What it is exactly
It is a rhinoplasty in which the work on the bone is done with piezoelectric instruments. The approach, dissection, management of the tip, sutures and closure do not change.
The instrument vibrates at a very high frequency with a very small amplitude. That vibration breaks up bone, which is mineralised tissue, and does not have enough energy to cut soft tissue. In theatre this means the tip of the instrument can rest on the mucosa, a vessel or cartilage without damaging them, and the bone can be worked on under direct view when the approach exposes it.
Compared with the conventional technique
The difference lies in the degree of control during the bone work and in the trauma to the surrounding tissues.

General trends. Bone healing and the stabilisation of the result follow their own pace, which is a matter of months, with any instrument.
The conventional technique has decades of results behind it and works well in experienced hands. Between a surgeon with sound judgement using a chisel and one without it using ultrasound, the first almost always does better. The instrument widens what a good surgeon can do and does not make up for what is missing.
Which noses it helps and which it does not
The benefit is proportional to the amount of bone work the case needs.
Where it adds more
A marked bony hump, wide dorsums that need narrowing with symmetrical osteotomies, fine corrections of irregularities or asymmetries of the dorsum, thin or fragile bones, deviations of the bony pyramid and revision rhinoplasty, on bone that has already been operated on.
Where it adds little
When surgery focuses on the tip (projection, rotation, definition), in cartilage-only corrections, when the bone barely needs touching or when the aim is functional and lies in the septum. In those cases the ultrasonic technique adds theatre time without a proportional benefit.
Preservation and dorsal recycling
Preservation rhinoplasty aims to keep the nose's own structures, such as the dorsum, ligaments and support, instead of removing and rebuilding them. It is often combined with ultrasonic instruments, which allow the bone to be modified without taking the dorsum apart. It complements the classic techniques and has specific indications.
In suitable cases Dr. Verbauvede uses dorsal recycling: the bone and cartilage removed when lowering the profile are kept and reused as grafts in the same nose. The surgery works with the patient's own tissue without turning to other donor sites when that is not needed, and the precision of the piezoelectric cut makes it easier to obtain usable fragments.
What the ultrasonic technique does not do
-
It does not turn a difficult nose into an easy one: a very deviated pyramid, very thick skin or weak cartilage remain the same problem.
-
It does not improve the work on the tip, which is cartilage and soft tissue.
-
It does not shorten the real recovery. It improves how the first days look more often than the conventional technique, and the time to the final result is still a matter of months.
-
It does not remove the risks of nasal surgery: asymmetries, irregularities of the dorsum, breathing problems and the need for a touch-up.
How the nose changes
The first month has the most swelling and the nose looks wide. Between the third and sixth months much of the definition appears. The tip is the last to settle, and the result is considered stable between twelve and eighteen months depending on the thickness of the skin.
Frequently asked questions
How is it different from a conventional rhinoplasty?
In how the bone is worked on. The conventional technique uses a chisel and rasp; the ultrasonic one, a piezoelectric instrument that only acts on hard tissue. This allows the dorsum to be shaped more gradually and the soft tissues to be spared. The rest of the surgery is equivalent.
Does it hurt less or is recovery faster?
It is common to see less bruising around the eyes and more contained early swelling. It does not shorten the time the result takes to mature, which is measured in months, nor does it avoid the postoperative period. The difference shows mainly in the first two weeks.
What is preservation rhinoplasty?
An approach that keeps the natural structures of the nose, such as the dorsum, ligaments and support, instead of removing and rebuilding them. It is often combined with ultrasonic instruments and complements the classic techniques.
Can every nose be operated on with this technique?
No. It is useful with a bony hump, asymmetries of the dorsum or deviations that call for fine work on the bone. If the problem is in the tip, the cartilage or the septum, it adds little and the right technique is a different one.
Does it carry more risks than the conventional technique?
It shares the risks of any rhinoplasty: bleeding, infection, irregularities of the dorsum, breathing problems and results that may need revision. What it adds is more precise control of the bone cut, which depends on the surgeon's experience with the instruments.
How much time off work is needed?
The approximate timescales are similar with both techniques: splint for about a week and a gradual return to activity a few days later. Where there is a difference, it is in how the eyelids look in the first week.
