Restoration Liposuction of the Abdomen: High-Definition Liposuction With Umbilicus and Lower Abdomen Improvement Using Polydioxanone Threads.

BACKGROUND

Abdominal high-definition liposuction has been practiced for many years. However, problems such as low-lying, "sad-looking" umbilici and lower abdominal "pooches" remain unresolved. Additionally, the waistline, as the pivotal point connecting the chest and hips, deserves more attention and improvement.

OBJECTIVES

The aim of this study was to use polydioxanone (PDO) threads after liposuction: (1) to improve the shape and position of the umbilicus permanently; (2) to tighten the lower abdomen permanently; and (3) to redefine "high-definition" liposuction.

METHODS

All patients underwent high-definition liposuction of the abdomen and waist. After liposuction, bidirectional, barbed PDO threads were placed in the upper central abdomen. The threads were pulled to cinch the upper abdominal skin and then tied. The resulting umbilicus elevation was measured for up to 12 months. Higher waistlines were also created to match higher-positioned umbilici.

RESULTS

Fifty-two female subjects were included. The range of umbilicus elevation at 12 months was 0.8 to 3.6 cm. Most umbilici were converted to vertical orientation, and lower abdomens became lengthened, flattened, and tightened. Moreover, the enhanced waistlines and body curves created better body proportions.

CONCLUSIONS

This technique results in permanent elevation and shape enhancement of both umbilicus and lower abdomen. In addition, because the umbilicus is raised, a higher waistline can be created without any discordance, making the lower limbs appear longer. Overall, the maneuvers contributed to the restoration/rejuvenation of the abdomen and created a better overall body shape and proportion.
