【摘要】目的:通过对颅底CT和颅底标本进行对照研究,观测国人卵圆孔的形态,测量其径值,为临床射频温控热凝术治疗三叉神经痛提供依据。方法:分别观测卵圆孔颅底CT图像205例(410侧)和78例颅骨标本(156侧)的卵圆孔形态和径值,进行两者对比分析。结果:卵圆孔颅底CT扫描其形态与颅底标本观测均可分为5种类型:卵圆形、圆形、肾形、梨形、长条形。± mm、± mm;± mm、± mm。颅底CT测量和颅底标本测量差异无统计学意义(P>);卵圆孔在性别上存在差异(P<)。在侧别上长径差异无统计学意义(P>),而宽径有统计学意义(P<)。结论:卵圆孔颅底CT能客观反映国人卵圆孔的形态和径值,可以为临床射频温控热凝术治疗三叉神经痛提供依据。

[Abstract] Objectve:CT images on base of skull ples, to observe and measure the shape and diameter of foramen ovale cranium and provide basis for treating trigeminal nenralgia perature-controlled thermocoagulation therapy. Methods: To analyze and pare the shape and diameter of foramina ovale on 205 adult CT images on base of skull(410 sides) ples(156 sides). Results: Both of the appearance of foramen ovale cranium on CT and the observation of basalis samples could be divided into five types: oval shape,round shape, pear shape,long shape and kidney average length of foramina ovale m on CT images and ± mm in basalis samples. And the average breadth m on CT and ± mm in basalis ages on base and samples(P>), but there ages on base of skull can reflect the shape and diameter of foramen of cranial base objectively and provide basis for treating trigeminal neuralgia
