摘要
目的:探讨颞下颌关节(temporom and ibu lar joint,TM J)形态的多排螺旋CT(mu ltislice helical computed tomo-graphy,MSCT)影像测量与解剖测量的相关关系。方法:MSCT对4具成人和4具儿童尸体TM J扫描,经多层面后重建处理,对反映TM J形态的参数进行测量,并在标本上进行相应部位相应参数测量,两者测量结果进行相关性分析。结果:有关TM J骨性部分的参数两种测量结果间有非常显著的正相关关系,关节盘厚度的测量,两种方法间有较大的正相关关系。结论:可以利用MSCT对TM J形态进行定性和定量研究。
Objective： To study the relationship of the measurements with multislice helical computed tomography （MSCT） multiplanar reformations （MPR） images and anatomic measurements of the temporomandibular joint （TMJ） morphology. Methods： 16 TMJs of 4 adults and 4 children cadavers underwent MSCT. Parameters that could reflect TMJ morphology were taken in the MPR images and cadavers dissection. The relationship of two measurements was analysed. Resuits： Significant correlation was found between two measurements in the length （ r = 0. 9996, P 〈 0.01 ） , angle （ r = 0. 9980, P 〈0.01 ） and area（ r =0. 9974, P 〈0.01 ） of TMJ osseous tissue. Also correlation （ r = 0. 9481, P 〈 0.01 ） was found in the thickness of the discs. Conclusion： MSCT may be a reliable means for the qualitative or quantitative analysis of anatomical morphology of TMJ, particular for TMJ osseous tissue.
