Abstract

Aim: This study aimed to compare piezosurgery and conventional saw osteotomy ‎and evaluate the impact of the two surgical tools on operation time, intraoperative ‎bleeding, postoperative edema & Coagulative bone necrosis in genioplasty.‎
Materials and Methods: Ten patients undergoing genioplasty were divided into two ‎groups. In Group A (n=5), piezosurgery was used for osteotomy on the right side, and a ‎conventional saw on the left. In Group B (n=5), the osteotomy tools were reversed. All ‎parameters were assessed and compared between the two techniques.‎
Results: The operation time was longer with piezosurgery compared to the ‎conventional saw. Regarding blood loss and Coagulative bone necrosis the Saw group ‎demonstrated higher than piezosurgery. However, there was no significant difference in ‎the amount of postoperative edema between the two techniques
Conclusion: While piezoelectric surgery offers advantages in bone healing, reduced ‎blood loss, and decreased bone necrosis in mandibular orthognathic procedures, it is ‎associated with longer operative times and does not significantly reduce postoperative ‎edema compared to conventional saw techniques.‎
