Application of surgical navigation technique in traumatic orbital wall defect reconstruction / 实用口腔医学杂志

ABSTRACT

Objective: To evaluate the effects of surgical navigation technique in the reconstruction of traumatic orbital wall defect.Methods: 20 patients underwent the operation with the aid of navigation for repairing traumatic orbital wall defect as the test group. 20 patients were treated without navigation as the control group. Treatment outcome was evaluated by correction of exophthalmos, orbital volumes and patient's self-satisfaction. Results: The mean difference of eyeball protrusion between the reconstructed and the unaffected orbit cavity in the navigation group and control group was (0. 81 ± 0. 35) mm and (1. 65 ± 0. 37) mm (P ＜ 0. 05), that of the orbital volume (0. 68 ± 0. 29) ml and (0. 98 ± 0. 22) ml (P ＜ 0. 05), respectively. The patient's satisfaction value of the navigation group was higher than in the control group (P ＜ 0. 05) . The operation duration in the navigation group was less than in the control group (P ＜0. 05) . Conclusion: Surgical navigation can improve the accuracy and the effects of operation for orbital defect reconstruction.
