PRESERVATION, ULTRASONIC OR PIEZO-ELECTRIC RHINOPLASTY

Rhinoplasty techniques have undergone many modifications over time, piezoelectric techniques being some of the most recent. This form of rhinoplasty avoids hammers and chisels. Piezo-electric instruments can be used to cut, chisel and refine bones as well as cartilage without damaging the soft tissues.

It can improve precision and be gentle for soft tissues. Preservation rhinoplasty is done using the piezo electric instruments and tissues are reshaped and preserved and instead of being removed

1.The Device

The device uses high speed sound waves that cut by vibration employing tiny attachments of saws and other cutting and shaving inserts. The technique was first described in 2004 by Dr. Robiony and the instruments were FDA approved for this procedure in 2017

2.Advantages

Less swelling and more precise cuts. No splintering of tissues or bone fragments left behind.

It is especially advantageous for large and broad noses with humps and has the advantages of better precision in removing the humps and reducing the size, as well as preservation of soft tissues.

3.Indications

Patient selection is important for all rhinoplasties and the best candidates for piezo-electric technique are those with large noses. There is much less advantage of this technique in augmentation rhinoplasties.

4.Risks and complications

There are no additional risks for piezo- electric rhinoplasty other than the need for slightly more dissection of soft tissue for introducing the instruments. The bleeding and bruising is less than with traditional techniques but some swelling and bruising will still take place. The tissue swelling settles down sooner than with hammer and chisel rhinoplasty. Infections and other problems are possible though rare. It is hoped that the rate of revisions for rhinoplasty will also be less than traditional rhinoplasty.
