3D Facial Scanning for Evaluating Autologous Fat Grafting in Craniofacial Deformities

Condition(s) studied

Investigational drug(s) / intervention(s)

3dMD technology: By taking photos using 3dMD, we obtained preoperative, immediate postoperative, and long-term postoperative three-dimensional data of patients. The software automatically fused the data to obtain the volume difference of facial volume at different time points, and then divided it to obtain the objective data of facial volume improvement rate. To improve the reliability of the measurements, two researchers measured independently and took the average value.

Study summary

Treatment of craniofacial deformities is a significant topic in oral and maxillofacial surgery, and autologous fat grafting has become one of the main methods for treating facial concave deformities. However, the instability of its treatment effect has always been a bottleneck in this field, mainly due to the uncertain absorption rate of transplanted fat. This project aims to use advanced the 3dMD face system (3dMD) (3dMD Inc, Atlanta, Ga) technology to precisely measure the facial volume changes before and after autologous fat grafting to address this issue. By performing autologous fat grafting surgery on 100 patients with craniofacial deformities that meet the research criteria, 3dMD technology will be used for facial three-dimensional scanning preoperatively, immediately postoperatively, and at six months postoperatively to obtain facial volume data. Then, through precise data analysis, we will calculate the fat absorption rate and study the effects of individual factors on treatment outcomes through correlation regression analysis.

Eligibility

Primary outcome measure(s)

• Fat Retention Rate — 4 weeks postoperative and 1 year postoperative.
  Using 3dMD technology, facial profiles were captured preoperatively and postoperatively. The postoperative profiles were matched with the preoperative ones and processed using Boolean operations to obtain the volume difference, which represents the volume of grafted fat. The fat retention rate was calculated by dividing the volume of grafted fat obtained at 1 year postoperatively by the volume obtained at 1 month postoperatively.
