Piezo, or ultrasonic bone cutter or shaper is actually a controlled cutting or breaking method of bone. In the classical method, which has been used since the first years of modern rhinoplasty, uncontrolled fractures and cracks occurred while breaking the bone with chisel and hammer. People tried to prevent this, alternatively some surgeons started breaking or shaving bones with more gentle tools. At this stage, in parallel with technological developments, piezo, or ultrasonic bone cutter, emerged. We call the nasal aesthetics, which we shape the bone using this device, as Piezo Surgery, Ultrasonic Rhinoplasty.
