This study was designed to evaluate the usefulness of the Sonopet UST-2001 (Miwatec Co., Ltd., Kawasaki, Kanagawa, Japan) ultrasonic curettage device, and to assess the outcome after intraoral vertical ramus osteotomy (IVRO). Thirteen Japanese adults (age range 20-41 years, mean age 29.6 years) presented with jaw deformities diagnosed as mandibular prognathism and asymmetry; they all underwent IVRO of the mandible. This procedure was followed by ultrasonic bone curettage using the Sonopet to make a guiding notch or groove in the lateral cortex of the ramus without damaging the vessels and nerves. After surgery, the osteotomy line was evaluated by three-dimensional computed tomography. In all patients, osteotomy with the Sonopet device was achieved safely, with minimal bleeding and no major complications. The distal segment could be moved into its ideal position and all patients achieved their ideal profiles. Ultrasonic bone curettage is a safe method for making a guiding groove, without damage to surrounding tissue, prior to complete IVRO.
本研究旨在评估Sonopet UST - 2001（日本神奈川县川崎市Miwatec有限公司）超声刮治设备的实用性，并评估口内垂直升支截骨术（IVRO）后的效果。13名日本成年人（年龄范围20 - 41岁，平均年龄29.6岁）因诊断为下颌前突和不对称的颌骨畸形而就诊；他们均接受了下颌骨的IVRO手术。该手术之后，使用Sonopet进行超声骨刮治，以便在升支外侧皮质上制作引导切口或凹槽，同时不损伤血管和神经。术后，通过三维计算机断层扫描评估截骨线。在所有患者中，使用Sonopet设备进行截骨术均安全完成，出血极少且无重大并发症。远端骨段能够移动到理想位置，所有患者均获得了理想的外形。在完全进行IVRO之前，超声骨刮治是一种制作引导凹槽的安全方法，不会对周围组织造成损伤。
