Piezoelectricity is a physical phenomenon, right out of your science textbook. It’s a two-way street: it describes an electrical current that can be generated from motion, or vice versa, motion that can be created from a current. The latter is where the magic lies. Electricity is used to produce a very specific type of motion: a high-frequency ultrasonic pulse. The frequency of these vibrations is tuned so precisely that it affects only mineralized tissue, meaning bone.

The key distinction is selectivity. The tip affects bone and not the surrounding soft tissue. You can run the piezo against your skin and nothing happens. Touch it to bone, and it does its thing. The device comes with several tip configurations: saws, rasps, drills, different shapes and angles, one for every need.

The advantage is twofold. First, it enables the surgeon to be highly precise and intentional with bone work. The tip affects bone methodically. Interestingly, the piezo actually works less efficiently if you press too hard. There’s a fine touch at which the vibrations perform best, which builds in an element of control that is ideal. Second, the adjacent soft tissues, of which there are many in very tight quarters, remain unaffected. Beneath the nasal bones lie mucosa and blood vessels. Chisels and rasps don’t discriminate and can pierce these tissues, causing small tears and bleeding: a headache intraoperatively, and more bruising postoperatively. The piezo induces less trauma while being more controlled, and it comes with less bruising.

The most visible difference is in the first week after surgery. Patients who undergo rhinoplasty with the ultrasonic technique typically have significantly less periorbital and cheek bruising, the dark discoloration under the eyes that most people associate with nose surgery. Swelling is still present, as it always is, but recovery tends to be more manageable and less socially limiting. By five to seven days most patients have a yellowish tint to the cheeks, and much of that is gone by ten to fourteen days.

This isn’t anecdotal. I conducted a prospective randomized study comparing the piezoelectric device to a conventional chisel in rhinoplasty patients. These patients consented to the study, and we used the chisel on one side of the nose and the piezo on the other, with the side determined by randomization. The results showed a statistically significant reduction in bruising on the piezo side, with a p-value below 0.01. The study was published in the American Journal of Otolaryngology in 2023.

In the same study, we also found that the piezo side may have slightly more swelling than the chisel side, even with less colored bruising. The reason is mechanical: you can’t bury the piezo under the skin the way you can a chisel. The skin has to be elevated off the bone to create a working window, and that elevation alone can cause some swelling. It also takes a bit more time. But empirically, my experience is that the additional swelling isn’t meaningfully more, and over the years I’ve found ways to reduce it further.

Like everything in surgery, there are many reasons. We learn technique from those who trained us, and we employ what we’re comfortable with. I was fortunate to be trained with both the chisel and the piezo. I’ve done a significant number of cases in hospital settings where a piezo wasn’t available, so I’m genuinely comfortable with chisels. But surgeons without piezo exposure may simply not have had the opportunity to learn its benefits. And you can’t overlook cost. The device itself is a significant investment, and maintenance and tip replacements factor into the economics. That said, as someone who performs a high volume of rhinoplasty, I’d say the piezo is nearly irreplaceable. Chisels cannot match its capabilities.

Beyond recovery, it truly matters in the results. The ultrasonic device offers a level of precision that conventional instruments simply can’t match, and it goes beyond cosmetics.

In cosmetic rhinoplasty, the advantage is almost self-explanatory. A paintbrush for the bone. Gentle, intentional. Fine contouring, narrowing the bridge.

I also use it to stabilize the nose when needed. Sometimes you open a rhinoplasty expecting a straightforward change and encounter something more complex, an unexpected undulation that calls for a small reconstruction. The piezo lets me cut precise grooves to seat grafts and drill accurate holes to fix them in place.

For revision cases, reconstructive work, and functional breathing surgery, using the piezo to secure grafts to stable bone is invaluable. I use it during septoplasty to reduce bony undulations atraumatically. It is, without question, the tool I want available in any nasal surgery.
