Abstract:
Orbital fractures are increasing in frequency with the rise in number of automobile accidents and the development of industries. It may be difficult to detect fractures with plain X-rarys of the orbit, because of the superimposition of the shadow by bony structures. Even minor alterations in head position can cause a significant change of shadow. Computed tomography is extremely accurate and can be diagnostic with respect to the location and size of the fractures, because it provides detailed visualization of both the bones and soft tissues of the orbits. We studied 89 patients with orbital fractures proven by computed tomography and the results are as follows: 1. Orbital fractures occurred most frequently between the ages of 11 and 40 years. 2. The causes of orbital fractures were traffic accidents(46.1%), contact with human bodies(24.7%), fall-down injuries(14.6%) and others(14.6%). 3. There was no significant difference in the incidence of orbital fracture between the right and left eyes. 4. In single wall fractures, medial wall fractures were most common, followed by factures of inferior, superior and lateral walls in order. 5. In combined wall fractures, medial and inferior wall fractures were most common.
