NCT06717009
A Study of 3D Visualization Techniques to Improve the Quality and Safety of Robot-assisted Nephron Sparing Surgery for Complex Renal Tumors.
The goal of this clinical trial is to learn the evidence-based medical value of 3D visualization techniques to improve tumor control, preservation of renal function, and perioperative safety in robot-assisted nephron sparing surgery for complex renal tumors. The main question it aims to answer is: Is 3D visualization techniques more effective in improving robot-assisted nephron sparing surgery for complex renal tumors in terms of tumor control, renal function preservation, and perioperative safety. The researchers will randomize participants into a 3D trial group and a conventional group for comparison. Participants will: Complete Blood routine, liver and kidney function tests on the first and third day after operation. Have Renography at 3 and 12 months after the operation. Cooperate with follow-up visits.

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