![]() Since then it has been widely utilized in a range of craniofacial applications including frontal sinus osteotomy, craniosynostosis, and Lefort osteotomies. The use of piezoelectric instrumentation (PEI) in bone surgery was then pioneered by Vercellotti 5 in 2004 who advocated its use for osteotomy and osteoplasty. The use of piezoelectric instruments in bony manipulation and consequent histologic assessment of bone healing was undertaken in a canine animal model by Horton et al 4 in 1975, demonstrating that the rate of bone healing measured through osteoblastic activity was higher in piezoelectric bony manipulation than bur hole manipulation. The frequencies and instruments can be optimized so that only the osseocartilaginous structures of the nose are affected, with the surrounding soft tissue remaining untouched. 2 This energy transduction is amplified and transferred to metal instrument inserts which can then apply this to organic tissue. The technology uses piezoelectric crystals and ceramics which deform mechanically when subjected to electric current. The ultrasound rhinoplasty technique utilizes oscillations of instruments at frequencies higher than that audible by the human ear: >20 kHz. In a market where >200,000 surgical rhinoplasties are performed annually in the United States, 1 there is a drive to improve and innovate this procedure, and outcompete fellow aesthetic surgeons by utilizing and perfecting pioneering techniques and technology. ![]() Piezoelectric “ultrasound” rhinoplasty has been rapidly growing in popularity. ![]()
