目的：通过对眼眶内壁联合下壁骨折患者手术后眼球内陷治疗情况的临床观察，探讨不同手术位点的修复对手术预后的意义。

方法：回顾性分析眼眶内壁与下壁骨折伴眼球内陷23例23眼患者的临床资料。术后观察3mo，眼球内陷均小于2mm。通过术后CT检查，分析后隅角、内壁上缘、下壁外缘三个手术位点的修复情况。

结果：术后患者预后良好，三个手术位点的修复情况是不同的，其中后隅角的修复率最高(100%)，内壁上缘的修复率次之(83%)，下壁外缘修复率最低(43%)。

结论：不同手术位点的修复对于手术效果的影响是不同的，其中后隅角的修复对手术效果作用最大； 手术中对重要位点的关注可以指导手术操作，减小手术风险。

METHODS: The date of 23 eyes of 23 cases with medial-inferior orbital wall fracture with enophthalmos were collected and analyzed retrospectively. All cases underwent orbital fracture surgery, the follow-up time was 3mo. After surgery, the degree of enophthalmos was within 2mm. The repair of bony buttress, exterior margin of inferior orbital wall, and superior margin of medial orbital wall after surgery were analyzed.

RESULTS: In these well-recoverd patients, repair rate between bony buttress(100%), exterior margin of inferior orbital wall(43%)and superior margin of medial orbital wall(83%)were different.

CONCLUSION: The repair of bony buttress was most important for surgery. Analysis between surgical efficacy and edge points repair is valuable for surgical operation and risk control.
