Autologous free fat graft is a widely accepted method of facial contour restoration in Parry-Romberg syndrome (PRS); however, complex and unpredictable facial anatomy can render this surgery extremely challenging. The integration of 3-dimensional (3D) technology strategies as a method to enhance surgical aesthetic outcomes has been demonstrated.A retrospective chart review was performed for PRS with autologous, free fat graft between 2016 and 2017. Based on 3D volumetric facial analysis and presurgical simulation, a 3D printed fat graft guide was produced. Surgical outcomes were analyzed by volumetric measurements of the upper, middle, and lower face segments.A total of 9 patients were included in the study. Their upper and middle facial volumes before and after the procedures showed statistically significant volume augmentation (upper face, P = 0.004; middle face, P = 0.002) 6 months postoperatively (T1). Facial asymmetry was also statistically significantly corrected (middle face P = 0.012; lower face P = 0.025) at 1 year after the procedure (T2).The advantageous application of 3D comprehensive technology for aesthetic improvements in patients with PRS with autologous, free fat graft treatment has been demonstrated. Precise preoperative planning based on simulations and postoperative 3D volumetric analyses can help adequately predict fat graft strategies.
自体游离脂肪移植是帕里-罗默伯格综合征（PRS）面部轮廓修复中一种广泛接受的方法；然而，复杂且不可预测的面部解剖结构会使该手术极具挑战性。三维（3D）技术策略作为一种提高手术美学效果的方法已得到证实。
对2016年至2017年间接受自体游离脂肪移植的PRS患者进行了回顾性病历审查。基于3D面部体积分析和术前模拟，制作了一个3D打印的脂肪移植导板。通过对上、中、下脸段的体积测量来分析手术效果。
该研究共纳入9例患者。术后6个月（T1），他们手术前后的上脸和中脸体积显示出统计学上显著的体积增加（上脸，P = 0.004；中脸，P = 0.002）。术后1年（T2），面部不对称也在统计学上得到了显著改善（中脸P = 0.012；下脸P = 0.025）。
3D综合技术在接受自体游离脂肪移植治疗的PRS患者美学改善方面的优势应用已得到证实。基于模拟的精确术前规划和术后3D体积分析有助于充分预测脂肪移植策略。
