Chest masculinization surgery is increasing in prevalence. However, the ideal location of the nipple-areolar complex (NAC) is unknown. Our purpose was to determine the most aesthetically favorable male NAC position for use in chest masculinization through crowdsourcing.
Using Adobe Photoshop CC 2017, 8 locations for the NAC were created based on previous literature descriptions. Amazon Mechanical Turk was utilized as a crowdsourcing interface—respondents were asked to rank the top 3 most favorable and least favorable images. Analysis of variance with subsequent Tukey HSD was used for a statistical comparison of favorability scores for different NAC localizations. Values were considered significant with P < 0.05.
Eight hundred nineteen respondents participated in the survey. NAC positions of Images C (mean score = 1.9222) and A (mean score = 1.7365) received higher favorability scores than those of Images D, E, F, G, and H (all P < 0.05). There were no significant differences between Images C and A (C versus A: P = 0.6412). NAC localizations from Images G (mean score = −2.0353) and H (mean score = −1.6908) received lower favorability scores than Images A, B, C, D, E, and F (all P < 0.05). There were no significant differences between Images G and H (P = 0.2279).
Most respondents preferred Images C and A, and few favored Images G and H, suggesting that lateral NAC placement is favored over more medial localizations. Additionally, both Images C and A utilize relatively inferior NAC placements. Therefore, we recommend a location inferior and lateral to the NAC. Ultimately, NAC localization during chest masculinization will be the result of shared decision-making between the patient and the surgeon to fulfill each patient’s aesthetic goals.
