A recent study published in the Aesthetic Surgery Journal (September 2018) revealed that tissue liquefaction liposuction (TLL, Hydrasolve, Andrew Technologies) extracts fat more quickly with less arm movement than traditional suction-assisted liposuction (SAL). TLL patients also experienced less bruising and swelling post treatment. Researchers Joseph P. Hunstad, MD, FACS, et al, performed a contralateral study with 31 adult female subjects. They compared surgical efficiency, lipoaspirate, and differences in bruising, swelling, tenderness and incision appearance ratings between TLL and SAL procedures.
The average volumes of infusion (1.242 L for TLL vs. 1.276 L for SAL) and aspirated supernatant fat (704 mL for TLL vs. 649 mL for SAL) were statistically similar. The median fat extraction rate with TLL was faster than SAL (35.6 mL/min vs. 25 mL/min) and stroke rate was reduced in TLL vs. SAL procedures (48 strokes/min vs. 120 strokes/min). The TLL-treated side had lower mean total scores for bruising, swelling, treatment site tenderness and incision appearance post treatment.
