摘　　要：目的 探讨MSCT测量圆孔骨性通道相关参数的数值范围.方法 回顾性分析2014年1月1日-2014年8月20日在南通市第一人民医院行头颅、鼻窦和眼眶MSCT检查的152例非外伤性患者的临床资料.其中男80例,年龄16~89岁;女72例,年龄17~79岁.所有患者行MSCT扫描,从冠状面、横断面、矢状面上显示152例304侧圆孔骨性通道,在MSCT图像上测量圆孔的深径D、圆孔中轴线与翼腭窝中轴线的夹角B、两侧圆孔中点连线与圆孔中轴线的夹角A1、同侧圆孔中轴线与翼腭窝中轴线的夹角A2、同侧圆孔外口外侧和内口内侧连线与翼腭窝中轴线的夹角A3.对比相同性别不同侧别间及同一侧别不同性别间圆孔骨性通道的相关参数,计算测量数据的变异系数（CV） 和测量者个体间的CV,并采用组间相关系数（ICC）分析各测量参数的可信度.结果 MSCT能够清晰显示152例304侧圆孔的形态、大小及走行,图像质量良好.圆孔深径D值为（4.76±1.61） mm,角B、A1、A2、A3分别为93.13°±8.68°、87.78°±8.64°、134.49°±8.63°、160.16°±8.22°.相同性别不同侧别间比较：角A1右侧均大于左侧,差异均有统计学意义（P值均〈0.05）;而圆孔深径D和角B、A2、A3右侧和左侧间差异均无统计学意义（P值均〉0.05）.同一侧别不同性别间比较：圆孔深径D和角A1、A2、A3 、B在男性、女性间差异均无统计学意义（P值均〉0.05）.D、 B、 A1、A2、A3的CV范围分别为31.58%~37.14%、8.15%~9.78%、8.35%~9.94%、5.50%~6.74%、4.43%~5.59%;测量者间的CV分别为20.63%~21.54%、9.13%~9.16%、2.54%~3.77%、2.00%~2.59%、1.58%~2.69%.角B测量可信度为较好,圆孔深径D和角A1、A2、A3的测量可信度为极佳.结论 在MSCT图像上对圆孔骨性通道进行测量,其结果稳定、可靠,可以为临床应用提供参考依据.Objective To investigate the parameter ranges of the bone passage of foramen rotundum on MSCT images.Methods Clinical records of 152 non-traumatic patients （80 males aged 16-89 years and 72 females aged 17-79 years）, who underwent MSCT of skulls, paranasal sinuses and eyepits from January 1, 2014 to August 20, 2014, were reviewed retrospectively.On the coronal, cross-sectional and sagittal plane images of 304 sides of the foramen rotundum, the following parameters were measured： longitudinal diameter of foramen rotundum （D）, angle between the central axes of foramen rotundum and pterygopalatine fossa （B）, angle between the connection of the midpoints of both sides of foramen rotundum and its central axis （A1）, angle between the central axes of foramen rotundum and pterygopalatine fossa on the same side （A2）, angle between the central axis of the pterygopalatine fossa and the connection of internal and external port of foramen rotundum on the same side （A3）.Cross-side comparisons were made for the same gender and cross-gender comparisons were made on the same side.The coefficient of variation （CV） and the within subject CV were calculated.Reliability of the parameters measured were analyzed using correlation coefficient （ICC）.Results The shape, size and direction of the foramen rotundum could be clearly seen on MSCT with images of good quality.D was （4.76±1.61） mm, and B, A1, A2, A3 were 93.13°±8.68°, 87.78°±8.64°, 134.49°±8.63°, and 160.16°±8.22°.Cross-side comparisons were made for the same gender： A1 on the right side was greater than on the left with statistically significant differences （all P values〈0.05）, and D, B, A2, A3 had no significant differences between the two sides （all P values〉0.05）.cross-gender comparisons were made on the same side： D, A1, A2, A3 and B had no significant difference between males and females （all P values〉0.05）.The CV ranges of D, B, A1, A2, A3 were 31.58%-37.14%, 8.15%-9.78%, 8.35%-9.94%, 5.50%-6.74%, 4.43
