Design: A retrospective cohort study. Subjects: Healthy Caucasian children (ages 6–18 years) with existing serial craniofacial cone-beam computed tomography scans. The final sample consisted of 65 subjects (24 male, 41 female) and a total of 300 separate orbits. Methods: Each orbit was transformed into a closed space with well-defined boundaries, and orbital volume was measured using manual segmentation. A novel statistical analysis was applied to extract the maximum amount of longitudinal information from the data. Intra- and inter-operator correlation coefficients were calculated from replications performed on 10% of the sample. Main Outcome Measures: Orbital volume (mm3). Results: Orbital volume was found to increase at a rate of 1–2% annually until the late teenage years. Intra- and inter-operator agreement between repeated measurements were >90%. Conclusions: Orbital volume increases by 1–2% per year throughout childhood continuing until the late teens. Although this annual increase is small, it may be clinically relevant as it may lead to less-than-optimal long term surgical outcomes when reconstructive surgery for the pediatric anophthalmic socket is required.Item Spatial distribution of Minnesota's mature hardwood inventory for 1980, 1990, 2000 and 2010.(University of Minnesota, 1982) Williams, James T.; Smith, Eric; Rose, Dietmar
