Abstract: The aim of the study was to compare in a randomizedcontrolled clinical trial the use of the piezoelectric osteotomy as analternative to the conventional approach in terms of surgery time,intraoperative blood loss, cut quality, nerve injury, and costs.One hundred ten patients who had orthognathic surgery procedureswith bimaxillary osteotomy were divided into 2 groups:group A was treated with a piezosurgery device, and group B, witha reciprocating saw and bur.The piezosurgical bone osteotomy permitted individualized cutdesigns. The surgical time in group A was reduced, with a mean forthe mandibular osteotomy (1 side) between 3 minutes 31 seconds and5 minutes 2 seconds, whereas in group B, the surgical time wasbetween 7 minutes 23 seconds and 10 minutes 22 seconds. Thesurgical time in group A for the Le Fort I osteotomy was between5 minutes 17 seconds and 7 minutes 55 seconds in group A andbetween 8 minutes 38 seconds and 15 minutes 11 seconds in groupB. All patients in group A had a low blood loss (G300 mL) versuspatients of group B who had a medium to high blood loss (mediumloss: 400 mL, high loss: 9500 mL). Inferior alveolar nerve sensationwas retained in 98.2% of group A versus 92.7% in group B at6 months postoperative testing.Piezoelectric osteotomy reduced surgical time, blood loss, andinferior alveolar nerve injury in bimaxillary osteotomy. Absence ofmacrovibrations makes the instrument more manageable and easy touse and allows greater intraoperative control with higher safety incutting in difficult anatomical regions.
