Background Microsurgery is a foundational plastic surgery principle. However, public unawareness of microsurgery and its associated rigorous training in the United States may contribute to current misconceptions and undervaluing of plastic and reconstructive surgeons. This study aims to characterize public knowledge of microsurgery.

Methods A cross-sectional survey was conducted from August to September 2021 using Amazon Mechanical Turk to assess baseline public knowledge of microsurgery. A multivariable logistic regression model was constructed to evaluate the association between baseline knowledge and demographic characteristics. Significance was set to a p < 0.05.

Results A total of 516 responses were analyzed. The mean age was 36.7 years (standard deviation, 16.04 years; white, 84%; non-Hispanic, 70%). Of those surveyed, 52% agreed that general surgeons perform microsurgery, while only 28% agreed that plastic and reconstructive surgeons perform microsurgery. When asked if head and neck reconstruction, breast reconstruction, and finger replantation required microsurgery, only 28, 41, and 41% of respondents agreed, respectively. When controlled for sociodemographic factors, Hispanics had significantly more odds to mistake that head and neck reconstruction did not require microsurgery (odds ratio [OR] 95% CI 0.49; 0.30–0.80; p = 0.004) and less odds to consider plastic and reconstructive surgeons for reconstruction (OR 0.51; 95% CI 0.32–0.84; p = 0.008). Females had 1.63 more odds of considering plastic and reconstructive surgeons for reconstruction (95% CI 1.09–2.43; p = 0.017). Low-educated participants had significantly more odds to consider general surgeons as those who performed reconstructive microsurgery (OR 8.70; 95% CI 1.09–69.40; p = 0.041).

Conclusion Misconceptions of microsurgery as a foundational principle of plastic surgery persist and correlate with undervaluing the specialty. Knowledge differs by ethnicity, level of education, and gender. Therefore, patient counseling should use culturally appropriate elements to demystify microsurgery, build value, and better inform risks and benefits.
