单次自体脂肪移植修复对进行性单侧面萎缩症面部体积保持率的影响

Changes of facial volume maintenance rate after single autologous fat grafted for repaired progressive facial hemiatrophy

目的探讨单次自体脂肪移植修复对进行性单侧面萎缩症面部体积保持率的影响。方法2014年1月至2015年12月,对中国医学科学院北京协和医学院整形外科医院整形五科10例进行性单侧面萎缩症患者术前使用三维扫描仪对进行面部数据采集,用Mimics 17.0软件重建患者面部三维模型,计算面部组织缺损量,用自体脂肪颗粒注射移植进行面部畸形修复,分别于术后3个月、6个月测算面部体积保持率。结果10例进行性单侧面萎缩症畸形患者均进行面部三维数据采集和自体脂肪颗粒注射移植,面部形态得到显著改善,测面部术后3个月体积保持率(35.80±3.44)%,术后6个月体积保持率(27.82±3.80)%。结论单次自体脂肪注射移植修复半侧颜面萎缩畸形术后6个月面部体积保持率低于术后3个月。

Objective To measure the change of facial volume maintenance rate after autologous fat grafted for repaired progressive facial hemiatrophy by using three-dimensional digital technology. Methods 3D scanner was used to acquire facial data in 10 patients with progressive facial hemiatrophy before operation;Mimics 17.0 software was used to reconstruce patients' facial 3D model and to calculate the volume of facial tissue defect;autologous fat was grafted to repair facial deformity. The facial volume maintenance rate was calculated in all the patients 3 months and 6 months after operation. Results We had performed facial 3D data acquisition and facial repaired with autologus fat grafted in 10 patients;patients' facial morphology was improved. The mean facial volume maintenance rate was (35.80±3.44)% in 3 months and (27.82±3.80)% 6 months after surgery. Conclusions The mean facial volume maintenance rate in postoperative 3 months is inferior to that in 6 months in single autologous fat grafted for repairing progressive facial hemiatrophy.
