Computerized Tomography for Evaluation of Fractures and Foreign Bodies of the Orbit
Orbital trauma may injure soft tissues, damage the facial bones, and imbed foreign bodies. Injury may also occur to structures adjacent to the orbits, leading to cerebrospinal fluid leaks, carotid-cavernous sinus fistulas, and damage to the brain, nasolacrimal pathways, or paranasal sinuses (Smith et al., 1976; Grove, 1977). Because of the difficulty in determining the extent of soft tissue injuries in patients with orbital fractures, and in localizing intraorbital foreign bodies, computerized tomography has been used to aid in the management of patients with mid-facial injuries (Grove, 1977; Grove et al., 1974, 1977; Momose et al., 1975; Kollarits et al., 1977).
