笔者分析４０例儿童眼眶骨折。受伤原因以撞伤、摔伤多见，拳击伤少见。主要表现为视力下降甚至失明、复视及眼球运动障碍。ＣＴ检查常规为水平位及冠状位扫描。主要ＣＴ表现为眶壁骨质连续性中断，占７１．４％，眶壁移位眶腔扩大占２８．６％；眶壁直接骨折最多达５０．５％，爆裂骨折占３３．３％，复合骨折占１６．７％；各壁骨折发生率依次为内壁、下壁、外壁及上壁；此外骨折局部可伴有软组织增厚及眼外肌改变。初步认为儿童眼眶骨折具有一定特征，ＣＴ检查利于早期诊断，对选择治疗方法及估测预后有指导意义。同时笔者还对ＣＴ表现的机理、意义、与成人眶壁骨折的区别进行了分析。
The author analyzes 40 cases of orbital fracture in children. Injuries to bruises, fall more common, boxing injury rare. Mainly manifested as decreased vision or blindness, diplopia and eye movement disorders. CT examination for horizontal and coronal scanning routine. The main CT showed interrupted orbital bone continuity, accounting for 71.4%, orbital displacement orbital enlargement accounted for 28.6%; orbital wall fracture up to 50.5%, burst fracture accounted for 33.3% Composite fractures accounted for 16.7%; the incidence of fractures of each wall were the inner wall, the lower wall, the outer wall and the upper wall; in addition fracture may be associated with soft tissue thickening and extraocular muscle changes. Preliminary thought that children with orbital fractures have certain characteristics, CT examination is conducive to early diagnosis, the choice of treatment methods and prognostic guidance. At the same time I also on the CT performance of the mechanism, significance, and the difference between adult and orbital fracture were analyzed.
