摘　　要：眼球运动障碍是眶壁骨折的常见临床症状。本文分析眼球运动障碍的175例眶壁骨折的CT资料。结果显示眼球垂直方向运动障碍最多103例,由眶上壁或/和眶下壁骨折引起,其中下壁占95.15%,多为中后段骨折,眶内组织脱出严重。水平方向运动障碍35例,由眶内壁或/和眶外壁骨折引起,其中内壁占77.14%,但眶内组织脱出相对较轻,骨折范围大。混合方向运动障碍30例,主要见于内、下壁同时骨折。眼球固定7例,见于眶尖综合征,多伴颅脑外伤。对上述结果进行了分析讨论。Oculomotor disturbance is a frequent clinical symptom of orbital fracture. CT findings of 175 cases with oculomotor disturbance involved in biotalr fracture were analyzed. The results showed as follows: Oculomotor disturbance in vertical direction resulting from superior or/and inferior orbital wall fracture occurred in 103 eases of which 95.15% had fracture of the inferior orbital wall and mostly occurred at the posterior segment of the wall with serious protrusion of the orbital tissue. Horizontal oculomotor disturbance occurred in 35 cases of which 77.14% resulted from medial orbital wall fracture and the rest from lateral wall fracture. Although the extent of fracture was larger in medial orbital wall, the orbital tissue protrusion was milder in degree. 30 cases with mixed oculomotor disturbance in multiple directions mostly had fractures at the medial and inferior walls. 7 cases with orbital apex syndrome and global fixation were often accompanied by craniocerebral trauma. The above results were analyzed and discussed.
