Results The changes of extraocular muscles were not only the adhension with surrounding and incarceration with the fracture, but also the aspects themselves, appearance, location, thickness, macroaxis turning, and so on; Incarceration and herniation were few in medial orbital wall fracture ,but often in orbital floor fracture; Incarceration and herniation were more frequently in children than in adults; Coronal scanning, horizontal scanning and anteroposterior axes reconstitution had the different value.

结果 眼外肌除与周围有粘连和嵌顿外，还可见自身有形状、厚度、位置、长轴旋转等改变；内壁骨折极少引起内直肌嵌顿，下壁骨折中下直肌嵌夹及疝出则常见；未成年人下直肌嵌夹及疝出较成人常见；CT横轴位和冠状位，以及矢状重建在观察软组织变化中价值不同。
