After the clinical introduction of ultrasound scalpel in recent years, piezosurgery has become competitive with conventional instruments in orthognathic procedures to reduce the operative and postoperative complications reported to occur in association with these surgeries.
The aim of this prospective clinical study was to compare intraoperative and postoperative outcomes of both piezoelectric device and the traditional bur technique in orthognathic surgery. Intraoperative bleeding time, operative time, postoperative swelling, and neurological impairment were evaluated.
In this study, a split-mouth technique was applied on ten patients requiring orthognathic surgery. To make the osteotomy cuts, on the one side, piezo-osteotome was used, and on the other side, conventional osteotomy bur was used.
Duration of osteotomy was found to be greater with piezo osteotomy compared to bur osteotomy. Mild bleeding was observed with piezosurgery. Postoperative swelling was greater on the side of piezosurgery compared to the bur side. Altered neurosensory activity was found to be equal on the 1 day postoperatively, but the piezo side recovered faster compared to the bur side in the 1 month after surgery.
Piezoelectric device offers better advantages over the conventional bur in orthognathic surgery and hence can be considered an alternative to the bur in some orthognathic procedures.
近年来超声刀临床应用后，压电手术在正颌手术中已能与传统器械竞争，以减少报道的与这些手术相关的手术中和术后并发症。
这项前瞻性临床研究的目的是比较压电装置和传统牙钻技术在正颌手术中的术中和术后结果。评估术中出血时间、手术时间、术后肿胀和神经损伤情况。
在本研究中，对10例需要正颌手术的患者采用了双侧对照技术。为进行截骨，一侧使用压电骨凿，另一侧使用传统截骨牙钻。
与牙钻截骨相比，压电截骨的截骨时间更长。压电手术观察到轻度出血。与牙钻侧相比，压电手术侧的术后肿胀更严重。术后第1天发现神经感觉活动改变程度相同，但术后1个月压电侧比牙钻侧恢复得更快。
在正颌手术中，压电装置比传统牙钻具有更好的优势，因此在某些正颌手术中可被视为牙钻的替代品。
