Abstract

A new technique is being discussed to correct the common skin sagging after classic liposuction. It concerns a combination therapy of an Nd: YAG laser system which brings laser impulses through a glass fiber probe into the fat tissue and thereby stimulates the production of collagen under the skin and a Titan infrared light system which briefly heats the subcutaneous tissue and thereby stimulates the collagen production in addition. The system is applied immediately after liposuction. This will prevent the skin slackening that occurs so frequently after surgery. The collagen induced by this combination therapy tends to contract over time and this gives a tighter skin and thus a more aesthetic result after liposuction.

Description

Description: "Tightening of subcutaneous tissues after liposuction"

Preface.

Liposuction or sucking away subcutaneous fatty tissue is currently one of the most performed aesthetic procedures. \ However, the problem remains the common skin relaxation after liposuction.

To prevent this defect, the subcutaneous tissues can be stimulated to tighten. Laser systems or infrared light therapy are used for this.

In the following, the updated 1064 nm Nd: Yag laser system is discussed in combination with an infrared light treatment (Titan) immediately after a liposuction.

The laser system.

It is a Neodynium: Ytrium Aluminum Granite laser system (DEKA Laser Italy) which produces a 1064 nm laser beam. The laser beam is inserted under ultra-short pulses (200 microsecond / pulse) through a 600 micron (previous version 300 micron) fiberglass under the skin to reach the fatty tissue. This is done at a pulse frequency of 40 Hz and an output of 450 mJ per pulse (previous version 250 mJ / pulse). The penetration into the soft tissues (such as fatty tissue) is 1.4 mm. This makes the effect local and does not cause remote trauma.

The laser effect is twofold and is known as a selective photothermolysis (both photomechanical and photothermal).

The photomechanical effect is the mechanical destruction of the fat cell as a result of the local heat development. The photothermal effect is the selective effect on the proteins of the fat cell membrane with necrosis and lysis of the fat cell.

A final effect of the laser energy is the induction of collagen under the skin. This connective tissue deposition gives, as a result, a visible skin retraction postoperatively.

A patent for this Nd: YAG laser system was taken on April 5, 2005 (MASOTTI LEONARDO under patent number W02006107522).

The laser system obtained a CE marking (CE 0459) in February 2004 and has been approved and recognized by the Food & Drug Administration ’in October 2006. _ The recently modified Nd: YAG laser system is more efficient and offers a maximum output of 18 Watt (previous system 10 Watt) with a maximum of 450 mJ / pulse.

The infrared light system (Titan).

The infrared light system was developed in 2004 by the company CUTERA (San Francisco, California, USA).

The lamp that is placed on the skin creates a warming of the subcutaneous tissues through infrared light (1100-1800 nm wavelength spectrum) that is absorbed by the water in these tissues. The energy released causes tissue warming and also a limited collagen denaturation. This results in a thickening and shortening of the collagen fibers with skin retraction as a result.

The Titan system obtained FDA recognition as "topical hearing for the purpose of elevating tissue temperature."

The former method.

The zone where the desired figure correction is to be made is first infiltrated under local anesthesia with a suitable solution (KLEIN solution).

This makes the fat tissue numb. This zone is then treated by the laser system. An incision of 1 mm is hereby provided through which the glass fiber cannula is introduced into the fatty tissue. After having supplied sufficient energy, the fat tissue can then be sucked away with a vacuum pump system.

However, the problem that already exists after liposuction is postoperative skin sagging. Certain areas of the body are also more sensitive to this skin slack (eg inner legs, lower abdomen, upper arms) and liposuction of these areas is therefore often against.

The new technology.

To prevent this postoperative skin sagging, the skin should be stimulated to produce collagen. This connective tissue product gives the skin a tighter and therefore a more aesthetic appearance. If after liposuction we can induce the skin to synthesize more collagen 5, a better, smoother postoperative result will inevitably be obtained.

And it is precisely this last that with the combination Nd: YAG laser system and infrared light therapy (Titan) I have been able to obtain according to a new technique.

The method of figure correction is as follows:

Ie infiltration of the relevant zone with KLEIN solution (1 liter of Physiological serum with 750 mg of Xylocaine, 1 mg of Adrenaline, 10 Meq NaBicarbonate) 2nd aspiration of the excess fatty tissue by liposuction. 3rd Nd: YAG laser system application under the skin to induce collagen production after liposuction. 4th Finally an application of the infrared lamp on the skin of the treated areas.

In the method described earlier, laser energy was used before the liposuction with much loss of this laser energy by the anesthetic solution.

In the technique that I described in the 2007-0288 patent, the fat tissue was first removed. The previous Nd: YAG laser system was then used to stimulate the subcutaneous tissue to produce collagen.

However, with this combination the desired skin retraction could not always be achieved.

However, by using the updated Nd: YAG system in combination with the Titan infrared therapy, the subcutaneous tissues at different levels and depths can be triggered for retraction.

Histological studies have shown that the Nd: Y AG laser system stimulates collagen production (resulting in skin retraction), coagulates small blood vessels (resulting in less blood loss and less bruising). There were no complications related to the laser system. ! ƒ The histological studies after infrared therapy show a thickening and shortening of the collagen bundles, resulting in tightening of the skin.

How is the energy brought into the subcutaneous tissues?

For the laser system: The 600 µm fiber optic (previously 300 µm system) that brings laser energy under the skin can be pushed through a spinal needle to the fiber optic tip just past the needle tip. A gentle pressure is applied to the skin with the finger of the other hand while the laser system sheds impulses into the subcutaneous tissue. The spinal needle (with the glass fiber probe at the end) is applied against the subcutaneous tissue at a speed of 1 cm / second in a continuous motion. The latter to avoid subcutaneous burns. During this movement, the laser system fires laser pulses at a frequency of 40 Hz and 450 mJ per pulse (previous system 150 mJ / pulse). The duration of laser energy application differs from zone to zone, but the following safe "average" is best used: Belly 2 minutes per side, Ruitersbroek 2 minutes, Flanks 2 minutes, Knee 2 minutes, Ann 3 minutes.

For the infrared system: before starting the infrared therapy, a gel is applied over the area to be treated. The tip of the infrared lamp is then placed against the skin and heated for up to 10 seconds. The treated area per pulse is 1.5 cm2. During the infrared treatment, the lamp must make discrete circular movements. It is recommended to repeat this process twice per area.

CONCLUSION. "Tightening of subcutaneous tissues after liposuction." Carrying out the combination Nd: YAG laser system with infrared light therapy after liposuction is a new addition to the figure correction possibilities that is best applied in combination with a liposculpture and this after the extraction of moisture and fatty tissue. The combination of these 2 techniques after liposuction has been performed is as yet unknown and offers numerous advantages. The practical implementation is described with the request to obtain a patent for "Tightening of subcutaneous tissues after liposuction." Performing this combination therapy has never been published before and has a number of important advantages: Ie Because there is less moisture and fat tissue present after liposuction, much more energy can be supplied to the skin. However, this energy has previously been absorbed to a large extent by the moisture and fatty tissue. However, if the latter is first sucked away, the effect of laser and light therapy on the skin and subcutaneous tissue is more pronounced. 2nd The combination of the laser system and the infrared system, each operating at a different depth level, will stimulate collagen production in addition to a greater skin retraction, which will benefit the aesthetic result. 3rd The small blood vessels in the skin can sometimes bleed a little at the end of the treatment. The laser therapy used in this situation results in a coagulation of these blood vessels with less blood loss and less bruising. 4th Correction of areas that were previously avoided because of the tendency to sag, can now be treated as a result of this more pronounced skin retraction. This is for example the case for the lower chin, inside of the upper legs or the upper arms. 5th After the liposuction the upper tissues are numb and the combination therapy Nd: YAG / Infrared will be experienced as painless. For the sake of 1.2, 3.4 and 5, the combination therapy Nd: YAG laser treatment and Infrared light therapy after a liposuction gives a better aesthetic result than when no laser / infrared treatment takes place or when the laser treatment takes place before the liposuction.
