Purpose: This study evaluated outcomes of surgical treatment for enophthalmos after pediatric orbital blowout fracture. Associations of fracture type, fracture site, time from injury to treatment, and type of surgical procedure with treatment outcomes were assessed.

Methods: The medical records of 200 children and adolescents (38 girls and 162 boys) with orbital fractures treated in the authors’ department from 1975 to 2015 were reviewed retrospectively. The main causes of injury were accidental blows to the orbit and sports injuries. This study included only patients with fracture of the floor and/or medial wall of the orbit, which is referred to in the English literature as pure, or internal, blowout fracture. Patients with fracture of the orbital rim, lateral wall, or roof were excluded. Surgical treatment was performed for 178 patients; the other 22 children were treated conservatively.

Results: In the surgically treated group, treatment outcomes did not differ in relation to the severity of post-traumatic enophthalmos. The setting of the eyeball improved in 83% of patients.

Conclusion: The severity of post-traumatic enophthalmos was not associated with surgical outcome in children.

目的：本研究评估了小儿眼眶爆裂性骨折后的眼睑手术治疗的效果。评估骨折类型，骨折部位，从受伤到治疗的时间以及外科手术类型与治疗结果之间的关系。

方法：回顾性分析1975年至2015年作者部门治疗的200例眼眶骨折的儿童和青少年（38例女孩和162例男孩）的病历。造成伤害的主要原因是意外撞击轨道和运动伤害。该研究仅包括眶底和/或眼眶内壁骨折的患者，在英语文献中将其称为单纯或内部爆裂性骨折。眼眶缘，侧壁或房顶骨折的患者被排除在外。178例患者接受了外科手术治疗。其余22名儿童接受了保守治疗。

结果：在手术治疗组中，治疗结果与创伤后性眼睑的严重程度没有差异。83％的患者的眼球位置得到改善。

结论：小儿创伤后眼睑的严重程度与手术结局无关。
