Summary
Piezosurgery in orthognathic surgery leads to reduced pain, less swelling, and faster recovery compared to traditional saw devices. Patients experienced quicker neurosensory recovery and improved sensitivity post-operation.
Area of Science:
- Oral and Maxillofacial Surgery
- Surgical Technology
Background:
- Orthognathic surgery corrects jaw misalignments.
- Comparing piezoelectric devices (Piezosurgery) with traditional saw devices is crucial for optimizing patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of Piezosurgery versus saw devices in orthognathic surgery.
- Key parameters assessed include operative time, facial swelling, pain, recovery duration, and neurosensory disturbance.
Main Methods:
- Retrospective study of 100 patients undergoing bilateral sagittal split osteotomy (BSSO) and Le Fort I maxillary osteotomy.
- Patients were divided into two groups (50 each) based on the surgical device used: Piezo or saw.
- Surgeries were performed by the same surgeon between September 2015 and April 2017.
Main Results:
- Intra-operative time remained consistent between groups.
- Patients undergoing Piezosurgery required less pain medication and were discharged earlier (post-operative day 2).
- Statistically significant improvements in neurosensory recovery were observed in the Piezosurgery group.
Conclusions:
- Piezosurgery significantly reduces post-operative swelling and painkiller requirements, leading to a faster recovery after orthognathic surgery.
- Patients treated with Piezosurgery demonstrated enhanced recovery of lower lip sensitivity.
