Abstract

BACKGROUND: Aesthetic outcomes of unilateral cleft lip repairs have important psychosocial implications for patients who are heavily influenced by social perceptions. Online crowdsourcing offers the unique potential to efficiently recruit large numbers of laypeople to assess public perception. The aim of this study was to use the online crowdsourcing platform Mechanical Turk to compare the postoperative outcomes of Fisher, Millard, and Mohler cleft lip repair techniques.METHODS: Two hundred fifty-four participants were recruited through Mechanical Turk to evaluate 29 cropped and deidentified photographs of children, 8 photographs were controls without cleft lips and 21 were children with unilateral cleft lips who had undergone Fisher, Millard, or Mohler repairs (7 in each group). Respondents were asked whether a scar was present, whether they would be personally satisfied with the surgical result and used a Likert scale from 1 to 5 to rate overall appearance, scar severity, and nasal symmetry.RESULTS: Fewer respondents reported that a scar was present when assessing postoperative photographs of Fisher repairs (70.3 ± 8.6%) compared with Millard (92.0 ± 1.5%) or Mohler (88.8 ± 3.1%) repairs. Average rating of scar severity was also lower for Fisher (1.9) compared with Millard (2.6) or Mohler (2.6) repairs. Average ratings of nose symmetry, general appearance, and satisfaction with operative result were not statistically significantly different between the repair groups.CONCLUSIONS: This study demonstrates the potential of online crowdsourcing to assess public perception of plastic surgery outcomes. The Mechanical Turk platform offers a reduction in selection bias, ease of study design, and enhanced efficiency of large-scale participant recruitment. Results indicate that the Fisher repair led to the most favored aesthetic outcomes compared with the Millard and Mohler techniques, particularly with regard to scar severity. Crowdsourcing is a powerful tool to assess layperson perception of plastic surgery outcomes and can be used to better guide surgical decision-making.
