Abstract Background In the past decade there has been a dramatic increase in trends related to body-shaping procedures. According to the American Society of Plastic Surgeons, nearly 300,000 breast augmentation procedures were conducted in 2019. 1 Learning the ideal shape of a breast, and which esthetics lead to public perception of the most attractive breast is beneficial to properly performing these procedures. Objectives The authors aimed to quantify public perception of the attraction to breast shape by measuring public opinion for various esthetic elements of breast anatomy, and linking this to various demographic factors. Methods Survey responses were collected from 1,000 users of Amazon Mechanical Turk to collect demographic data as well as ask users to rank preferences for randomized image panels of breast proportions. Responses were collected and analyzed to find the overall ideal breast proportions. Results In total, 1000 responses were collected, with 960 being used for analysis. Overall, a majority of respondents were male (60%), with a plurality belonging to the age group of 25-34 years old (49.3%). The most notable preference between all groups was the breast projection proportion and the preferred nipple direction, with preferences of 1.0 and a frontal nipple direction, respectively. Breast width to shoulder width ratio also had a clear preference among the crowd, with 105% being the preferred percentage, and the 25-34 age group having a very strong preference for this. Conclusions The authors used a crowdsourcing survey technique with randomized image panels to analyze ideal breast preference using images of various anatomical traits of the female breast. It was concluded that crowdsourcing can be a favorable technique for learning ideal overall preferences for specific anatomy.

Abstract PURPOSE: The aim of this study was to determine the knowledge of risk factors and symptoms of breast cancer among Yemeni nurses during the conflict. METHODOLOGY: A cross-sectional design was carried out among 392 randomly selected participants. The instrument consists of 20 items, 12 general awareness statements, and 8 curability statements with a 0.711 reliability coefficient. Data analysis was performed using SPSS version 25. RESULTS: Most of the nurses were female (69.5%), with a mean age of 28.54, with monthly income less than 200 USD (54.3%). About 21.4% of the participants were smokers. Among all participants, the most frequently mentioned risk factor were breastfeeding, reducing the risk of breast development (86.2%), followed by physical activities lowers the developing risk of breast cancer (79.1%). Over time, the myth of the constant irritation due to the tight bra may cause breast cancer reported by women more than male nursing students. In this respect, men were better knowledgeable than women (P=0.001). Females, however, were more aware than males that women who bear their first child before 30 are more to develop breast cancer (P=0.017). Income is significantly associated with the level of knowledge among nurses. The most frequently mentioned breast symptoms among all participants were a pain in the breast (82.9%), followed by changes in the breast shape (79.1%). CONCLUSIONS: Income is significantly associated with the level of knowledge among nurses. The myth about breast cancer is dominant among nurses in Yemen. Therefore, there is an urgent need to educate nurses on breast health.

In the research of breast morphology, numerous breast features are measured, whereas only a few parameters are adopted for classification. Therefore, how to extract the key variables from the multi-dimensional features in a rational way is an issue that is focused upon. This study aimed to reduce the complexity of the dimensionality reduction for further improving the objectivity and interpretability of the selected breast features. Since the random forest (RF) algorithm can quantify the feature importance during training, the method was adopted to determine the optimal breast features for classification and recognition in this paper. Firstly, the anthropometric data of 360 females from northwestern China aged from 19 to 27 years were measured by non-contact three-dimensional body scanning technology and the contact manual measurement method. Then, the k-means clustering was applied to categorize breast shapes, and the RF algorithm was utilized to quantify and rank the importance of 25 breast features. Finally, to verify the availability of the RF algorithm on breast feature selection, the t-distributed stochastic neighbor embedding method was adopted to visualize the distribution of breast shape clusters into two dimensions. Meanwhile, four neural networks were determined to recognize the breast morphology. The results demonstrate that fewer breast features can effectively increase the accuracy of breast shape classification and recognition. The best performance of breast shape classification and recognition is obtained when the number of breast features is 13. In this case, the average Hamming loss of four neural networks is the smallest (0.1136). Interestingly, the bust circumference and the horizontal curve of breasts across the bust points are found to be the most important of the 25 breast features in this paper. The importance of the breast curve features is higher than that of the breast cross-sectional features, while the breast positioning features have the lowest importance. Meanwhile, the RF algorithm is verified to be more effective than traditional dimensionality reduction methods, such as principal component analysis, hierarchical clustering, and recursive feature elimination. The approach developed in this paper can be generalized to the dimensionality reduction of other body morphology.

Breast reconstruction during breast-conserving surgery (BCS) can improve the breast shape. This study introduces breast reconstruction in BCS with two types of acellular dermal matrix (ADM). The study included 134 patients who underwent BCS due to breast cancer from February 2018 to May 2021. This study was conducted by one surgeon, and is the result of a three-year study. The patient group who underwent BCS using ADM was mainly targeted at patients with minor to severe defects after the operation. The average age of the patients was 51.8 years, and the body mass index (BMI) was 23.8 kg/m. The specimen weight was 30–120 g. The average surgical time, including reconstruction, was 100.4 min, combined with reconstruction. There were minor complications in six patients. The advantage of using ADM is that it can quickly correct the shape of the breast after conventional BCS surgery. Pellet-type ADM, rather than sheet-type, can create a breast shape similar to that before surgery. Breast reconstruction using ADM can be an easy and convenient method for making a better shape from BCS.

In the process of bra cup customization, the matching between bra cup surface and breast shape largely depends on the practical experience of designers. To achieve effective customization, this study proposes an inverse design method. This method prescribes the surface of the main test section and subsequently optimizes the corresponding shape of the bra cup, thus minimizing the supremum of pressure in the target region. The optimization framework is mainly based on the particle swarm optimization algorithm and Kriging surrogate model. The inner surface of the bra cup represents the study model, and the three-dimensional morphology of the bra cup is characterized by the free-form deformation. The result exhibits a reduction of 22.51% in the pressure of the design cup as compared to the body size cup. The developed method can contribute to the engineering and personalized customization of the bra cup, thus further improving the fitting of the bra cup.

Abstract Background Autologous fat transplantation for breast augmentation represents an increasingly interesting technique in plastic surgery. Only a few standardized procedures are available. Hybrid augmentation mastopexy combines the benefits of autologous fat transplantation and implant-based breast augmentation mastopexy, reducing implant-related complications and prothesis size. Herein, we describe our surgical approach as a “hybrid aesthetic surgery.” Methods A retrospective analysis of all patients who underwent hybrid breast augmentation and lifting with simultaneous fat grafting was carried out. Clinical outcomes, ultrasound evaluation of upper pole fullness, aesthetic postoperative results, and complications were examined. Results Eighteen patients with a mean age of 33 years (range: 24–52 years) and mean BMI of 25.8 kg/m2 (range: 21.4–32.1 kg/m2) were included in this study. Mean injected fat volume per breast was 115 cc (range: 78–144 cc). Patients were followed up for a mean of 9.4 months (range: 6–24 months). No fat necrosis or major complications were encountered during the follow-up. Patient satisfaction was high in terms of breast shape, size, and coverage of the breast implant. No recurrence of ptosis was observed yet and no secondary revision surgery was performed. Conclusions Hybrid mastopexy augmentation is an effective and safe procedure that combines the benefits of autologous fat grafting and implant-based breast augmentation. The transfer of autologous soft tissue allows obtaining a natural breast shape, reducing the onset of rippling and prothesis size. The reduction of prothesis size prevents ptosis recurrence but provides the desired projection. This reliable option improves long-term breast shape with elevated patient’s satisfaction. Level of evidence: Level IV, therapeutic study.

Abstract Purpose The transverse musculocutaneous gracilis (TMG) flap is as a valuable alternative in autologous breast reconstruction. The purpose of this study was to evaluate the donor site morbidity and secondary refinement procedures after TMG flap breast reconstruction. Methods A retrospective study was conducted, including all patients who received TMG flap breast reconstructions, from January 2012 to August 2019. Primary outcomes were surgical site complications of the donor site and secondary refinement procedures carried out for aesthetic or reconstructive purposes for the medial thigh. Secondary outcomes of interest were lipofilling procedures for optimization of the reconstructed breasts. Results Ninety-nine patients received 159 TMG flaps for breast reconstruction. Patients’ mean BMI was 23.5 (15.6–32.5) kg/m2. Bilateral breast reconstructions were performed in 60.6%. The mean flap volume was 330 (231–440) g. Surgical site complications occurred in 14.5% of the TMG donor sites and wound dehiscence was the most common complication (9.4%). Lymphedema occurred in 1.8% of the donor thighs. Aesthetic refinement procedures were performed in 25.2% on the donor thigh or contralateral thigh. Secondary lipofilling was performed in 54.1% of the reconstructed breasts and fat was harvested in only 11.9% from the legs. Conclusion The TMG flap breast reconstruction combines low donor site morbidity with adequate volume for appealing breast results, particularly in slim-to-normal weight patients. However, patients should be informed about the likelihood of secondary refinement procedures on the donor site and the need of lipofilling to optimize the breast shape and volume.
