Powered and Piezoelectric Rhinoplasty Techniques

Power-assisted rhinoplasty relies on motor-driven tools to shape and cut the nasal bones, and specifically, piezoelectric devices use ultrasonic frequency vibration to perform these bony modifications while minimizing damage to the surrounding soft tissue or cartilage. Primary uses of these techniques include reducing bony dorsal humps, addressing bony asymmetries, and performing osteotomies. Compared with manual techniques, powered rhinoplasty allows for more precise and atraumatic cutting or rasping of the bone. Piezoelectric instruments are emerging as more favored, as their atraumatic handling of surrounding tissue allows for expanded applications compared to powered techniques, such as complete exposure of the nasal vault to perform lateral and complete osteotomies under direct visualization, precise ostectomy, sculpting of mobilized nasal bones, which also facilitated the resurgence of dorsal preservation rhinoplasty techniques.
