How does liposuction work?
What is liposuction?
Liposuction has become increasingly popular over the last decade and now stands among the most popular body-sculpting procedures. This increasing popularity is associated with the evolution of techniques and equipment for fat removal and body reshaping. Besides traditional suction-assisted lipoplasty, other options include ultrasound-assisted and external ultrasound-assisted liposuction, power-assisted liposuction, and laser lipolysis. Efforts in the search for alternatives and new tools primarily seek to reduce downtime, decrease operator fatigue, reduce bleeding, and promote skin contraction.
How dose 980nm laser lipolysis work?
980nm diode laser is used in continuous emission mode. Power settings are chosen as a function of the treated area: 6 W (chin, arms, knees), 10 W (abdomen, back), and 15 W (thighs, hips, buttocks). Transcutaneous illumination by the aiming beam ensures precise visualization of the region where the energy is delivered.The laser light is conveyed into the fat layer using a 1-mm microcannula which incorporates a 600-μm optical fiber. The microcannula has been specifically designed so that its distal end is level with the fiber tip. Also, the distal end is rounded to minimize potential tissue trauma resulting from the back-and-forth motion used.
To achieve optimal lipolysis, enough energy must be cumulatively delivered throughout the different fat layers (superficial, medium, and deep) and into the subdermal plane so as to reach the collagenous layer. Furthermore, a homogeneous distribution of light energy is required to get an optimal elevation of tissue temperature into the fat layer. This can be achieved only through optimal positioning and movement of the cannula during the procedure.
What is the result for liposuction ?
Both contour correction and skin retraction were observed almost immediately in most patients. There was no scarring, infection, burns, hypopigmentation, bruising, swelling, or edema. Ecchymoses were observed in almost all patients but were resolved in under 1 week in 322 patients. Only ten patients reported ecchymoses lasting 2 weeks and two patients reported ecchymoses lasting 3 weeks.
Who can do the lipolysis treatment ?
For each patient, age and sex were recorded. Contraindications to enrollment were as follows: pregnancy, bleeding disorders; immune deficits; heart, liver, and kidney insufficiency; allergies to local anesthetics; pacemaker and serious heart rhythm disorders; psychiatric disorders; unstable motivations; large fat volumes; and obesity.
This clinical study demonstrates that the removal of small volumes of fat with concurrent subdermal tissue contraction can be safely and effectively performed using a 980-nm diode laser. Additional benefits include excellent patient tolerance and quick recovery time. This study also confirms that enough accumulated energy must be delivered in order to achieve sufficient lipolysis throughout different fat layers.
