    ABSTRACT: Breast augmentation is one of the most commonly performed operations. Three-dimensional outcome simulation can be used to predict and demonstrate for the patient what the planned operation aims to achieve in terms of size and shape. However, there are still few studies in the literature that look at how close the simulation is to the actual postoperative result and how patients perceive the accuracy and usefulness of the simulation. A prospective series of 150 patients underwent breast augmentation following consultation with the aid of three-dimensional simulation images. These patients were evaluated with a questionnaire 6 months postoperatively. A retrospective chart review of 52 patients whose three-dimensional simulations were compared with the postoperative photographs were evaluated and graded by an independent panel of investigators. The independent panel graded the overall similarity of the three-dimensional simulations to the actual breasts with a total average score ± SD of 7.5 ± 0.80 (range, 4.5 to 8.9) using a visual analogue scale ranging from 1 to 10. The highest average score was given to projection, breast width, and height (7.8); the lowest average score was given to intermammary distance (7.0). Eighty-six percent of patients felt the simulated image was very accurate in predicting the actual result of their breasts. Patients prefer a center that offers three-dimensional imaging technology; they feel that the simulation is very accurate and helps them very much in choosing the implant; if they could go back in time, they would choose the same implant again.

    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.
