Background
Breast hypertrophy causes physical and psychological symptoms. Reduction mammaplasty is a surgical procedure to lessen discomfort. However, there is a dispute about whether the weight of breast resection is related to body weight. This study aims to provide Chinese data and assess the association between body weight and removed weight in women undergoing reduction mammaplasty.
Methods
Retrospective data were collected from 1777 breasts in a single center in 17 years. Simple linear regression analysis was performed to establish whether removed weight and removed weight ratio (removed weight/body weight) correlated with the body weight. The correlations were then analyzed again after grouping according to the removed weight.
Results
For all breasts included, removed weight or ratio positively correlates with body weight. When the removed weight is more than 1000g, there is no statistically significant correlation between body weight and removed breast weight. When removed per breast weight is more than 600g, there is no correlation between body weight and removed breast weight ratio.
Conclusions
The correlation between body weight and removed weight or ratio decreased with increasing removed weight. When removed weight >600g, the degree of breast hypertrophy is not related to body shape.
