The purpose of this study was to evaluate specific parameters: intra-operative time, facial swelling, degree of pain (VAS scale), recovery time and neurosensory disturbance in patients who underwent orthognathic surgery either using piezo or saw devices.
We designed a retrospective study, which included 100 patients who underwent bilateral sagittal split osteotomy (BSSO) surgery combined with maxillary Le Fort I. They were separated into 2 groups of 50 patients each. The surgeries were performed between September 2015 and April 2017 by the same surgeon.
Intra-op time is unchanged but patients operated with the Piezo devices requested fewer painkilling medication and were dismissed on the second day after the surgery. Neurosensory recovery was statistically significant in the Piezo group.
Far less post-op swelling and the reduction in the use of painkillers lead to a speedier recovery in patients who underwent orthognathic surgery using Piezosurgery. These patients also recovered more sensitivity in the lower lip area.

本研究旨在评估以下特定参数：术中时间、面部肿胀、疼痛程度（VAS 量表）、恢复时间和感觉神经障碍，这些参数在使用超声骨刀或锯设备进行正颌手术的患者中存在差异。
我们设计了一项回顾性研究，共纳入 100 例接受双侧矢状劈开截骨术（BSSO）联合上颌 Le Fort I 截骨术的患者，将其分为两组，每组 50 例。这些手术均由同一位外科医生于 2015 年 9 月至 2017 年 4 月期间进行。
手术过程中时间保持不变，但使用超声骨刀的患者需要的止痛药物更少，并且可以在手术后第二天出院。超声骨刀组的神经感觉恢复有显著差异。
使用超声骨刀进行正颌手术的患者术后肿胀程度明显减轻，止痛药使用量减少，恢复更快。这些患者的下唇区域的敏感性也得到了更快的恢复。
