The Public Face of Rhinoplasty: Impact on Perceived Attractiveness and Personality

Overview

This study tested whether rhinoplasty changes how strangers read a person's character, not just their appearance. Respondents recruited by crowd-sourcing compared side-by-side before and after photographs and rated which better represented each of eleven traits.

Sections of note

• Standardized before and after photographs of 10 Caucasian women who had primary rhinoplasty.
• Two additional women who had no facial surgery were randomly included as controls, giving 12 survey items.
• Photographs were placed side by side; respondents used a seven-point Likert scale where 1 favored the preoperative image, 7 the postoperative, and 4 meant no difference.
• 264 responses were received; t tests and analyses of variance were used.
• Postoperative images scored significantly higher in 10 of 11 categories: symmetry, youthfulness, facial harmony, likeability, trustworthiness, confidence, femininity, attractiveness, approachability, and intelligence, p below 0.00001.
• Preoperative images rated higher only in aggressiveness, p below 0.001.
• Controls showed no significant difference in any category except confidence, where the right-hand image was rated more confident, mean 4.19, p below 0.005.

What it means for a patient

• Strangers inferred personality traits, not just looks, from the postoperative photographs.
• The control finding is important: with two unoperated faces, respondents still favored the right-hand image on confidence, indicating a position bias in the survey design.
• Limits: 10 patients, all Caucasian women, still photographs, and crowd-sourced respondents rating strangers.
• Traits such as trustworthiness and intelligence are inferences observers make, not properties the surgery changed.

Why this paper matters

Social perception is often claimed as a benefit of cosmetic surgery without measurement, and this quantifies it across eleven traits. The consistency across categories is striking. The narrow patient sample and the control-group position effect temper how far the result carries.

Terms

• Crowd-sourcing: Recruiting survey respondents through an online platform.
• Likert scale: A response scale with ordered options, here seven points.
• Control image: A comparison pair where nothing was changed, used to detect survey bias.
• Facial harmony: How well facial features are judged to fit together.
• Analysis of variance: A statistical test comparing means across more than two groups.
