Aim: Is to evaluate the accuracy of orbital volume correction using pre-adapted titanium mesh with the aid of stl model of corrected orbit.
Patients and methods: Ten patients with unilateral orbital floor fracture were included. The cases were divided into two equal groups. Manual group where titanium mesh was manually adapted intra-operatively. STL group where titanium mesh was adapted pre-operatively using stl model of corrected orbit. Orbital volume measurements based on CT images were used to trace the degree of correction in each group. Paired samples t test was used for statistical analysis.
Results: There was statistical significant difference in the correction of orbital volume in each group. However, comparison between the two groups revealed no statistical significant difference in the percentage of correction, where the mean percentage of correction in stl group was (102.8 ± 4.4) versus (98.4± 2.6) in the manual group.
Conclusion: Application of pre-adapted titanium mesh by the aid of stl model provide successful tool for correction of orbital volume secondary to orbital floor fracture with less operative time and effort especially in comminuted fractures.
