Abstract:
Objective:The purpose of this study is to establish the trajectory of targeted grafting for facial fat compartment based on anatomical research, and then bring it to clinical practice.Methods:The boundary of fat compartment and the relationship of adjacent vessel and nerve were clarified through autopsy. The recommended injection points and trajectory for targeted fat grafting were established on the anatomical findings. Retrospective clinical data of facial rejuvenation of 46 patients through targeted fat grafting were collected from June 2017 to June 2019 in Shanghai Ninth People’s Hospital. The result of 3D scanning were analyzed to evaluate the survival rate of fat grafts.Results:There were subcutaneous superficial fat compartments in the frontal region, and there were both deep and superficial fat compartments in the temporal and middle face. According to the anatomical characteristics, a targeted fat grafting technique was established with the frontal hairline and the oral commissure corner mucosa as the entry points. In the clinical study, 46 patients were evaluated by 3D scanning 6 months after the last fat grafting. The amount of fat grafts in the temporal region was (17.84±8.47) ml and (11.2±2.44) ml was left after operation, and the survival rate was 63%. The amount of fat grafts in mid-face was (26.81±10.36) ml and (16.09±4.48) ml was left after operation, and the survival rate was 60%. Overall satisfaction rate of patients was 93% (43/46).Conclusions:Compartment-based targeted fat grafting is an accurate injection method, which meets the requirement of physiological augmentation. The trajectory of targeted fat grafting will further improve the efficacy and safety of injection.
