目的：探讨螺旋CT三维重建技术在下颌骨畸形整形中的应用价值。方法：自2012年3月-2013年3月我院收治的下颌骨畸形患者18例，对其术前术后进行螺旋CT断层扫描和三维重建，垂直测量咬合平下颌面部位第一磨牙、第二前磨牙、第二磨牙至下颌骨下缘的距离和下颌骨升支中部至下颌角的距离，并正常侧分别与术前畸形侧、术后畸形侧上述距离的比较。结果：正常侧和术前畸形侧的第一磨牙、第二前磨牙、第二磨牙至下颌骨下缘的垂直距离和下颌骨升支高度进行对比，差异显著，有统计学意义（P<0.05）。正常侧与术后畸形侧比较上述距离差异无统计学意义。结论：下颌骨畸形整形中运用螺旋CT三维重建技术，可以准确判断手术部位，精确测量截骨量，保证手术安全、顺利进行，具有极大的应用价值。
目的：探討螺鏇CT三維重建技術在下頜骨畸形整形中的應用價值。方法：自2012年3月-2013年3月我院收治的下頜骨畸形患者18例，對其術前術後進行螺鏇CT斷層掃描和三維重建，垂直測量咬閤平下頜麵部位第一磨牙、第二前磨牙、第二磨牙至下頜骨下緣的距離和下頜骨升支中部至下頜角的距離，併正常側分彆與術前畸形側、術後畸形側上述距離的比較。結果：正常側和術前畸形側的第一磨牙、第二前磨牙、第二磨牙至下頜骨下緣的垂直距離和下頜骨升支高度進行對比，差異顯著，有統計學意義（P<0.05）。正常側與術後畸形側比較上述距離差異無統計學意義。結論：下頜骨畸形整形中運用螺鏇CT三維重建技術，可以準確判斷手術部位，精確測量截骨量，保證手術安全、順利進行，具有極大的應用價值。

Objective:To study the application value of spiral CT three-dimensional reconstruction technology in plastic mandibular malformation. Method:From March,2012 to March,2013,18 cases of mandibular malformation patients admitted in March,the spiral CT scanning and three-dimensional reconstruction, vertical measurement was done on maxillofacial first molars,the second premolars,the distance to the edge of mandibular second molars and the distance of mandibular central branch to mandibular angle,and the distance among the normal,malformation before operation and malformation after operation were compared. Result:Maxillofacial first molars,the second premolars,the distance to the edge of mandibular second molars and the distance of mandibular central branch to mandibular angle of the normal side and malformation before operation was compared,with significant difference and with statistical significance(P<0.05). There was no statistical meaning between normal side and malformation side after operation. Conclusion:Mandibular deformities in the plastic using spiral CT 3 d reconstruction technology can accurately judge the surgical site,accurate measurement osteotomy,to assure the safety of surgery and smoothly,and it has great application value.
