Ultrasonic Rhinoplasty

Two things, both under direct vision. A bony hump is reduced by shaving it down gradually with a vibrating tip, the way a fine rasp would work if it could not tear anything, and the edges are smoothed as the surgeon goes. Then the nasal bones are cut along planned lines, either to move them inward after a hump has been removed or to correct a deviation or asymmetry. In a conventional operation those cuts are made blind with a chisel and mallet through a small stab incision, and the fracture goes where the bone lets it. With the piezoelectric instrument the cut goes exactly where it was drawn.

At the frequencies and settings used in rhinoplasty the tip cuts mineralised tissue and tends not to cut the soft tissue immediately around it: the lining of the nose, the small vessels, the skin envelope. That selectivity is the whole reason to use it. Less injury to the vessels means less bleeding into the tissues, which is why the bruising around the eyes is lighter, and less injury to the lining means less swelling inside the nose in the first week.

The instrument has to be applied to bare bone with the surgeon watching, so the skin and soft tissue are lifted off the bony vault more widely than a conventional osteotomy requires. That is done through an open approach, with a small incision across the columella that fades to a fine line. For most patients that is a fair trade for precision. For a case that needs only a minimal, well-placed conventional osteotomy, it may not be, and that is one of the reasons the instrument is not used on every nose.

No, though they are often used together. Preservation rhinoplasty is a strategy: keeping the natural dorsum intact and lowering it as one piece rather than removing the hump and rebuilding the bridge. Ultrasonic rhinoplasty is an instrument: a way of cutting bone precisely. Preservation depends on fine bone work at the base of the bony vault, which is exactly where the piezoelectric instrument is at its best, so most preservation cases here are also ultrasonic cases. The reverse is not true. Ultrasonic instruments are used just as often in structural rhinoplasty and in revision.

Often, and in a specific way. A common leftover from a previous operation is a bony irregularity: a residual hump, a visible edge where the bones were fractured unevenly, or an open roof where the bones never came together. Shaving and recontouring that bone under direct vision, without new fractures propagating through scarred tissue, is what the instrument does well. It does not solve the cartilage and skin problems that make most revisions difficult; those are addressed with grafting and the rest of the revision plan.

Somewhat. The instrument works gradually, and the wider exposure adds time, so three to four hours is typical against a somewhat shorter conventional operation for the same nose. The added time is spent on precision, not on recovery: patients typically go home the same day, and the first week is, if anything, easier because of the reduced bruising.

The bony contour set at surgery is the one that stays; bone does not swell and settle the way cartilage and skin do, so what is shaped precisely tends to look precise at twelve months and beyond. Where it may matter more is in avoiding the small irregularities and steps that a blind fracture can leave and that thin skin reveals years later. The rest of the result ages as any rhinoplasty does, with the face.

The general risks of rhinoplasty apply: bleeding, infection, asymmetry, temporary numbness of the tip and upper lip, and the rare need for revision. The instrument itself adds a learning curve for the surgeon rather than a new risk for the patient. Used badly it can generate heat or over-thin the bone, which is a matter of training and experience; used well, the incidence of irregularity and asymmetry is lower than with conventional osteotomies, not higher. Dr. Saman has used piezoelectric instrumentation for years and teaches it to visiting surgeons.

Because it is slower, because it requires wider exposure than a percutaneous osteotomy, and because it has a real learning curve; the results in a surgeon’s first cases are not the results in their hundredth. Those are legitimate reasons, and a surgeon who does excellent bone work with conventional instruments is not behind the times. What matters is that the surgeon can explain the choice for your nose. A surgeon who describes their entire approach as ultrasonic rhinoplasty is naming their saw; it is worth asking what they intend to do with it.

You often cannot tell from the mirror, which is why the examination matters. A hump can be bone, cartilage, or a combination that changes along its length; the bony part is usually the upper third. Wide or deviated nasal bones are a bony problem. A bulbous or drooping tip, wide nostrils, or a nose that projects too far are cartilage problems, and the instrument has little to offer them. The consultation sorts your concerns into the two piles, and the plan follows from that rather than from the name of a device.
