摘　　要：目的：研究计算机辅助三维手术模拟系统在髁突骨软骨瘤切除后下颌升支后缘上移髁突重建术中的作用，并探讨其临床应用价值。方法：2007～2009年期问，6例髁突骨软骨瘤患者，利用SurgicaseCMF软件行术前设计和三维手术模拟得出相关数据，辅助行病变髁突切除术和升支后缘切开上移髁突重建术。术后行临床检查、放射检查对骨瓣愈合情况和颞下颌关节功能进行评价。结果：所有的患者均获得良好的开口度，未见下唇麻木病例。全景片显示下颌升支后缘的上头位于关节窝内，无骨粘连和骨吸收。结论：在骨软骨瘤患者下颌升支后缘上移髁突重建手术中，应用计算机辅助三维手术模拟系统可以使得手术更加精确和方便，避免了对重要结构的损害，提高了患者的满意度。Objective： This paper presents the application of computer-assisted 3-D surgical planning in condylar reconstruction by osteotomying ramus for patients with osteochondroma. Methods： Six patients with osteochondroma of the mandibular condyle fi＇om 2007 to 2009 received computer-assisted 3-D surgical planning and simulation using Surgicase CMF software before surgical treatment including condylectomy and condylar reconstruction by vertical sliding osteotomy of the mandibular ramus. Clinical examination, radiographs, and photographs were used postoperatively to evaluate the grafts and TMJ function. Results： Satisfactory mouth opening was achieved in all cases. Panoramic radiograph showed that the upper head of the posterior ramus border existed in the glenoid fossa. Nonunion,postoperative numbness of the lower lip and bone resorption were not observed. Conclusion： Combined application of computerassisted 3-D surgical planning and simulation with vertical ramus osteotomy for reconstruction of condyle for patients with osteochondroma makes the surgery more accurate and more convenient, avoids damage of vital structures and improves patient satisfaction.
