    Summary
    This summary is machine-generated.

    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.
