Facial fat grafts decrease in volume after transplantation. This observation is based on overall facial three-dimensional analyses, because there is sparse information on volume changes in well-defined aesthetic areas. The authors aimed to assess the overall and, more specifically, the local volumetric effects of facial fat grafting and relate these effects to patient satisfaction up to 1 year after treatment.
All consecutive adult female patients who were scheduled for facial fat grafting without additional surgical procedures were asked to participate. All patients underwent the same fat grafting method. An algorithm-based personalized aesthetic template was applied to define specific aesthetic areas on the preoperative three-dimensional image. Objective outcome parameters [i.e., three-dimensional volume differences, patient satisfaction (FACE-Q questionnaire)] were measured at baseline and at 6 weeks, 6 months, and 12 months after fat grafting.
Of 33 female patients who underwent a facial fat graft procedure, 23 patients had complete three-dimensional data and were eligible for analysis. The highest volume gain was observed 6 weeks after grafting and was followed by a gradual loss thereafter. Overall and in the zygomatic area, a substantial gain in volume was still present 1 year after grafting, whereas this effect was lost in the lip area. FACE-Q scales Satisfaction with Facial Appearance Overall and Satisfaction with Cheeks improved too, whereas scores for Lines: Lips returned to baseline levels. The improvement in FACE-Q scales was in agreement with the objective change in volume.
Gain in overall and local volumetric effects is accompanied by comparable changes in patient satisfaction.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
面部脂肪移植后体积会减少。这种观察结果基于整体面部三维分析，因为在明确的美学区域中，关于体积变化的信息很少。作者旨在评估面部脂肪移植的整体体积效应，更具体地说是局部体积效应，并将这些效应与治疗后 1 年内的患者满意度相关联。
所有连续的成年女性患者，如果计划进行面部脂肪移植而不进行其他手术，则被要求参加。所有患者均接受相同的脂肪移植方法。应用基于算法的个性化美学模板，在术前三维图像上定义特定的美学区域。在基线和脂肪移植后 6 周、6 个月和 12 个月时，测量客观的结果参数（即三维体积差异、患者满意度[FACE-Q 问卷]）。
在 33 名接受面部脂肪移植手术的女性患者中，有 23 名患者有完整的三维数据，符合分析条件。移植后 6 周观察到最大的体积增加，随后逐渐减少。总体而言，在颧骨区域，移植后 1 年仍存在显著的体积增加，而在唇部区域则失去了这种效果。FACE-Q 量表中面部外观整体满意度和脸颊满意度也有所提高，而嘴唇线条的评分则恢复到基线水平。FACE-Q 量表的改善与体积的客观变化一致。
总体和局部体积效应的增加伴随着患者满意度的相应变化。
临床问题/证据水平：治疗，IV。
