目的 探讨利用CT断层扫描成像技术定量分析面部脂肪移植成活率的可行性。
方法 自2015年12月至2016年3月,对8例行面部脂肪填充的患者在术前、术后4周、术后12周时进行面部CT扫描,测量每个断层脂肪移植灰度面积(ROI)并进行统计分析,计算脂肪成活相对值。
结果 CT断层扫描成像能清楚显示面部填充部位的脂肪层次。术前、术后4周、12周的脂肪移植区域ROI分别为(4.61±1.32)、(9.17±2.01)和(7.60±1.47)。统计结果显示,术后12周和术后4周的ROI均显著高于术前ROI(P<0.05),但术后12周和术后4周ROI无显著差异(P>0.05)。与术后4周相比,术后12周移植脂肪成活相对值为(65.57%±10.27%)。
结论 CT断层扫描成像技术可以用于定量分析面部脂肪移植的成活率。

Objective To explore the feasibility of quantitative analysis of survival rate of facial fat graft by CT tomography.
Methods From December 2015 to March 2016, 8 patients who underwent facial fat filling were included in the study. Facial CT scan was performed before, 4 weeks and 12 weeks after surgery, respectively. Then the area of grafted fat tissue (regions of interest, ROI) was measured and statistically analyzed, and relative value of fat survival was calculated.
Results CT tomography imaging can clearly show the level of fat in the filling area of the face. The ROI of fat transplantation area before, 4 weeks and 12 weeks after surgery was 4.61±1.32, 9.17±2.01 and 7.60±1.47, respectively. Statistical result showed that ROI at 12 weeks and 4 weeks after surgery were both significantly higher than that before surgery (P<0.05), but ROI at 12 weeks and 4 weeks after surgery showed no significant difference (P>0.05). Compared with 4 weeks after surgery, the survival value of transplanted fat at 12 weeks after surgery was 65.57%±10.27%.
Conclusion The technique of CT tomography imaging can be used as a method of quantitative analysis for survival rate of facial fat graft.
