Abstract

Purpose

Reduction malarplasty (RM) is a common facial contouring aesthetic procedure in East Asia. However, there is a lack of data on the postoperative changes in soft tissue and patient-reported outcomes. This retrospective study aimed to evaluate the soft-tissue changes and surgical outcomes following L-shaped RM.

Methods

Fifty-five patients who underwent L-shaped RM were enrolled and 55 patients who underwent genioplasty were enrolled as controls. The soft-tissue changes in relation to the underlying skeletal tissue were analyzed using computed tomography (CT) and three-dimensional (3D) stereophotogrammetry images. Patient’s satisfaction and surgical outcomes were investigated using the FACE-Q and Wrinkle Severity Rating Scale (WSRS).

Results

In the RM group, the soft tissue in zygoma (S2), zygomatic arch (S3), and upper cheek (S5) regions showed a significant inward reduction postoperatively (p<0.001), while the paranasal region (S4) showed a significant outward augmentation (p<0.001). Compared with the control group, the postoperative soft-tissue changes in S2, S3, S4, and S5 demonstrated significant differences in the RM group (p<0.001). The postoperative skeletal-tissue changes in the upper zygoma (B2), zygomatic arch (B3), and lower zygoma (B5) regions exhibited a significant decrease (p<0.001). Significant correlation was observed between the soft and hard tissue changes in B2, B3, and B5 regions (p<0.001). Additionally, patients demonstrated significant postoperative improvement in satisfaction with appearance, although 6 patients’ WSRS grade increased by one-grade.

Conclusion

Following RM, the soft tissue in surgical regions showed inward depression, while the paranasal soft tissue protruded outward, indicating that the soft tissue exhibited a certain degree of sagging. Although the severity of nasolabial folds increased in some patients, the patient’s self-evaluation of aesthetics remained unaffected. The findings suggest that surgeons should consider skeletal and soft-tissue changes when planning RM, and patients should also be informed about the potential postoperative soft-tissue changes to effectively manage their expectations.

l型复位颧成形术后三维面部软组织改变：一项前瞻性回顾性研究

目的在东亚地区，整形术是一种常见的面部整形手术。然而，缺乏关于术后软组织变化和患者报告结果的数据。本回顾性研究旨在评估l型RM术后的软组织变化和手术结果。方法55例行l型肾移植的患者和55例行genplasty的患者作为对照。使用计算机断层扫描（CT）和三维立体摄影测量图像分析软组织相对于底层骨组织的变化。采用FACE-Q和皱纹严重程度评定量表（WSRS）调查患者满意度和手术结果。结果RM组颧骨区（S2）、颧弓区（S3）、上颊区（S5）软组织术后明显向内缩小（p < 0.001），鼻副区（s < S4）明显向外增大（p < 0.001）。与对照组相比，RM组术后S2、S3、S4、S5的软组织变化具有显著性差异（p<0.001）。术后上颧骨（B2）、颧弓（B3）和下颧骨（B5）区域的骨组织变化明显减少（p<0.001）。B2、B3和B5区软硬组织变化之间存在显著相关性（p<0.001）。此外，患者术后对外观的满意度有显著改善，尽管6例患者的WSRS评分增加了1级。结论RM术后手术区软组织向内凹陷，鼻旁软组织向外突出，软组织有一定程度的下垂。虽然部分患者鼻唇皱襞的严重程度有所增加，但患者对美学的自我评价并未受到影响。研究结果表明，外科医生在计划RM时应考虑骨骼和软组织的变化，患者也应了解潜在的术后软组织变化，以有效地管理他们的期望。
