Body mass index and benign breast surgeries: A survey of plastic surgeons' knowledge and attitudes.

Background: The academic literature has not arrived at a consensus on the importance of body mass index (BMI) as an indicator of surgical feasibility and risk. This study evaluates board-certified plastic surgeons' and trainees' knowledge, experiences, and concerns around performing benign breast surgeries in high-BMI patients. Methods: An online survey instrument was developed and shared with plastic surgeons and plastic surgery trainees from December 2021 to January 2022. Results: There were 30 respondents (18 from Israel, 11 from the United States, and 1 from Turkey). For respondents who had BMI guidelines for performing benign breast surgeries, the median maximum BMI was 35 for all procedures. Most respondents supported or strongly supported their BMI guidelines.The majority of respondents indicated that they tended to have less training and experience in performing benign breast surgeries on high-BMI patients compared to those with BMI <30. Most respondents indicated that they were less satisfied with the results of these procedures on high-BMI patients compared to those with BMI <30. The median post-operation recovery time was indicated to be similar for high-BMI patients compared to those with BMI <30 across all procedures; however, the postoperative complication rate was indicated as higher. Conclusions: Respondents indicated that the risks of complication, more frequent need for surgical revisions, and unsatisfactory outcomes were their greatest concerns when conducting chest surgeries among high-BMI patients. Given that most surgeons practice in settings where high-BMI patients are excluded from procedure access, further research is needed to assess the extent to which these concerns reflect actual outcome differences.
