Abstract

We compared the diagnostic accuracy of the simple x-ray with that of the computed tomography, and analyzed the surgical results according to the timing of operation in 52 patients with suspected orbital blowout fractures who complained diplopia after midfacial trauma. Of all the cases, 40 orbital fractures were confirmed with CT and forced duction test and the remaining 12 patients were thought to have transient functional impairment because the clinical signs were resolved with time. CT detected all the 40 actual fractures, so the dignostic accuracy(100%) was higher than that of the simple x-ray(75%) which detected 30 fractures of the 40 actual fractures(p=0.001). We operated 19 patients who have persistent diplopia, enophthalmos of more than 2 mm, and large fracture defect, and there was significant improvement of symptoms and signs in patients on whom operations were performed within 2 weeks after trauma rather than after 2 weeks.
