Abstract
Background: Although many patients who undergo reduction mammaplasty are obese, reports on whether obesity is a risk factor for postoperative complications have been conflicting. Objectives: This systematic literature review and meta-analysis aimed to evaluate the relationship between obesity and surgical complications after reduction mammaplasty. Methods: The PubMed, Medline, and Embase databases were searched between 1998 and 2016 using the MeSH terms and keywords “reduction mammoplasty (mammaplasty),” “breast reduction,” “obesity,” “body weight,” “body mass index,” and “risk factor.” Results: Among 26 studies that reported surgical complication risk and patient body weight, 11 concluded that obesity is not a risk factor and 15 reported that high body mass index increases surgical risk. On comparing obese and non-obese patients, we found that obese patients had a higher relative risk of surgical complications (1.38, 95% confidence interval 1.13-1.69), particularly skin and fat necrosis (2.01, 95% confidence interval 1.54-2.63). The pooled risk further increased with an increase in body mass index, and it was 1.71 for body mass index >35 kg/m2 and 2.05 for body mass index >40 kg/m2. Conclusions: Our meta-analysis indicated that the risk of surgical complications and tissue necrosis after reduction mammaplasty is higher in obese patients than in non-obese patients and that the risk gradually increases with an increase in the severity of obesity. The findings of this study could form a basis for preoperative patient education, surgical method selection, and determination of the extent of postoperative care.
