Subtle diagnostic markers of orbital floor blow-out fracture on coronal CT scan.

The sagittal plane, computerized tomography (CT) scan has been proposed as the most important radiological view in the diagnosis of orbital floor blow-out fractures. This view however is impractical and unnecessary. Direct, coronal plane CT scan with careful attention paid to the shape of the inferior rectus muscle and antral roof will successfully diagnose this traumatic condition, as in our reported case in which no other radiological abnormalities were present.
