ABSTRACT: The aesthetic results of augmentation mammaplasty are essentially determined by the size and the shape of the implant as well as its position on the chest. To achieve successful aesthetic results, customized surgery planning based on a reliable visual concept of the prospective surgery outcome and quantitative methods for assessment of three-dimensional (3D) breast shape could be of considerable additional value. This report evaluates a novel method for customized planning and quantitative optimization of breast augmentation based on 3D optical body scanning of the patient's breast and computational modeling of soft tissue mechanics. This method allows a 3D photo-realistic appearance of postsurgery breasts to be simulated for different surgical scenarios. It also allows the result of a virtual simulation to be implemented using measurements derived from a computationally predicted breast model. A series of clinical studies are presented that demonstrate the feasibility and accuracy of the proposed approach for customized 3D planning of breast augmentation, including direct comparison between simulated and postsurgery results. Our experimental results show that for 89% of the breast surface, the average difference between the simulated and postsurgery breast models amounts to less than 1 mm. The presented method for customized planning of augmentation mammaplasty enables realistic prediction and quantitative optimization of postsurgery breast appearance. Based on individual 3D data and physical modeling, the described approach enables more accurate and reliable predictions of surgery outcomes than conventionally used photos of prior patients, drawings, or ad hoc data manipulation. Moreover, it provides precise quantitative data for bridging the gap between virtual simulation and real surgery.
