Soft Tissue · Procedure
Almost nobody comes to a revision consultation to say that too little was taken out. They come because of a ridge, a dent, or a step between the area that was treated and the area that was not. The problem is not volume. It is consistency across a surface — and consistency is a mechanical problem before it is a surgical one.
VIBROFIT is the answer to that half of the operation. Its cannula reciprocates over a very short distance at high frequency, so the instrument advances through the tissue under its own movement and the surgeon supplies direction rather than force. VASER decides what is possible close to the skin. This decides whether the surface it leaves behind holds together.
You are not choosing between VASER and VIBROFIT, and you will not be quoted for them separately. They are used together in almost every case here, and the fee is for the liposuction rather than for the equipment inside it.
This page exists because the two answer genuinely different questions, and because the question this one answers — will the surface be even? — is the one patients turn out to care most about afterwards. The ultrasound side is described on its own page →
The Problem
Liposuction is often imagined as a question of how much comes out. In practice the outcome is decided by something much less dramatic: whether the layer left behind has the same thickness everywhere it should.
Removing fat by hand alone depends entirely on the surgeon’s movement — the speed of each pass, the angle, the force behind it. Over a small, detailed area that dependence is an advantage, because a hand is more responsive than a machine. Over a broad one it is the origin of unevenness, because no hand keeps a perfectly constant rhythm for an hour.
A surface records that inconsistency faithfully, and it does so in a way that only becomes visible weeks later, once swelling has gone. By then the tissue has healed to the shape it was left in.
Contour irregularity is the characteristic complication of liposuction, and in the largest published series of ultrasound-assisted cases it was also the most common one — 1.9 per cent across 783 treated areas, more frequent than seroma, infection or pigment change.[1]
It is also the hardest to undo. Correcting a dent means putting contour back, which is grafting rather than suction, and grafted fat into scarred tissue is a less predictable proposition than not having created the dent. This is the specific reason the instrument used for removal is worth a page of its own.
Mechanism
VIBROFIT is a powered liposuction system. Its cannula reciprocates — travelling back and forth over a very short excursion, many times a second — so that the tip is always in motion relative to the tissue even when the surgeon’s hand is nearly still.
The practical consequence is a change in what the surgeon has to supply. With a static cannula the arm provides both the direction and the force; with a reciprocating one the instrument advances itself, and the arm provides direction alone. Fat is loosened by the movement of the cannula rather than torn away by a push.
Two things follow from that, and only one of them is about the surgeon.
Neither of those is glamorous. Both of them are the difference between a technically correct result and one that also looks correct at six months.
Technique
Aspiration descends through the subcutaneous layers rather than treating them as one mass. The order is not stylistic, and neither is the diameter used at each level.
Using a cannula sized for the deep layer close to the skin. It is quicker, it removes more per pass, and it produces precisely the ridge or dent that brings a patient to a revision consultation.
Descending diameter is not a preference or a signature. It is the mechanical reason a superficial layer survives being worked at all.
Access is planned so that each area can be reached from more than one direction. A layer worked from a single angle carries the signature of that angle in the surface, in the form of faint parallel lines that appear only once swelling resolves. Crossing the passes from two directions is how that is prevented, and it is a reason ports are placed for geometry as well as for concealment.
Thickness is then checked by pinch rather than by eye, and compared with the same point on the other side. A body that is supine, infiltrated and swollen does not look symmetrical even when it is; between finger and thumb, it can be measured.
Application
Broad areas
The larger the treated surface, the more of the result is decided by consistency rather than by quantity. These are the areas where a constant mechanical rhythm is not a refinement but the whole argument, and where hand-only technique is most likely to leave a visible transition at the border.
Circumferential work
A 360-degree case is treated in two positions, and the join between what was done supine and what was done prone is the place a step most often appears. Reproducible removal on both sides of that join is a mechanical requirement, not an aesthetic preference.
Volume
Where a great deal is being removed, the case is long and the last hour matters as much as the first. This is where the difference between an instrument that advances itself and an arm that has been working for three hours becomes something the surface can record.
Fat that is being kept
Where fat is being moved rather than discarded — to the breasts, hips or pectorals — how it is removed is no longer only a contour question. Gentler mechanical handling of tissue intended to survive elsewhere is the reason harvest technique is planned alongside the grafting itself.
Evidence
We would rather be direct about this than let a technology page imply more than the literature supports.
Ultrasound-assisted liposuction has been compared head to head against conventional liposuction in randomised, blinded trials, and those results are set out on the VASER page — including the two recent studies that failed to reproduce them.
Power assistance has not been subjected to the same scrutiny. There is no equivalent trial we can cite, and we are not going to dress a mechanical argument as an evidential one. What we can say is what the mechanism is, why it addresses the complication that actually occurs, and what that complication rate looks like in practice.
The one figure worth putting in front of you is the complication profile of modern liposuction generally. In a single-surgeon series of 261 patients across 783 treated areas followed for a minimum of six months, the overall complication rate was 4.6 per cent, and the breakdown is the relevant part:[1]
| Complication | Rate |
|---|---|
| Contour irregularity | 1.9% |
| Seroma | 0.8% |
| Cellulitis | 0.8% |
| Pigmentation change | 0.4% |
| Electrolyte imbalance | 0.4% |
These figures describe a published study population, not results at this practice, and they are not a prediction of your individual outcome. Full citations are at the foot of this page.
Read the table for what it is. The risk of this operation is not catastrophe; it is the surface. Contour irregularity is more common than every other complication on that list, and it is the one thing a patient sees every day afterwards. An instrument whose entire contribution is consistency across a surface is addressing the most likely thing to go wrong — which is a better argument for it than a marketing claim would be.
Candidacy
Which instrument leads in your case is a decision made from the area and the design, at consultation, rather than something you need to specify in advance. If a plan would be better served without it, that is what you will be told.
Recovery
Removing volume leaves the overlying skin with more surface area than it needs. Compression is how that skin is guided back onto the new contour — it is not a comfort measure, and it is not optional.
Everything on this page about achieving an even plane in theatre can be undone in the six weeks afterwards. Abandoning the garment early is one of the more common reasons a technically good result reads as irregular at three months.
Fees
The fee is for the liposuction, not for the instrument used inside it. Whether ultrasound, power assistance or both are used in your case does not change the figure. Charged by area, in Japanese yen and including consumption tax; treating several areas is quoted as a combination rather than a simple sum.

Guarantee
VASER liposuction and VASER 4D carry a guarantee for one year after surgery, and that covers the liposuction as we perform it — including the power-assisted removal within it. We mention it here rather than in the small print because for a patient travelling from abroad it changes the calculation.
Being outside Japan does not void the guarantee, but making use of it means returning to Japan. Please plan on that basis rather than assuming otherwise.
Risks
This is elective surgery, it is not covered by health insurance in Japan, and its outcome cannot be guaranteed. A powered cannula reduces neither the list below nor the need to read it.
Questions
It is a powered liposuction system whose cannula moves back and forth by itself, over a very short distance and at high frequency. The technique is called power-assisted liposuction, or PAL. The cannula still has to be steered, but it advances through the tissue under its own movement rather than being pushed. What that changes is not the amount removed. It is how consistent the removal is across a surface.
Because separating fat and removing it are two different problems. VASER emulsifies the fat but takes nothing out; it is a solid probe. Something then has to aspirate the released layer, and over a broad area the difficulty is no longer whether the fat will come out but whether it comes out evenly. A powered cannula holds a constant rhythm for an hour. A hand does not.
In mechanism, it is ordinary liposuction with the cannula doing the reciprocating instead of the arm. That sounds like a small difference and over a small area it is. Over a large one it is the difference between a surface that is uniform and one that records every variation in the force applied to it. Nobody complains about a technique on a small area. The complaints come from big ones.
A ridge, a dent, or a visible step between a treated area and an untreated one. It is the characteristic complication of this operation and the reason patients seek revision, and it is far more common as a complaint than being told too little was removed. It is also considerably harder to correct than to avoid, because adding contour back means grafting rather than suction.
Yes, and it is one of the few things on this page that is not a matter of judgement. The deep layer is taken first with a larger bore, because that is where volume lives and the skin is furthest from harm. The superficial layer is approached last with the smallest cannula, its openings turned away from the skin. A cannula sized for the deep layer, used close to the dermis, produces exactly the irregularity described above.
Not in the way there is for ultrasound, and we would rather say so. Ultrasound-assisted liposuction has been compared against conventional liposuction in randomised trials. Power assistance has not been subjected to the same scrutiny, so there is no trial we can point you to. The case for it is mechanical and practical rather than evidential, and presenting it as anything more would be dishonest.
Rarely. In most cases the fat is separated with ultrasound first and then removed with the powered cannula, because each instrument answers half of the problem. Where an area is soft, broad and requires no detailed work close to the skin, power-assisted removal alone can be appropriate. That is decided at consultation from the area and the design, not in advance.
Plan for at least two weeks after surgery. That period covers early recovery, compression management and at least one in-person follow-up before you are cleared to fly. Your arrival date before surgery is set separately in your written plan.
The fee is for the liposuction, not for the instrument. It is charged by area, from 275,000 yen per area including tax; the complete abdomen is 770,000 yen. General anaesthesia, the standard post-operative set and blood tests are additional, and a surcharge applies by body mass index. Whether ultrasound, power assistance or both are used in your case does not change the figure.
Yes. VASER liposuction and VASER 4D carry a guarantee for one year after surgery, and that covers the liposuction as performed here regardless of which instruments were used within it. It includes re-examination by your operating surgeon at no consultation charge, post-operative treatment, and design adjustment from six months at the surgeon’s discretion. Using it means returning to Japan.
