Precision and Safety in Rhinoplasty: The Advancements and Challenges of the Piezoelectric Ultrasonic System

The introduction of the piezoelectric system in rhinoplasty, based on ultrasonic vibration with various tip shapes and sizes, has significantly enhanced surgical precision, safety, and protection of surrounding tissues. This innovative technique requires minimal pressure on the bone, even on mobile structures, thereby reducing the risk of unintended fractures. Wide exposure is necessary to optimize bone visualization, allowing for delicate rasping and contouring. The dorsal and lateral aesthetic lines can be sculpted with high accuracy using ultrasonic tips, preventing deformities and instability. However, the technique demands skilled and well-trained surgeons due to the fragility of the instrument, which is susceptible to breakage or malfunction.
