Abstract：
BACKGROUND: The increasing number of fatalities caused by gluteal fat grafting is concerning; thus, there is a need to determine ways to obtain the ideal aesthetic effect while ensuring a safe operation. In this study, three-dimensional (3D) measurements combined with B-ultrasound were used to evaluate the effect of gluteal fat augmentation in Asians, whose safety and effectiveness were confirmed using quantitative data.
METHODS: Thirty-five consecutive female patients were evaluated in this prospective clinical study. All patients underwent B-ultrasound-assisted gluteal fat augmentation on the subcutaneous plane alone. 3D imaging and B-ultrasound analysis of the adipose tissue thickness in the gluteal region were performed preoperatively and at 1 week, 3 months and 6 months post-operatively.
RESULTS: The waist circumference of the patients decreased, gluteal circumference and length of the gluteal crease increased and average waist-to-hip ratio improved from 0.78 to 0.74. At 3 months and 6 months post-operatively, the adipose tissue thickness decreased by 5.1% and 15.1%, respectively. The fat retention rates calculated using 3D imaging measurements at 3 months and 6 months post-operatively were 77.9% and 64.7%, respectively. According to the BODY-Q scale scores, patients reported a high level of satisfaction post-operatively.
CONCLUSIONS: B-ultrasound guidance can effectively prevent the occurrence of fatal fat embolism during gluteal fat grafting and maximise the augmentation effect. The quantitative data obtained using 3D measurements and B-ultrasound confirmed the safety and effectiveness of fat injections for gluteal augmentation under B-ultrasound guidance.

摘要：
背景：臀脂移植引起的死亡人数越来越多，因此，需要确定在确保安全操作的同时获得理想美学效果的方法。在这项研究中,采用三维测量结合B超来评价亚洲人臀部脂肪增加的效果,其安全性和有效性通过定量数据得到证实。
方法：在这项前瞻性临床研究中评估了35例连续的女性患者。所有患者均单独在皮下平面进行B超辅助臀肌脂肪增加。术前及术后1周进行臀区脂肪组织厚度的三维成像和B超分析,术后3个月和6个月。
结果：患者腰围下降，臀围和臀围的长度增加，平均腰臀比从0.78提高到0.74。术后3个月和6个月，脂肪组织厚度分别下降5.1%和15.1%,分别。术后3个月和6个月使用3D成像测量计算的脂肪保留率分别为77.9％和64.7％，分别。根据BODY-Q量表得分，患者报告术后满意度较高.
结论：B超引导可有效预防臀脂移植过程中致命性脂肪栓塞的发生，最大限度地提高强化效果。使用3D测量和B超获得的定量数据证实了在B超引导下注射脂肪用于臀围增大的安全性和有效性。
