Clinical study of computer-assisted prefabricated titanium mesh for reconstruction of complex orbital fracture

Abstract

Objective To explore the safety and efficacy of computer-assisted prefabricated titanium mesh for overall repairing orbital wall and rim in complex orbital fracture patients.Methods Fifteen patients were included in this study.All patients suffered from complex orbital fracture.Group A included 5 patients who were reconstructed for the complex fractured orbital wall and rim with Hydroxyapatite.Group B had 10 patients treated with computer-assisted fabricated titanium mesh.The efficacy of computer-assisted prefabricated titanium mesh for complex orbital fracture was evaluated by postoperative measurements of diplopic figures,exophthalmos and changes of orbital capacity obtained by CT on postoperative week 2 and monrth 3,and 6.Results The cure rate of Enophthalmos after operation:2 weeks:group A was 60％,group B was 80％,and the cure rate both the same in 3 months and 6 months after operation:groupA was 40％,group B was 70％.The enlargement volume of orbit in Postoperative was decreased.The mean value of group A was 3.1 ml.Group B was 3.7ml.The cure rate of diplopia:2 weeks cure rate:group A:20％,group B:50％,3 months:40％ of group A,group B:60％,6 months:40％ of group A,group B:70％.There was no vision loss,graft extrusion,rejection,infection and other complications in all patients after operation.Conclusions Computer-assisted prefabricated titanium mesh introduced into the overall plastic surgery of complex orbital fracture can provide more accurate orbital reconstruction and improve the correction of enophthalmia and diplopia.
