ABSTRACT
BACKGROUND: There are few objective techniques to accurately measure the outcome of liposuction. Consequently, there is also a paucity of data quantifying the results of this procedure. OBJECTIVES: The authors compare changes in abdominal volume and circumference with several objective measurement techniques in a relatively homogeneous group of individuals undergoing liposuction in a single, defined abdominal region. METHODS: This clinical study enrolled 23 patients with a body mass index (BMI) <25 kg/m(2) who had a localized anterior abdominal contour defect. Patients underwent standard suction-assisted tumescent liposuction. Changes in abdominal volume and circumference in the operative area (60 mm above to 80 mm below the umbilicus) preoperatively and 10 weeks postoperatively were assessed using a 3-dimensional (3D) digital photographic system and a standardized constant-tension manual tape measure procedure. RESULTS: The majority of the patients in this study were Caucasian women with a mean age of 42 years, a mean weight of 65.8 kg, and a mean BMI of 23.8 kg/m(2). In the study population, mean abdominal volume and umbilical circumference were reduced by 231.0 mL (~30% of subcutaneous fat) and 1.7 cm, respectively, at 10 weeks postoperatively as determined by 3D digital imaging. Fat volume in the surgical aspirate (mean = -183.3 mL) was a poor predictor of individual outcome, as assessed 10 weeks postoperatively by both the 3D digital imaging and multilevel constant-tension tape measure assessment tools. CONCLUSIONS: Both 3D digital photographic imaging and a standardized manual tape measurement procedure proved to be reliable tools for objectively assessing changes in abdominal circumference and volume produced by standard liposuction of a single, defined abdominal region.
