Prioritizing Native Breast Skin Preservation or Scar Symmetry in Autologous Breast Reconstruction? Using Crowdsourcing to Assess Preference.

BACKGROUND: Recent literature on autologous breast reconstruction suggests that such factors as scar symmetry and skin paddle size impact patient preferences more than preservation of native breast skin. Since patient satisfaction with plastic surgery procedures can be largely influenced by beauty standards set by the general public, this study used a novel crowdsourcing method to evaluate laypeople's aesthetic preferences for different bilateral autologous breast reconstructions to determine the relative importance of scar and skin paddle symmetry and preservation of native skin.

METHODS: Using Amazon's Mechanical Turk crowdsourcing marketplace, participants ranked images of reconstructions based on overall aesthetic appearance. Images were digitally modified to reflect 4 types of reconstruction: immediate (IR), delayed symmetric (DS), delayed asymmetric (DA), or mixed (MR).

RESULTS: DS was ranked most favorably (1.74), followed by IR (1.95), DA (2.93), and MR (3.34). Friedman rank sum and pairwise tests showed statistical significance for comparisons of all 4 reconstruction types. Likert ratings were higher for IR than for DA reconstructions for skin quality ( P = .002), scar visibility ( P < .001) , scar position ( P < .001), and breast symmetry, shape, and position ( P < .001). Ratings increased for all aesthetic factors following nipple-areolar-complex reconstruction ( P < .001).

CONCLUSIONS: More symmetric breast scars were rated aesthetically higher than nonsymmetric scarring, and our participants preferred maintenance of scar symmetry over preservation of native breast skin. These findings are consistent with previous studies that surveyed non-crowdsourced participants, which demonstrates the potential for crowdsourcing to be used to better understand the general public's preferences in plastic surgery.
