Abstract

BACKGROUND:

Hydrolipoclasy is an alternative technique less invasive than liposuction. Hydrolipoclasy uses normal saline or hypotonic solution and ultrasound waves that act directly on local adiposity. In the literature there are few reports of morphostructural changes on adipose tissue.

MATERIALS AND METHODS:

This study was aimed to evaluate the amount of fat cells injured immediately after treatment and after three days and also cell migration to the area treated using 8 pigs as experimental models, as well as cellular changes by transmission electron microscopy (TEM).

RESULTS:

The Wilcoxon test was conducted, and a difference was found between the treated side and the corresponding control side on the number of viable cells. The treated side showed a smaller number of viable cells compared to the control side both immediately after treatment and 3 days later. Also occurring 3 days after treatment was the migration of lymphoid cells and fibroblasts, which shows the local inflammatory process and conjunctive neoformation. Soon after treatment there was fluid accumulation within adipocytes.

CONCLUSIONS:

The results shown in this paper demonstrate Ultrasonic Hydrolipoclasy as a viable alternative for the treatment of localized fat deposits without the side effects of traditional surgical procedures. Better results are expected when hypotonic solution is used, since it penetrates into the cell.
