Fat Disruption : A Useful Adjunct To Liposuction Surgeryby

Fat disruption concept l.jpg

Fat Disruption Concept

  • Not a new idea

  • Chopped up fat is easier to suck out

  • UAL (Ultrasound Assisted Liposuction)

    • Fat disruption before liposuction

    • Great in tough areas (scar, gynecomastia)

    • Made aspiration easier

    • Cost

Fat disruption concept3 l.jpg

Fat Disruption Concept

  • Blugerman liposhifting instrument

    • Introduced in 2002 Liposuction World Congress

    • Designed to create mini fat grafts internally

    • in vivo fat grafts manually shifted to fill defect

    • Solid core cannula 3-4mm diameter

  • Current concept

    • Mechanical disruption of fat infrastructure

    • Not intended for fat grafting

    • Detach the fat from its stroma before suction

    • Uses much larger cannulas: 5-6mm typical

Advantage of fat disruption l.jpg

Advantage of Fat Disruption


    • Rapid volume reduction

    • Aspiration speeds up to 1000ml/min

    • Large cannulas do not cause irregularities

  • Smooth results regardless of cannula size

    • No suction applied during disruption

    • Even superficial passes do not leave divots

  • Especially useful for:

    • Large volume reduction

    • Beginning liposuction surgeons

Prototype fat disruptor instrument and technique l.jpg

Prototype Fat Disruptor Instrument and technique

  • Large sizes: 5 & 6mm empirically work the best

  • Hollow cannulas

    • Relieve tumescent pressure

    • Retains leaking aspirate in hose; less mess

  • Fat disruption surface

    • Not designed for fat grafting

    • Longer, larger holes, faster

    • Push and pull disruption more efficient

Fat disruption technique l.jpg

Fat Disruption Technique

  • Large tumescent volume

  • No suction used in disruption phase

  • No divots, no ridges, no depressions

  • Different than pre-tunneling

Technical notes l.jpg

Technical Notes

  • Intense “super” tumescence - high hydrostatic pressure

    • Forced fluid dispersion

    • Hydrostatic capillary compression

    • Bloodless

  • Staged tumescence – infuse in staged areas e.g.

    • Front the Back

    • Upper body then lower body

    • Vasoconstriction last only ~90min

    • Speed critical for larger volumes

Technical notes8 l.jpg

Technical Notes

Tumescent Solutions Compositions

  • Lidocaine = .048% (50ml 1% lidocaine in 1L)

  • Epinephrine = 1:1,000,000 (1ml 1:1000 epi in 1L)

  • Max dose 40-50mg/Kg

  • Addition tumescence above the max lidocaine dosages had no lidocaine. Only:

    1:1,000,000 epi in LRS

Slide9 l.jpg

Large fat disruption surface

Intense tumescence

Note firm tissue turgor

No suction applied yet

Start deep next to muscle

5-6 minutes, loss of resistance

Slide10 l.jpg

Able to get close to surface

No surface defects

Begin 60 secs of suction

Large 6mm cannula

Note free flow of aspirate

1000ml in 60 seconds!

Greater cosmetic safety useful in defects prone areas l.jpg

Greater Cosmetic SafetyUseful In Defects Prone Areas

High Resistance Areas

  • Gynecomastia

  • Epigastrium

  • Upper back

  • Revision liposuction

Greater cosmetic safety l.jpg

Greater Cosmetic Safety

For Experience Surgeons

  • SPEED!

  • Significantly shorter procedures

  • Greater time for refinement

  • Cost-effectiveness

Greater cosmetic safety13 l.jpg

Greater Cosmetic Safety

For Beginning Surgeons

  • Much shorter learning curve

  • Reproducibly smoother results

  • SPEED!

  • Cost effective

Fat disruption summary l.jpg

Fat Disruption Summary

Great Speed & Smoother Results

  • Shorter procedure times

  • Less blood loss

  • Less anesthesia

  • Less expense

    Greater Patient Safety
