ABSTRACT
Mandibular osteotomy carries with it a risk of damaging blood vessels and nerves when using traditional surgical techniques. Piezosurgery®, is a new technique that uses ultrasonic vibration to enable bone-selective sectioning without damage to the surrounding soft tissues. However, paralysis may not be completely eliminated using Piezosurgery® for osteotomy. We investigated how piezoelectric surgery in bilateral sagittal splitting ramus osteotomy (BSSRO) affected the surrounding soft tissue. Forty-four patients with skeletal mandibular prognathism underwent mandibular setback with BSSRO. Patients were divided into two groups, those treated by the conventional chisel technique and those treated by Piezosurgery®. Osteotomy time, blood loss, and incidence of paresthesia were compared retrospectively. Osteotomy time and blood loss in the piezo group were significantly reduced compared to the chisel group. Interestingly, whereas paresthesia incidence immediately after the operation did not differ between the groups, paresthesia in the piezo group 3 months postoperatively was significantly less than in the chisel group. However, a few cases of paralysis did not recover even in the piezo group. Blood loss and osteotomy time did not correlate with the paralysis. This study demonstrates that while piezoelectric surgery does impact the nerve tissue, the use of piezoelectric surgery in BSSRO leads to significantly less long term paralysis compared to surgery done by chisel.
