目的探讨超声骨刀在下颌角肥大矫正术各部位骨质截除的临床应用方法、效果和价值.方法下颌角肥大美容就医者30例,其中男5例,女25例,均采用鼻插管全身麻醉,口内切口,骨膜下分离充分显露下颌骨,注意妥善保护颏神经,根据不同类型下颌角肥大的术前设计,用超声骨刀分别或同时进行下颌角截骨、下颌缘截骨、下颌骨外板劈除等操作.结果超声骨刀可以完全截断下颌角骨质,顺利完成下颌角整形截骨的各项操作,比传统的刀锯更加精确,截骨曲线流畅.所有受术者均未出现血管、神经意外损伤及骨折现象,术后随访1年,截骨线条美观,外形稳定,形态效果满意.结论采用超声骨刀进行下颌角肥大矫正术,可较好地提高手术精确度和安全性,但较传统刀具,超声骨刀截骨时间略长,必须熟悉与刀具不同的操作方式和手感.

Objective To explore the clinical method and effect of ultrasonic osteotomy in mandibular angle reduction.Methods Under intronasal approach and general anesthesia,30 patients (5 male patients and 25 female patients) underwent intraoral prominent mandibular angle reductions with ultrasonic osteotomy.The jaw bone under periosteum was explored and the mental nerves protected.According to the clinical features of mandibular angle,curved mandibular angle osteotomy,mandible margin osteotomy or outer cotex splitting osteotomy were performed.Results All the osteotomy of prominent mandibular angle reductions could be completed with ultrasonic osteotomy.There were no complications of bleeding,nerve injury and malfracture happened.After 1 year following-up,the outlines of lower mandible were natural and concordant.Compared with traditional osteotomy devices,ultrasonic osteotomy was smoother and more precisely.Conclusions Ultrasonic osteotomy can improve the precise and safty of mandibular angle reduction.but compared with traditional osteotomy devices,it takes more time for osteotomy procedure.Surgeons need adapt to the different feeling and control methods.
