Abstract
BACKGROUND The choice of implant shape (anatomic or round) is one of the most critical issues for breast augmentation. Determining whether there are differences in the postoperative breast morphology of the 2 implants is pivotal for surgical planning. This issue has been controversial and lacking in evidence. The aim of this study was to provide reference for implant selection by comparing breast morphology after dual-plane augmentation with anatomic and round implants using 3-dimensional scanning technology. METHODS Patients with implant volume less than 300 mL who underwent transaxillary dual-plane augmentation were included in this study and were grouped according to implant shape. Three-dimensional scans were performed preoperatively and 6 months postoperatively. Postoperative breast height (BH), breast width (BW), BH of upper pole (BHUP), BH of lower pole (BHLP), breast projection (BP), BP of upper pole (BPUP), and BP of lower pole (BPLP) were measured separately, resulting in corresponding ratios (BH/BW, BHUP/BHLP, BP/BH, BPUP/BPLP). Breast volume, and the volumes of each pole (breast volume of upper pole [BVUP], breast volume of lower pole [BVLP]) and its ratio (BVUP/BVLP) were calculated. Correlation and regression analysis on the influencing factors of breast volume were performed. RESULTS Thirty patients with anatomic implants and 26 with round implants were enrolled in this study. The mean volumes of anatomic and round implants were 260.5 ± 26.7 and 267.9 ± 21.7 mL (P = 0.192). The ratios of BH/BW in the 2 groups were 1.39 ± 0.12 and 1.37 ± 0.19, respectively (P = 0.582). The BHUP/BHLP values of 2 groups were 1.35 ± 0.22 and 1.41 ± 0.25 (P = 0.160). Two sets of BPUP/BPLP were 0.68 ± 0.19 and 0.73 ± 0.17 (P = 0.133). The ratios of BP/BH in the 2 groups were 0.39 ± 0.08 and 0.39 ± 0.06 (P = 0.830). The BVUP/BVLP ratios for both groups were 0.75 ± 0.11 and 0.77 ± 0.12 (P = 0.287). There was a volume loss rate of 13.3% ± 3.9% and 13.9% ± 5% (P = 0.489). The postoperative volume showed a positive correlation with both the preoperative volume and the implant volume. CONCLUSIONS For patients with breast dysplasia undergoing transaxillary dual-plane augmentation with anatomic or round implants less than 300 mL, the difference in postoperative breast morphology is not obvious. Using these 2 shapes of implants results in a similar degree of volume loss.

Abstract
Three-dimensional Surface Imaging (3DSI) has become a valuable tool for planning and documenting surgical procedures. Although surface scanners have allowed for a better understanding of breast shape, size, and asymmetry during patient consultation, its use has not been included in intraoperative assessment so far. Validation of the reliability of the intraoperative use of a portable handheld 3DSI equipment as a tool to evaluate morphological changes during breast augmentation surgery. The patients who underwent bilateral subpectoral breast augmentation through an inframammary incision were included in this study. Intraoperative 3DSI was performed with the Artec Eva device, allowing for visualization of the surgical area before incision, after use of breast sizers and implant, and after wound closure. Intraoperatively manual measurements of breast distances and volume changes due to known sizer and implant volumes were in comparison with digital measurements calculated from 3DSI of the surgical area. Bilateral breasts of 40 patients were 3D photographed before incision and after suture successfully. A further 108 implant sizer uses were digitally documented. There was no significant difference between manual tape measurement and digital breast distance measurement. Pre- to postoperative 3D volume change showed no significant difference to the known sizer and implant volume.

Abstract
BACKGROUND Traditional methods of breast implant size selection provide limited ability to demonstrate postoperative outcomes. Three-dimensional (3D) imaging provides an opportunity for improved patient evaluation, surgical planning, and evaluation of postoperative breast appearance. OBJECTIVES The authors hypothesized that preoperative 3D imaging for patients undergoing breast augmentation would improve patient satisfaction and understanding of expected surgical outcomes. METHODS A retrospective review of patients undergoing breast augmentation by a single surgeon over a 3.5-year period was performed. Patients presenting after the VECTRA was purchased had preoperative 3D imaging, while patients presenting before this did not. Eligible patients received a BREAST-Q questionnaire designed for postoperative evaluation of breast augmentation. They also received a second survey that evaluated expected vs actual breast outcomes. RESULTS In total, 120 surveys were mailed and 61 patients (50.8%) returned the survey. The 3D imaged group had improved BREAST-Q scores regarding satisfaction with outcome, surgeon, and physical well-being compared with the group that did not. The imaged group also had higher size, shape, and overall breast correlation scores, confidence in implant size selection scores, and communication with surgeon scores. The differences between the 2 groups were not statistically significant. CONCLUSIONS Three-dimensional imaging is a valuable tool in breast surgery. Although this study showed improvement in patient satisfaction and predicted outcome scores in the 3D imaged group, the results were not statistically significant. With the majority of patients reporting that they would choose 3D imaging, it appears to instill confidence in patients regarding both surgeon and implant selection. LEVEL OF EVIDENCE 4

Abstract
BACKGROUND Dual-plane breast augmentation is a popular cosmetic procedure. However, objective evaluations on the effects of dual-plane breast augmentation on breast morphology are lacking. This study evaluated the breast morphological changes and correlative factors after dual-plane anatomic implant augmentation with a periareolar incision via a Vectra 3-dimensional (3D) scanning technique. METHODS The dynamic changes in linear distance, breast projection, nipple position, and breast volume and surface over time (preoperatively; 1 month, 3 months, 6 months, and 12 months after surgery) were analyzed in 21 patients with the Vectra 3D scanning technique. In another group of 65 patients, the influence of the implant parameters and tissue characteristics of the patients on breast morphological changes were evaluated. RESULTS The breast measurements changed significantly up to 6 months postoperatively and remained stable thereafter. The inframammary fold dropped by 0.8 cm at 1 month postoperatively and by 0.5 cm in the following 11 months. The preoperative implant volume and a lower pole skin elasticity lead to an increase in the nipple-to-inframammary fold distance. Compared with the expected values, the final volume was 10.9% smaller, and the projection was 25% smaller. Both the reduced volume and projection were correlated with the implant parameters and preoperative values. The nipple level was slightly elevated by approximately 0.8 cm. CONCLUSIONS This study provides objective information regarding the breast morphological changes and correlative factors after dual-plane breast augmentation. These information may help to further understand the operation effects of dual-plane breast augmentation and to guide medical practice.

Abstract
BACKGROUND Three-dimensional surface imaging (3DSI) has shown promise for plastic surgeons to objectively assess changes in body contour and breast volume. OBJECTIVES To assess the surgical outcome after bilateral subcutaneous mastectomy (BSM) and water jet-assisted liposuction (WAL) as treatment for idiopathic gynecomastia, using 3DSI to document changes regarding nipple-areolar complex (NAC) and breast volume. METHODS Thirty male patients (Simon II A to B) receiving BSM and WAL were enrolled. Eight subjects received additional mastopexy and NAC reduction. Use of a Vectra 3D Imaging System® before and 6 months after surgery provided data regarding changes of NAC placement and NAC and breast dimensions. The sum volume of intraoperatively approximated lipoaspirate before and after centrifugation and mastectomy specimens quantified using water displacement were compared with 3D-assessed differences in volume. RESULTS When compared to the NAC dimensions defined during surgery, patients receiving NAC reductions showed nonsignificant postoperative changes in NAC dimensions. Patients without additional mastopexy showed a significant (p < 0.001) vertical (15.7 ± 14.3%) and horizontal (17.1 ± 15.0%) reduction in NAC diameter. 3D volume changes (92.8 ± 26.4 mL) showed significant differences (p < 0.001) 6 months after surgery compared to the intraoperatively measured lipoaspirate before (182 ± 54.5 mL) and after (120 ± 34.6 mL) centrifugation. CONCLUSION Although it is clear that patient satisfaction must remain the prime focus of surgical body contouring, 3DSI has proven valuable to objectively demonstrate both the anticipated outcome and further findings regarding treatment of idiopathic gynecomastia.

Abstract
Introduction: Three-dimensional (3D) scanners are widely used in medicine. One of the applications of 3D scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. The aim of this study was to evaluate the precision and accuracy of a modified 3D scanner fabricated in this study. Methods: In this work, a 3D scan of the human body was obtained using DAVID Laser Scanner software and its calibration background, a linear low-power laser, and one advanced webcam. After the 3D scans were imported to the Geomagic software, 10 anthropometric dimensions of 10 subjects were obtained. The measurements of the 3D scanner were compared to the measurements of the same dimensions by a direct anthropometric method. The precision and accuracy of the measurements of the 3D scanner were then evaluated. The obtained data were analyzed using an independent sample t test with the SPSS software. Results: The minimum and maximum measurement differences from three consecutive scans by the 3D scanner were 0.03 mm and 18 mm, respectively. The differences between the measurements by the direct anthropometry method and the 3D scanner were not statistically significant. Therefore, the accuracy of the 3D scanner is acceptable. Conclusion: Future studies will need to focus on the improvement of the scanning speed and the quality of the scanned image.

Abstract
BACKGROUND Accurate volumetric analysis is an essential component of preoperative planning in both reconstructive and aesthetic breast procedures towards achieving symmetrization and patient-satisfactory outcome. Numerous comparative studies and reviews of individual techniques have been reported. However, a unifying review of all techniques comparing their accuracy, reliability, and practicality has been lacking. METHODS A review of the published English literature dating from 1950 to 2015 using databases, such as PubMed, Medline, Web of Science, and EMBASE, was undertaken. RESULTS Since Bouman's first description of water displacement method, a range of volumetric assessment techniques have been described: thermoplastic casting, direct anthropomorphic measurement, two-dimensional (2D) imaging, and computed tomography (CT)/magnetic resonance imaging (MRI) scans. However, most have been unreliable, difficult to execute and demonstrate limited practicability. Introduction of 3D surface imaging has revolutionized the field due to its ease of use, fast speed, accuracy, and reliability. However, its widespread use has been limited by its high cost and lack of high level of evidence. Recent developments have unveiled the first web-based 3D surface imaging program, 4D imaging, and 3D printing. CONCLUSIONS Despite its importance, an accurate, reliable, and simple breast volumetric analysis tool has been elusive until the introduction of 3D surface imaging technology. However, its high cost has limited its wide usage. Novel adjunct technologies, such as web-based 3D surface imaging program, 4D imaging, and 3D printing, appear promising.

Abstract
A multi-view three-dimensional stereophotogrammetry system was developed to capture 3D shape of breasts for breast cancer patients. The patients had received immediate unilateral breast reconstruction after mastectomy by the extended latissimus dorsi flap and without contralateral surgery. In order to capture the whole breast shape including the inframammary fold, the patients were introduced to the imaging room and leaned over the imaging rig to open up the inframammary fold and to expose the entire area of each breast. The imaging system consisted of eight high-resolution ([Formula: see text] pixels) digital cameras and four flash units. The cameras were arranged in four stereo pairs from four different view angles to cover the whole surface of the breasts. The system calibration was carried out ahead of every capture session, and the stereo images were matched to generate four range images to be integrated using an elastic model proposed. A watertight breast mesh model was reconstructed to measure the volume of the breast captured. The accuracy of using the developed multi-view stereophotogrammetry system for breast volume measurement was 11.12cc with SEM 7.74cc, comparing to the measurements of the water displacement method. It was concluded that the 3D stereophotogrammetry image system developed was more reliable than the method of water displacement.

Abstract
BACKGROUND There are many methods of measuring the breast and their clinical applications are well described in the literature. However, there has been no attempt to compare these various methods to allow the user to have a broad overview of the subject. The authors have attempted to summarise all the available methods to measure the breast in this article to provide a useful reference for all. METHODS A comprehensive literature search of PubMed was performed, and the resulting articles were screened and reviewed. The data regarding the methods' mechanism, reliability, time and cost were evaluated and compared. RESULTS A total of 74 articles dating from 1970 to 2013 were included in this study. All of the methods can be classified into those that measure (1) volume, (2) shape and (3) surface area. Each category consists of several methods that work through different mechanisms and they vary in their reliability and feasibility. Based on their mechanism, the volume measurement methods were further grouped into the natural shape methods, the stereological method, the geometrical methods and the mathematical modelling method. CONCLUSIONS More objective breast evaluation can be achieved if all three dimensions (volume, shape and surface area) are considered. In the volume measurements, 3D modelling and the MRI are the most reliable tools. Linear measurement (geometry) and mathematical modelling are less accurate but are more economical. In the shape measurements, besides the traditional linear measurement, 3D methods that can deliver colour-coded maps and Swanson's 2D photographic measurement system are capable of depicting and tracking breast shape changes after surgery. Although the surface area metric has not been used extensively, it has potential in clinical and research applications.

Abstract
Background The dual-plane technique has been widely used in augmentation mammaplasty procedures. However, there are some concerns about aesthetic contour maintenance for long time after muscle releasing. This study aims to track and analyze breast dynamic morphological changes after dual-plane breast augmentation with three-dimensional (3D) scanning technique. Methods Thirteen dual-plane anatomic implant augmentation patients underwent 3D scanning preoperatively (pre-OP) and postoperatively in four time points (1 month: post-1M, 3 months: post-3M, 6 months: post-6M and 12 months: post-12M). The linear distance, breast projection, nipple position, breast volume and breast surface area were measured and analyzed on the 3D models over time. Results Compared with post-12M, no significant differences were found in distances of nipple to midline, nipple to inframammary fold and sternal notch to the level of inframammary fold after 6 months in both straight-line distance and its projection on surface. The distances between sternal notch and nipple had no significant difference after post-1M. Breast volume changes had no significant difference after post-3M. The volume and area percentage of upper pole decreased while the lower pole’s increased gradually. The surface showed no significant changes after post-1M. The changes of breast projection had no significance after post-1M either. The nipple moved 1.0±0.6 cm laterally(X axis), 0.6±0.7 cm upward(Y axis) and 2.3±1.1 cm anteriorly (Z axis) at post-12M, and the differences were not significant after post-1M. Conclusions 3D scanning technique provides an objective and effective way to evaluate breast morphological changes after augmentation mammaplasty over time. Dual-plane augmentation optimizes breast shape especially in the lower pole and maintains stable aesthetic outcome during the 12 months follow-up. Most of the contour changes and the interadaptation with the implant have completed 6 months after operation. Therefore, 6 months could be chosen as a relatively stable observing period in the assessment of postoperative outcomes of dual-plane breast augmentation.

Abstract
BACKGROUND Measurement of volumetric change after aesthetic and reconstructive breast surgery is of great significance to plastic surgeons. This study aimed to investigate the influence of respiration on measurement of breast volumetric change via a three-dimensional (3D) scanning technique. METHODS In this study, ten augmentation mammaplasty patients received preoperative 3D scanning in different respiration states at three time points: the end of normal exhalation (ENE1), the end of normal inhalation (ENI), and the end of normal exhalation again (ENE2). Using Geomagic Studio 12 software, breast volumetric change error (BVCE) was measured between the ENE1 scan and the ENI scan (R1) and between the ENE1 scan and ENE2 scan (R2). Three-dimensional deviation, defined as the shortest distance from one scan to any point on the other scan, was measured in R1 and R2. A paired-sample t test was used to compare the means of BVCE and the 3D deviation between R1 and R2. Pearson's correlation coefficient was calculated between 3D deviation and BVCE. For the analysis, SPSS program version 16 was used. Differences were considered statistically significant at P values lower than 0.05. RESULTS The mean breast volume was 352.3 ± 52.7 ml, and BVCE was significantly lower in R1 than in R2 (9.7 vs. 21.3 ml; P = 0.000). The 3D deviation was significantly higher in R2 than in R1 (1.600 vs. 0.887; P = 0.000). In the analysis, BVCE was not correlated significantly with 3D deviation in R1 (P = 0.157) but was significantly correlated with 3D deviation in R2 (correlation coefficient = 0.766; P = 0.000). CONCLUSIONS Keeping patients in the same respiration state is crucial for accurate measurement of breast volumetric change via the 3D scanning technique.

Abstract
BACKGROUND 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. METHODS 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. RESULTS 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. CONCLUSIONS 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
In this work, we compared accuracy, repeatability, and usability in breast surface imaging of 2 commercial surface scanning systems and a hand-held laser surface scanner prototype coupled with a patient's motion acquisition and compensation methodology. The accuracy of the scanners was assessed on an anthropomorphic phantom, and to evaluate the usability of the scanners on humans, thorax surface images of 3 volunteers were acquired. Both the intrascanner repeatability and the interscanner comparative accuracy were assessed. The results showed surface-to-surface distance errors inferior to 1 mm and to 2 mm, respectively, for the 2 commercial scanners and for the prototypical one. Moreover, comparable performances of the 3 scanners were found when used for acquiring the breast surface. On the whole, this study demonstrated that handheld laser surface scanners coupled with subject motion compensation methods lend themselves as competitive technologies for human body surface modeling.

Abstract
BACKGROUND Currently, postoperative outcome analysis in breast augmentation is essentially subjective, and objective evaluation of treatment efficacy is lacking. This study evaluates the influence of anatomic and round implant parameters on breast contour changes after subpectoral breast augmentation using three-dimensional (3D) surface imaging. METHODS 3D surface breast scans of 17 patients (34 breasts) undergoing subpectoral breast augmentation with round implants and of ten patients (20 breasts) receiving anatomic implants via an axillary approach under endoscopic assistance or a submammary fold incision were obtained before and 6 months postoperatively. 3D linear distance, breast volume, and surface measurement were correlated with the implanted round and anatomic implant parameters, and the resulting breast shape changes were evaluated. RESULTS Total breast volume changed in correlation with the implant size (2.4% difference; r=0.894; p<0.001). Implant volume and type influence the nipple-to-inframammary fold distance (N-IMF). Every inserted 100 ml implant volume enlarges the N-IMF distance by 0.8 cm (anatomic>round; p=0.01). Postoperatively, the IMF dropped by an average of 1.3 cm for round implants and by 1.1 cm for anatomic implants, without relevant differences between the applied surgical incision and the selected implants (p>0.05). Breast projection increased significantly more with anatomic implants (2.4 cm) than with round implants (1.7 cm) (p=0.01). The breast projection increase was 22% less than expected for round implants and 25% less than expected for anatomic implants based on the manufacturer implant parameters (p<0.01), without essential differences regarding the surgical incision. CONCLUSIONS 3D breast shape changes induced by round and anatomic implants after subpectoral augmentation mammaplasty are objectively documented including breast projection, volume, and N-IMF distance changes. 3D surface imaging may have a potential clinical contribution to objective surgical outcome research.

Abstract
Although there are many three-dimensional imaging systems currently available on the market, all of them require a high degree of interaction on the part of the user, making them clinically impractical. Moreover, though claims have been made regarding the validity of these systems for imaging the breast form, there have been no previous reports validating any commercially-available implant simulation models in the plastic surgery literature. In this article, the authors describe the development and evaluate the efficacy of a novel four-dimensional (automated three-dimensional) breast imaging system, validating it as an evidence-based simulation tool for patient consultation, surgical planning, and outcomes analysis in cosmetic breast augmentation. This report, based on a series of longitudinal correlation studies with several patient cohorts, found a highly statistically significant degree of correlation and reliability between the automated measurements obtained with the four-dimensional system and manual measurements.

Abstract
BACKGROUND No publications exist describing the impact of three-dimensional imaging on the consultation process for breast augmentation, nor have existing software products claiming simulation features been validated. OBJECTIVES The authors describe the application of four-dimensional technology during patient consultation to assist in planning implant size and type. METHODS Forty-six primary breast augmentation patients underwent preoperative consultation with 4D simulation software; 35 out of 46 also received follow-up imaging. At six months postoperatively, simulated measurements were compared to actual measurements and questionnaires were mailed to patients asking them to assess the imaging experience. A follow-up phone survey 18 months postoperatively examined the persistence of patient attitudes about implant size and imaging. Practice productivity was evaluated by comparing specific parameters (such as scheduling rates) between three separate time periods for the same clinic. RESULTS Across all parameters, breast augmentation simulations correlated highly with positive surgical outcomes (R-value = 0.68). The majority (95%) of patients believed the simulations were accurate; 89% also expressed that it enhanced trust in the surgeon and 74% reporting that it helped in choosing an implant size. Despite 48% also indicating that they would select a larger implant if they were to undergo surgery again, no patients have undergone reoperations of any kind. Compared to historical controls, scheduling rates in the practice increased from 40% to 77% after addition of simulation software. CONCLUSIONS 4D breast imaging appears to be an accurate system for analysis, planning, simulation, and patient education for women considering primary breast augmentation, and application of this technology during the consultation process was correlated with a high degree of patient satisfaction and practice productivity.

Abstract
This study develops an objective breast symmetry evaluation using 3-D surface imaging (Konica-Minolta V910(®) scanner) by superimposing the mirrored left breast over the right and objectively determining the mean 3-D contour difference between the 2 breast surfaces. 3 observers analyzed the evaluation protocol precision using 2 dummy models (n = 60), 10 test subjects (n = 300), clinically tested it on 30 patients (n = 900) and compared it to established 2-D measurements on 23 breast reconstructive patients using the BCCT.core software (n = 690). Mean 3-D evaluation precision, expressed as the coefficient of variation (VC), was 3.54 ± 0.18 for all human subjects without significant intra- and inter-observer differences (p > 0.05). The 3-D breast symmetry evaluation is observer independent, significantly more precise (p < 0.001) than the BCCT.core software (VC = 6.92 ± 0.88) and may play a part in an objective surgical outcome analysis after incorporation into clinical practice.

Abstract
BACKGROUND: The First International Breast (Implant) Conference was held by the EAoS® (European Academy of Senology) in cooperation with the German Society of Senology during its 29th annual meeting in Düsseldorf, Germany, on 13 June 2009. METHODS: It was performed as a whole-day interactive workshop in which the standards of implant surgery within reconstructive and aesthetic breast surgery were discussed and defined by telecommunication dialogue voting. RESULTS: This article describes the conference results concerning pre- and post-procedural imaging in patients with breast implants. Both before and after augmentation, imaging is mandatory and provides essential information concerning tissue and implant integrity. Whereas mammography is the first-line method before surgery, ultrasound is the mainstay of post-procedural imaging. Cancer screening in augmented breasts generally follows the same guidelines as for non-augmented breasts. CONCLUSION: Whereas agreement about the indications for mammographical and sonographical evaluations is largely unanimous, there was substantial disagreement as far as the application of magnetic resonance imaging is concerned. There is an obvious demand for an evidence-based evaluation of this modality and the implementation of appropriate guidelines.
