Background:
There is a lack of convenient and accurate objective methods to evaluate the clinical efficacy of thigh liposuction.
Methods:
This retrospective study involved the 3-dimensional images of 19 patients who underwent bilateral thigh liposuction. Data such as volume change and volume change rate before and after surgery, circumference change, and circumference change rate of 3 planes (upper, middle, and lower) were analyzed. The correlation between body mass index and volume change rate and between preoperative circumference and circumference change rate of different planes were determined.
Results:
There were significant differences between the preoperative and postoperative volume and circumference of 3 planes of 19 patients (38 thighs). The rate of change in total volume (16.90 ± 5.55%) correlated with the circumference change rate at the top of the thigh. There was also a linear relationship between body mass index and volume change rate, but not between preoperative circumference and circumference change rate.
Conclusions:
Three-dimensional imaging technology can accurately quantify the volume and circumference change of the thigh to objectively evaluate the clinical efficacy of thigh liposuction.
