Correction of breast asymmetry by autologous fat grafting with the aid of 3D laser-scanning technology

Abstract

BackgroundCurrently, the lack of clinically accurate measurement and evaluation methods for breast asymmetry has considerably limited the use of autologous fat grafting in the correction of breast asymmetry. ObjectiveThis study calculated the volume difference in the bilateral breasts by three-dimensional (3D) laser scanning technology, established a bridge between digitalization and surgery to guide the correction of breast asymmetry by autologous fat grafting, and evaluated the surgical effect. MethodsIn the experimental group (3D group), the measurement range was defined by standardized methods, the algorithm to calculate the volume difference in the bilateral breasts was determined by the established software instructions, and the volume of intraoperative autologous fat grafting was guided by personalized data. In the control group, the volume of intraoperative autologous fat grafting was determined based on the surgeon's visual assessment and surgical experience. ResultsThe volume difference in the bilateral breasts was less at 12 months after surgery (P < 0.05), the satisfaction of patients was higher (P < 0.05), and the reoperation rate was lower (P < 0.05). The incidence of postoperative complications was low in both groups (P > 0.05). Conclusions3D laser scanning technology can be used as a bridge between digitalization and surgery to significantly improve the surgical effect of autologous fat grafting in the correction of breast asymmetry, with high patient satisfaction and high clinical application value.
