Abstract
PURPOSE: The piezoelectric device allows bone cutting without damaging the surrounding soft tissues. The purpose of this study was to assess the role of this surgical instrument in paediatric craniofacial surgery in terms of safety and surgical outcomes. METHODS: Thirteen consecutive paediatric patients underwent craniofacial Le Fort osteotomies type III and IV. The saw was used on the right side in seven patients and on the left side in six patients; the piezoelectric instrument was used on the right side in six patients and on the left side in seven patients. Intraoperative blood loss, surgical procedure length, incision precision, postoperative haematoma and swelling, and nerve impairment were evaluated to compare the outcomes of both procedures. RESULTS: A longer surgical procedure was observed in 28% of the patients when using the piezoelectric device (p = 0.032), with an intraoperative blood loss reduction of 18% (p = 0.156). Greater precision in bone cutting was reported, together with a reduction in the requirement to protect and incise adjacent soft tissues during piezoelectric osteotomies. There was a lower incidence of postoperative haematoma and swelling following piezo-osteotomy, and a significant reduction in postoperative nerve impairment (p = 0.002). CONCLUSIONS: The ultrasonic surgical device guaranteed a clean bone cut, preserving the integrity of the adjacent soft tissues beneath the bone. Although the time required for a piezoelectric osteotomy was longer, the total operation time remained approximately the same. In conclusion, the device's lack of power appears to be a minor problem compared with the advantages, and an ultrasonic device could be considered a valuable instrument for paediatric craniofacial advancement.
