Abstract
Computed tomographic (CT) findings in four patients with isolated blow-out fracture of the medial orbital wall are reported. CT delineated the fracture site and its extent in each case, and clearly demonstrated medial rectus muscle entrapement in two. This was confirmed by surgery. CT was found superior to poly tomography and proved to be the best radiologic means for the diagnosis of medial orbital wall fracture and muscle entrapment.
