汉族人下颌角相关的三维CT与大体测量的比较研究

目的 通过对汉族成年男女颅颌面软组织及螺旋CT三维重建骨性数据测量，并与颅骨测量数据对比分析，研究对颌面部诊断、治疗的影响因素。同时，也为下一步诊断模型的建立、调试奠定基础。方法 随机选取汉族成年男女各20例（无颅骨明显畸形），进行颅颌面软组织测量及螺旋CT三维骨性测量，并行统计学分析。结果 颌面部软组织对汉族男女性别特征的判断影响很大。在大体测量中，男女的头长、头宽、面中宽及表示下面部特征等多个数据的差异明显，三维CT与颅骨骨性测量的结果基本一致。结论 三维螺旋CT与颅骨测量有良好的一致性；颌面部软组织对汉族人的性别判断、颌面诊疗影响很大。在治疗下面部畸形过程中，不仅需要对骨性的处理，还需要对软组织进行处理。这一点对女性患者尤为重要。

Comparative research of three-dimensional CT and general measure related to mandible of Han nationality people

Objective By measuring the parenchyma of skull and jaw of adult men and women of han nationality and spiral three - dimensional CT rebuilt bone, and comparing with the measuring data of the skull, we investigated influencing factors related with the diagnosis and treatment to the jaw, and established a foundation for the adjustment of the diagnosis model simulaneous. Methods Twenty cases of both adult men and adult women of Hart nationality without skull abnormality were chosen randomly. The parenchyma of skull and jaw was general measured and the bone was also done by the spiral 3D- CT. And then the statistic analysis to the data was carried out. Results Jaw and facial parenchyma has a great influence to gender judgment of men and women. The measure result of han nationdity adult people of the length of head, the midth of middle face and othen date which realted to the lower face are different significanty. There is correspondence basically between spiral three - dimensional CT and oaseoue measure of the skull bone. Conclusion There is correspondence basically between spiral three - dimensional CT and osseoue measure of the skull bone. Jaw and facial parenchyma has a great influence to gender judgment of Hart nationality people, and also the diagnosis and treatment of the jaw and face. In the treatment of the lower facial abnormality, not only the osteal treatment but also the adjustment of the parenchyma is necessary.
