“…In addition, fixation at a higher level of the medial part of the malar complex can provide more favorable outcomes by reducing the external rotational force from the masseter muscle based on previous study which included old-cadaver samples with no clinical data. 22,23 Lee et al 6 reported that for superior repositioning, the amount of setback is more important than the amount of bony resection. However, in maxillofacial surgeries, setback can cause soft tissue ptosis.…”

“…Therefore, rigid fixation for superiorization of malar arch offers a practical solution to prevent the likelihood of cheek ptosis after reduction malarplasty. In addition, fixation at a higher level of the medial part of the malar complex can provide more favorable outcomes by reducing the external rotational force from the masseter muscle based on previous study which included old-cadaver samples with no clinical data 22,23 .

Background: Reduction malarplasty has been popular among Asians with a wide facial width. In general, malar setback after bony resection is regarded as the standard objective of reduction malarplasty. However, unnecessary bony resection may lead to various postoperative complications. Therefore, we suggest the use of reduction malarplasty without bony resection to achieve a similar narrowing effect of the facial width, based on radiographic analysis of malar arch movement. Patients and Methods: This retrospective study analyzed 48 patients with a wide midface who underwent reduction malarplasty between September 2018 and December 2019. We included 40 cases of advancement repositioning malarplasty (AR) without bony resection and 8 cases of setback reduction malarplasty (SR) with bony resection. The three-dimensional position of the malar arch expressed by coordinates (x, y, and z) on threedimensional computed tomography scans was used to compare the positional change between the surgical methods. The paired t-test, Wilcoxon text, and independent t-test were used in data analysis, and statistical analysis was performed using SPSS 23.0 software. Results: Medial and superior movement of the freed malar arch segment was significantly different between AR and SR (P < 0.05). Although medialization and superiorization were not significantly different between AR and SR, there was a significant difference in anterior-posterior movement between AR and SR (P < 0.05). Conclusion:The radiologic analysis based on malar arch movement between AR and SR showed similar narrowing effects on medialization and superiorization of the malar arch regardless of bony resection. Therefore, the AR can be effectively applied in case of arch dominant type or malar asymmetry. In addition, further comprehensive study including analysis on movement of facial soft tissue following malar bony movement is expected based on this study in near future.
