目的:总结压电超声骨刀在颌骨囊肿摘除术中的临床应用特点,并评价其临床效果。方法:对41例颌骨囊肿病例,应用压电超声骨刀进行骨开窗,其中8例配合使用电钻,摘除囊肿,6例囊腔用钛板将游离的自体骨块复位固定,关闭骨腔。观察超声骨刀的临床使用特点及临床效果。结果:41例均完整摘除颌骨囊肿,其中1例因术中操作不当致鼻底黏膜损伤,其余病例无软组织损伤。伤口一期愈合。8例配合使用电钻者,骨切割效率明显提高。结论:颌骨囊肿摘除术中应用压电超声骨刀,手术精确度高,安全,方便。
OBJECTIVE: To summarize the clinical features of piezoelectric ultrasonic osteotome in the removal of jaw cyst and to evaluate its clinical effect. Methods: Forty-one cases of jaw cysts were treated by piezoelectric ultrasonic osteotome for bone fenestration, 8 cases were operated with electric drill, cysts were removed, 6 cases were treated with titanium plates to restore and fix the free autologous bone, . To observe the clinical features and clinical effects of ultrasonic osteotome. Results: All the 41 cases had complete removal of the jaw cysts, of which 1 case had nasal mucosal injury due to improper intraoperative management, and the remaining cases had no soft tissue injury. A wound healing. 8 cases with the use of electric drill who significantly improved bone cutting efficiency. Conclusion: The application of piezoelectric ultrasonic osteotome in the removal of jaw cyst has the advantages of high precision, safety and convenience.
