Ultrasonic bone-cutting surgery has been recently introduced as a feasible alternative to the conventional tools of cranio-maxillo-facial surgery, due to its technical characteristics of precision and safety. The device used is unique in that the cutting action occurs when the tool is employed on mineralized tissues, but stops on soft tissues. This technical note illustrates the use of Piezosurgery for all osteotomies of surgically assisted rapid maxillary expansion (SARME). The procedure, including pterygo-maxillary detachment, can be completed under local anaesthesia. Other advantages include minimal risk of jeopardizing critical anatomic structures (e.g. palatine artery), minimal intraoperative bleeding and postoperative swelling, and minimal thermal damage to bone surfaces. Narrow and rectilinear osteotomies can be easily performed with varying vibrating scalpels, at the cost of a longer operative time.
由于其精准和安全的技术特性，超声骨切割手术最近已被引入，作为颅颌面外科传统工具的一种可行替代方案。所使用的设备独特之处在于，当工具应用于矿化组织时会发生切割动作，但在软组织上则停止。本技术说明阐述了压电手术在手术辅助快速上颌扩弓（SARME）所有截骨术中的应用。该手术，包括翼上颌分离，可以在局部麻醉下完成。其他优点包括危及关键解剖结构（如腭动脉）的风险最小、术中出血和术后肿胀最小，以及对骨表面的热损伤最小。使用不同的振动手术刀可以轻松进行狭窄和直线形截骨术，代价是手术时间较长。
