[Correction of enophthalmos following orbital fracture with computer-assisted navigation system].

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.
