Abstract

The purpose of this study was to develop and validate a technique for objective quantitative evaluation of outcomes of orbital reconstruction. Facial three-dimensional images were captured using a Vectra three-dimensional camera. Morphometric analysis was based on interactive anthropometric identification. The analysis was applied to a population of healthy adults (n = 13) and a population of patients following primary repair of unilateral orbital fractures (n = 13). Morphologic results following reconstruction were evaluated by identifying residual asymmetries. All subjects further completed the Derriford Appearance Questionnaire and the Orbital Appearance and Function Questionnaire.Normative reference values for periorbital asymmetry were determined in a reference population. The mean asymmetry was less than 1.6 mm for each measured morphologic feature. In the trauma population, primary orbital reconstruction effectively restored normal periorbital symmetry in 16 of 20 measured parameters. The fracture population showed no significant differences in the degree of asymmetry in globe projection, lower eyelid position, or ciliary margin length.The overall DAS59 scores were significantly higher in the fracture population (P = 0.04). This was due to significantly higher physical distress and dysfunction scores (P = 0.02), as well as a trend toward higher general and social self-consciousness scores (P = 0.06). No significant difference in facial self-consciousness was noted (P = 0.21). Thus, although primary orbital reconstruction was effective in restoring periorbital morphology, patients still experienced a higher level of physical distress and dysfunction than their nontraumatized counterparts. This was in accordance with patient self-report, which indicated that a greater percentage of patients were significantly bothered by functional outcomes postoperatively as opposed to appearance.
