Orbital Fractures with Enophthalmos (PFE)

To determine whether orbital volume assessment by computerized tomography (CT) could provide additional information for the initial evaluation of orbital blowout fractures and guide optimal treatment. The medical records of 30 patients with orbital blowout fractures, either surgically or conservatively managed, were retrospectively reviewed. Orbital volumetric analysis was then determined from digitized CT scans. Fracture-related volume expansion relative to the unaffected fellow orbit was correlated with motility deficits and location and degree of enophthalmos. CT measurements of orbital volume can predict the final degree of late enophthalmos and may facilitate the planning of surgical intervention.
