Abstract

OBJECTIVE

To evaluate the efficiency of individually fabricated titanium mesh to correct enophthalmos following orbital fracture by using computer-assisted navigation system.

METHODS

Forty- nine patients with unilateral orbital fracture were divided into navigation group (25 cases) and non-navigation group (24 cases). All patients underwent orbital reconstruction to correct post-traumatic enophthalmos with individually fabricated titanium mesh. The bilateral global projection and the orbital volumn were measured preoperatively and postoperatively. The depth of titanium mesh was measured postoperatively.

RESULTS

Statistical analysis demonstrated the global projection at the affected side increased by (3.35 ± 1.46) mm in navigation group and by (2.25 ± 1.14) mm in non- navigation group postoperatively, and there was a significant difference between the two groups (P < 0.05). The orbital volumn at the affected side decreased by (5.94 ± 2.20) ml in navigation group and by (4.21 ± 2.18) ml in non-navigation group, and there was a significant difference between the two groups (P < 0.05). The depth of titanium was (31.95±2.97) mm in navigation group and (29.27±2.72) mm in non-navigation group, and the values between the two groups differed significantly (P < 0.05).

CONCLUSIONS

The use of computer-assisted navigation for the orbital wall reconstruction with individually fabricated titanium mesh can protect the optic nerve reliably and achieve satisfactory results.

摘要

目的

通过计算机辅助导航系统评估个体化制作钛网矫正眼眶骨折后眼球内陷的效果。

方法

将49例单侧眼眶骨折患者分为导航组（25例）和非导航组（24例）。所有患者均采用个体化制作的钛网进行眼眶重建以矫正创伤后眼球内陷。术前和术后测量双侧眼球整体投影及眼眶容积。术后测量钛网深度。

结果

统计学分析显示，术后导航组患侧眼球整体投影增加（3.35±1.46）mm，非导航组增加（2.25±1.14）mm，两组间差异有统计学意义（P<0.05）。导航组患侧眼眶容积减少（5.94±2.20）ml，非导航组减少（4.21±2.18）ml，两组间差异有统计学意义（P<0.05）。导航组钛网深度为（31.95±2.97）mm，非导航组为（29.27±2.72）mm，两组间差异有统计学意义（P<0.05）。
