ABSTRACT

Significant advancements in liposuction have resulted from changes found in machinery or instrumentation. In the future, the most significant advancements will be the specialized type of solutions injected into the fat. The hypotonic pharmacological lipo-dissolution (HPL) technique is the dissolution of fat by: (1) the use of a two-step injection of a barrier-vasocon-strictive and then a hypotonic-pharmacologically active set of solutions to sensitize and swell the fat cell; (2) the use of focused, bivectorized, external ultrasonic energy to dislodge and ultimately rupture the fat cells (which also appears to assist in skin contraction). In small fatty deposits of ≤250 mL, the dislodged and ruptured lipocytic cell contents are absorbed, and no suctioning is necessary. For larger fatty deposits, up to 6,000 mL, small cannula suctioning of the emulsified fat has been performed. The combination of external ultrasound and microcannula liposuction appears to offer improved dermal skin contraction.
