Comparative evaluation of conventional and Piezoelectric Surgery in Sagittal Split Ramus Osteotomy- an in-vivo study
2021
Abstract-
Aim & Objective- Our aim was to compare the outcomes of piezoelectric surgery and conventional bur after Bilateral sagittal split osteotomy (BSSO). Piezoelectric surgical device is precise and safe than traditional bur in orthognathic surgery.
Materials &Method- Fourteen consecutive patients who underwent BSSO procedures were involved in the study. In seven patients procedure was performed using traditionalbur, the remaining seven patient’s osteotomies by a piezoelectric device. Intraoperative blood loss, procedure duration time, and nerve impairment were evaluated to compare the outcomes of these two procedures at 1 day, 1 week, 1 month, 3months & 6months.
Result- Compare to traditional mechanical surgery. Piezo-osteotomy showed a statistically significant reduction in postoperative nerve impairment.
Conclusion- The null hypothesis was rejected and our stated hypothesis proved strong, the use of piezoelectric of osteotomy found better than traditional bur. We believe that a piezoelectric device allows surgeons to achieve better results over traditional bur in terms of nerve impairment. This device represents a more precise and safer method to perform invasive surgical procedures such as BSSO
However, use of traditional but showed fast osteotomy eventually reducing procedural duration time but on the other hand in the deeper incision and vascular areas, use of bur found to be more aggressive as compared to piezoelectric device.
