目的 研究128层螺旋CT曲面重建 在颌骨骨折和牙齿与颌骨关系中的诊断价 值。方法 选择从2013年5月至2015年5月 我院收治的88例颌骨骨折患者作为研究对 象，对这批患者分别进行常规CT扫描和 128层CT扫描，将扫描结果与最终手术结 果对比，比较这两种方法对颌骨骨折的诊 断准确率，以及牙齿与颌骨关系的诊断结 果。结果 128层螺旋CT曲面重建在颌骨骨 折诊断的准确率为96.59%，显著高于常规 CT扫描的87.50%，差异存在统计学意义(P ＜0.05)。结论 128层螺旋CT扫描以及数 据曲面重建对于颌骨骨折的诊断准确率 高，能良好反映牙齿和颌骨之间的关系， 值得临床推荐。

Objective To study the value of 128-slice spiral CT reconstruction in jaw fracture and the analysis of relationship between teeth and jaw. Methods Eightyeight cases of jaw fracture examined by the routine CT scan and 128-slice spiral CT scan from May 2013 to May 2015 in our hospital were chosen as object of study. We compared the surgical results with scan results, and compared the diagnostic accuracy of the two methods in oral maxillofacial fractures as well as the relationship between teeth and jaws. Results The accuracy of 128-slice spiral CT scanning for jaw fracture was 96.59%, significantly higher than that of conventional CT scanning, it is statistically significant(P<0.05). Conclusion 128-slice spiral CT curve-plane reconstruction has a high accuracy in diagnosis of jaw fracture, can effectively render the relationship between the teeth and jaws, and is worthy of clinical practice.
