摘要
骨切割是临床医学的一项基本技术，涉及与骨组织手术有关的临床学科，如口腔科、骨科、整形外科、神经外科和耳鼻咽喉科等。骨切割的效率和质量，直接影响到疾病的治疗效果。因此，临床上一直在探寻安全、高效的骨切割技术。骨切割技术的发展经历了传统的手动、气动和电动等切割方式，目前出现的超声骨切割技术将其带人了一个全新的时代。
Ultrasonic osteotomy is a new technique for osseous surgery utilizing an innovative ultrasonic surgical apparatus. Oral surgeons have started using this newly developed ultrasonic bone scalpel when performing precise osteotomies. This technique is known as piezosurgery also and has found wide applications in dental and medical specialities. Numerous protocols including conventional diamond round bur, safe scraper, rongeur pliers and gouge shaped bone chisel have been proposed to simplify osteotomy and osteoplasty in bone surgery before this technique was created. But only ultrasonic osteotomy could reach high levels of precision and safety as compared to those instruments. Ultrasonic osteotomy device is characterized by piezoelectric ultrasonic vibrations of a frequency of 25-29 kHz and a range between 60-200μm. Due to low-frequency ultrasonic vibration, the device precisely cuts bone without cutting soft tissue even in case of accidental contact. It also maintains a blood-free site during cutting bone. This technique was first used in sinus floor elevation for bony window osteotomy and sinus membrane elevation. After several years, this technique is utilized in more and more dental indications such as ridge expansion, maxillary sinus floor elevation, harvesting of bone graft, extraction and socket debridement for the installation of immediate-loaded implants, extraction of third molars, periodontal surgery, cyst exeresis and inferior alveolar nerve transposition. It＇s also reported in hand surgery, cranial osteoplasty and segmental maxillary Le Fort osteotomy. Ultrasonic osteotomy is different from the conventional techniques utilized and proved to be a safe and useful technique in bone surgery.
