摘　　要：目的:利用超声骨刀切开、钛板/钛网固定,采用正颌外科手段治疗12例伴错位愈合的上颌骨陈旧性骨折,评价其临床效果。方法:对12例上颌骨陈旧性骨折患者,采用Le Fort I型截骨术进行治疗。术中应用意大利Mectron的超声骨刀代替摇摆据进行切开,微型钛板/钛网固定,随访6～12个月,评价术后功能和美观效果。结果:利用超声骨刀切骨,切割高度精确,并且上颌骨没有发生任何振动损伤。手术所需时间比常规钻所用时间稍长。骨愈合良好,无任何神经血管异常。伤口一期愈合,咬合关系及外观满意或基本满意。结论:超声骨刀可用于颌骨陈旧性骨折的切开,精确度高,损伤小。PURPOSE： To evaluate the clinical applicability of Piezosurgery osteotomy： a new safe technique in managing long standing maxillary fractures. METHODS： 12 patients with long-standing maxillary fractures were surgically treated using Le Fort Ⅰ osteotomy. During operation, Piezosurgery osteotomy was used for bone cutting and splitting. After repositioning, the bone segments were rigidly fixed with micro Ti-plate, Ti-mesh. All the patients were followed up for 6 to 12 months, and the functionaland esthetic results were evaluated. RESULTS： Ultrasonic microvibrations allow accurate bone cutting without oscillating injuries to the soft tissue. All the wounds healed primarily without complications. The postoperative occlusion and appearance were satisfactory. CONCLUSIONS： Maximal recovery of mastication and appearance can be achieved by using Piezosurgery osteotomy with fixation materials such as Ti-plates and Ti-meshes in selected patients with long-standing maxillary fractures.
