was measured in both the open reduction and control groups. Landmarks that showed a statistically significant difference between the two groups were zygion (1.73±0.24 mm), bucclae (1.08±0.26 mm), point of cheek (2.05±0.33 mm) and frontozygomatic point (1.30±0.31 mm).ConclusionWhen compared with the normal group, asymmetry can occur in the affected side, which usually shows depression of overlying soft tissue and is statistically significantly different. Evaluation of soft tissue asymmetry with CBCT images after open reduction of ZMC fracture is useful.

“…In this context, ZMC reduction poses a continuing challenge for maxillofacial surgeons because of its significant position in facial esthetics and symmetry, requiring skills and expertise. Numerous studies have demonstrated quantitative and qualitative evaluations of the adequacy of facial symmetry recovery after ZMC fracture reduction surgery [2,[11][12][13]. However, there are few quantitative studies on postoperative symmetry recovery after ZMC reduction in East Asian populations with characteristic zygoma shapes.…”

Background:The zygomaticomaxillary complex (ZMC) has a protruded, convex shape and plays a vital role in determining the contour by affecting the width of the middle face. This study aimed to evaluate the efficiency of ZMC fracture reduction and explore detailed directions for outcome improvement. Methods: We conducted a retrospective study of patients diagnosed with unilateral ZMC fracture who underwent ZMC reduction surgery at a single hospital between January 2015 and May 2020. The primary outcome variable was facial asymmetry using the difference in the bilateral malar eminence (ME) position measured by computed tomography scan. The 3-dimensional distance (IA, asymmetry index) and the distance in each dimension, Dx (anteroposterior distance), Dy (mediolateral distance), and Dz (superoinferior distance) were compared. Results: A total of 101 patients with ZMC fractures and 54 non-fracture patients were enrolled in the study. The mean age of the study sample was 43.49 years (control sample, 43.35 years), and the male-to-female ratio was 66.3:33.7 (control sample, 64.8:35.2). There were 53 and 48 patients with right and left ZMC fractures, respectively. The IA was not statistically different between the two groups. In terms of position in each dimension, only Dx was significantly different between the two groups. Conclusion:The results show that overall facial asymmetry was recovered after ZMC reduction, but in certain dimension significant difference in ME position has still remained. For further improvement, treatment should be performed to relieve malar depression in the anteroposterior dimension.
