Abstract
BACKGROUND: In body contouring surgery, some regions, such as the abdomen, thorax, upper limbs, and glutes, are prioritized over others, including the lower limbs, particularly the anterior thighs. This study aimed to identify anterior thigh preferences by age, sex, ethnicity, and region and assess their importance as a factor of female beauty by conducting an online survey. METHODS: Photographs of a 24-year-old female model were modified in two front-view and side-view panels. Through a survey on the Amazon Mechanical Turk platform, participants were asked to order the images from the most beautiful to the least beautiful, and the results were broken down by age, sex, ethnicity, and region. RESULTS: A total of 1000 respondents were surveyed, all of whom answered the survey without error; therefore, no one was excluded. Of the 1000 respondents, 504 were men (50.4%) and 496 were women (49.6%). The predominant age group was 26-35 years, with 443 people (44.3%), the region with the highest number of participants was North America, with 484 respondents (48.4%), and the predominant ethnicity was White, with 555 respondents (55.5%). The survey showed that the most beautiful images were image A on the side-view panel (25.9%) and image I on the front-view panel (28.5%)(P < 0.001). CONCLUSIONS: In the side view, the aesthetic preferences of the anterior thigh do not appear to be associated with the anterior projection. However, in the front view, the increase in width generates a beauty trend, but only up to an intermediate level, quantified in the ratio (0.44).
