Crowdsourcing Aesthetic Preferences of the General Population Presenter: Alexandra Bucknor, MBBS, MRCS, MSc Co-Authors: Austin D. Chen, BS; Parisa Kamali, MD; Anmol S. Chattha, BA; Patrick P.

Lin, MD, MBA Affiliation: Beth Israel Deaconess Medical Center / Harvard Medical School, Boston, MA and overall appearance. Higher scores indicted a more positive response. RESULTS: A total of 203 responses were retrieved in the study period. The majority of respondents were Caucasian 61.6%) males (64.5%), with a mean age of 34.4 years. When comparing autologous with implant PMBR, mean overall appearance score was higher in autologous (3.07 vs. 2.83, p<0.001), as was that of the mean shape score (3.24 vs. 3.10, p=0.002), nipple score (3.06 vs. 2.87, p<0.001), scarring score (3.44 vs. 2.95, p<0.001), natural appearance score (3.29 vs. 2.79, p<0.001). On multivariate analysis, autologous PMBR was predictive of a higher preference score compared with implant PMBR (OR 1.42, CI 1.24–1.64). CONCLUSION: The public demonstrated an overall preference for the aesthetics of autologous over implant-based post-mastectomy breast reconstruction, independent of respondent characteristics. This information may provide further evidence supporting the use of autologous postmastectomy breast reconstruction. Reference Citations: 1.

INTRODUCTION: Post-mastectomy breast reconstruction (PMBR) is important for many women undergoing treatment for breast cancer; studies show that PMBR can improve body image, sexuality and overall quality of life.1 Aesthetic outcome is a significant component of patient satisfaction after PMBR and historically, has primarily been evaluated by patient and surgeon.2 The aim of this study is to evaluate public opinion of autologous and implant-based breast reconstruction. METHODS: In February 2017, a survey was distributed via a Crowdsourcing platform to members of the general population. Respondents rated the results of fourteen women’s breast reconstructions following treatment (seven autologous and seven implant-based PMBRs), ranking the attractiveness using a Likert scale with regard to shape, symmetry, nipples, natural appearance A Randomized Placebo-Controlled Double Blind Study of Intercostal Nerve Block Versus Incisional Infiltration with Bupivacaine for Postoperative Pain Control after Subpectoral Breast Augmentation Presenter: Surawej Numhom, MD Authors: Ngamcherd Sitpahul, MD; Wichuda Limpiangkanan, MD; Nuj Tontisirin, MD; Panuwat Lertsithichai, MD Affiliation: Ramathibodi Hospital, ­Mahidol University, Bangkok INTRODUCTION: Breast augmentation is among the most popular surgery procedures performed in the Asian countries.
