Clinical and Radiological Evaluation of Enophthalmos and Orbital Volume Changes in Zygomaticomaxillary Complex...

A prospective study was performed on thirty-eight patients reported with recent isolated unilateral Zygomaticomaxillary complex fractures to evaluate clinical and radiological enophthalmos with orbital volume changes. Enophthalmos was measured clinically and radiologically with Hertel's exophthalmometer and axial section of CT scans respectively. Three-dimensional reconstruction and volum measurement of the orbital cavity were also done using the software Advantage workstation 4.7. The correlation between the three variables clinical, radiographic enophthalmos and volume of the orbit were measured by Pearson's correlation coefficient analysis. Linear regression analysis was applied to evaluate the association between enophthalmos and volume change of the orbit.The amounts of clinical and radiological enophthalmos were positively co-related. They were also positively correlated with the orbital volume change. From the linear regression analysis, it can be interpreted that, for each 1 cm3 of orbital volume change,clinical enophthalmos changes will be 0.127 mm whereas radiographic enophthalmos will be 0.227mm.
