摘要:: 目的　探索ＣＴ三维重建技术在先天性上斜肌麻痹形态检测中的应用。方法　我们对２７例临床诊断为单眼先天性上斜肌麻痹的患者进行了眼眶ＣＴ扫描。用ＭＩＭＩＣＳ１０．０１软件对原始ＣＴ扫描数据进行三维重建，建立基于个体ＣＴ扫描数据的上斜肌虚拟模型，以此观察双眼上斜肌的形态。采用自身对照，比较麻痹眼和健眼的上斜肌体积差异，设定Ｐ＜０．０１为差异有显著性意义。结果　２７例患者的上斜肌三维重建模型都显示，麻痹眼的上斜肌与健眼的上斜肌相比肌肉明显纤细。上斜肌体积的测量：麻痹眼上斜肌肌腹体积为（２６．４５±１０．７８）ｍｍ３，健眼上斜肌肌腹体积为（６０．５１±１７．７６）ｍｍ３，两者间的差异有统计学意义（Ｐ＜０．０１）。结论　基于ＣＴ扫描数据的上斜肌三维重建技术可以用于观察上斜肌的形态。

Abstract:: Objective To study the application of three-dimensional CT reconstruction technology in morphologic observation of congenital superior oblique palsy. Methods This self control study included 27 cases diagnosed with monocular congenital superior oblique palsy for 3-dimensional CT. The images of the superior oblique were reconstructed by Mimics 10. 01 software. The volume of superior oblique muscle of paralyzed eye with non-paralyzed one was compared. P < 0. 01 was chosen as the significant level. Results The reconstructed results of 3-dimensional CT scan in 27 cases showed that the volume of the oblique abdominal muscle cross-sectional area of the paralyzed eye was sigruficantly lower than that of the non-paralyzed eye. The volume of the paralyzed eye was ( 26. 45 + 10. 78) mm3 and the non-paralyzed eye was ( 60. 51 +17. 76) mm3 . there was statistical difference (P < 0. 01 ) . Coriclrisiori The three-dimensional CT reconstruction technique can be used for preoperative evaluation of superior oblique muscle morphology.
