Piezo is the name of a specialized device used in rhinoplasty (nose aesthetics) surgeries. The procedure performed using this device is called 'Ultrasonic Rhinoplasty with Piezo Method'. It is a modern technique that has gained particular popularity in the last 8-10 years. Essentially, the Piezo device uses ultrasonic sound waves to precisely reshape bones, offering a more controlled and minimally invasive approach.
