Abstract OBJECTIVES: To compare and evaluate, using computer-aided volumetric measurements, the accuracy and reliability of nonpreformed mesh plates (NPMPs) versus 3-dimensionally preformed titanium mesh plates (PMPs) in posttraumatic orbital volume restoration. PATIENTS AND METHODS: Facial coronal computed tomographic scan slices from 20 patients (10 in the NPMP and 10 in the PMP group) were used to measure bony orbital volume using OsiriX Medical Image software (version 3.3.2, www.osirix-viewer.com). The procedure was performed on both orbits; thereafter, the volume of the contralateral health orbit was used as a control for comparison in the 2 groups of patients. The difference in orbital volume between the 2 groups and between the reconstructed versus uninjured side in both groups have been statistically correlated. RESULTS: The mean orbital volume between the reconstructed (19.215 mL in NPMP and 21.791 mL in PMP) and the contralateral uninjured side (18.955 mL in NPMP and 21.710 mL in PMP) was not statistically significant (P > 0.05). The mean orbital volumes of the reconstructed orbits were 19.215 mL in the NPMP and 21.791 mL in the PMP group, with no statistically significant difference (P > 0.05). The volume data of the reconstructed orbit fitted that of the contralateral uninjured orbit with an accuracy of a maximum of 1.85 mL in the NPMP group and 2.5 mL in the PMP group. CONCLUSIONS: The current study demonstrated that there were no significant differences in the orbital volume restoration using either technique. In fact, both techniques allow for close reproduction of natural orbital volume and shape, and its use in posttraumatic orbital wall reconstruction was successful.
