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.
