- Abstract
Purpose: The present study aims to investigate how well CT images correlate to surgical findings in orbital floor fractures and to the presence of diplopia. Methods: In this cross-sectional study, 27 consecutive patients already selected for surgery due to an orbital floor fracture underwent a routine CT scan (axial, coronal, sagittal). An ophthalmologist established any presence of diplopia. Extent of fracture/injury seen on CT was compared to that discovered during surgery. Results: In the surgeons´ opinions CT-images were in concordance with surgical findings in 71% of the cases. Agreement for pure blow out fractures was high (92%). Tetrapod fractures as a cause of an orbital floor fracture was only identified as such by surgeons in three of 11 cases, all subjected to orbital exploration, not only a closed reduction. Diplopia showed a significant correlation to rounding of the inferior rectus muscle at coronal CT. "Rounding" significantly correlated with the presence of a floor defect, to herniation of soft tissues and to the volume of displaced tissue. Conclusions: The results imply that the joint professional interaction between neuroradiology and surgery is important and would benefit from the use of an easy and well-defined classification system of orbital floor fractures. In Sweden a national record to collect data on all zygomaticomaxillary complex fractures assessed is to be started aiming at making general statements possible by time.
