Nasal surgery with piezo is based on cutting the bone using microsound waves (ultrasonic). Piezo device does not cut soft tissues; it is designed to cut only bone tissue. Therefore, there is no chance of damaging the blood vessels. It is a method discovered by Tomaso Vercellotti. It has been used for years in various bone surgeries by neurosurgeons, maxillofacial surgeons and orthopedists. The use of Piezo in rhinoplasty operations is new.
The upper part of the nose is composed of bones. In almost all of the rhinoplasty surgeries, the nasal bones are intervened more or less.
In the classical method, the nasal bones are broken using a hammer-chisel. Although these fractures are made very meticulously with very special chisels, uncontrolled fractures can be seen from time to time in the classical method. On the other hand, in the classical method, bruises and swellings can be seen around the eyes due to damage to the soft tissue and blood vessels. However, the classical method is still the most preferred osteotomy method.
In piezo, bones are cut using ultrasonic sound waves. Piezo device is designed not to cut soft tissues, it only cuts bone tissue. If used properly, it is almost impossible to damage the vessel with Piezo. Therefore, vascular and soft tissue damage is significantly less with Piezo surgery, and postoperative swelling and bruises are seen in much lesser amounts. Since osteotomies are performed under direct vision in the piezo, uncontrolled fractures are not seen. Since the bone incisions are smooth, postoperative bone irregularities on the nasal dorsum are less common.
* “Piezo Surgery” mentioned in the text is the name of the method used. I do not have a commercial relationship with any company that markets the piezo surgical instrument.
