目的：探索应用CT三维重建技术立体观察下斜肌形态的可行性。<br> 方法：临床诊断单眼先天性上斜肌麻痹的患者29例进行眼眶CT扫描。用Mimics软件对原始CT扫描数据进行三维重建，建立基于个体CT扫描数据的下斜肌数字图像，观察双眼下斜肌的3D形态。用自身对照设计，比较麻痹眼和健眼下斜肌最大横径差异，设定P<0.05为具有统计学意义。<br> 结果：先天性上斜肌麻痹患者麻痹眼的下斜肌有的比健眼下斜肌粗；有的比健眼下斜肌细。下斜肌最大横径的测量：麻痹眼下斜肌最大横径平均为6.797依1.083 mm；健眼下斜肌最大横径平均为6.507依0.848 mm；两者的差异不明显，无统计学意义(P>0.05)。<br> 结论：基于CT扫描数据的下斜肌三维重建数字图像可以用于观察下斜肌的形态。

AIM: To investigate the viability of the morphology of inferior oblique muscle observed stereoscopically using 3-dimensional CT reconstruction technique. <br> METHODS: This control study included of 29 cases which were clinically diagnosed with monocular congenital superior oblique palsy, examined by dimensional CT. The images of the inferior oblique muscle were reconstructed by Mimics software. 3D digital images on the basis of CT scanning data of the individuals were established. Observing the morphology of binocular inferior oblique muscle by self-controlled design, we compared the maximum transverse diameter of inferior oblique muscle of paralyzed eye with non-paralyzed one. We chose 5% as the significant level. <br> RESULTS: The reconstructed results of 3-dimensional CT scan showed that not all of the inferior oblique abdominal muscle of paralyzed eyes were thinner than that of the non-paralyzed eye in maximum transverse diameter of cross - sectional area. The maximum transverse diameter of inferior oblique muscle was measured. The average maximum transverse diameter of the paralyzed eye was 6. 797±1. 083mm and the non-paralyzed eye was 6. 507 ± 0. 848mm. The maximum transverse diameter of inferior oblique muscle of paralyzed eye did not, however, differ significantly from the normal (P>0. 05). <br> CONCLUSION: The three - dimensional CT reconstruction technology can be used for preoperative evaluation of the morphology of inferior oblique muscle.
