“…Also, the differing paediatric anatomy may be relevant as there is a steeper orbital floor angle and it has been observed that the most inferior point on the orbital floor shifts posteriorly with age. 26 It is acknowledged that this sample of isolated orbital floor fractures is limited, but our experience supports the recommendation that exploration of symptomatic orbital floor 'trapdoor' fractures be undertaken as soon as possible on presentation to minimize the risk of longterm diplopia due to extraocular muscle damage.…”

“…On the other hand, orbicularis oculi, corrugators supercilii, and extraocular muscles arise from an orbit. The muscle activity of these muscles decreases as age increases, which causes the retrusion of the orbit [16] , and the change in this bony architecture is expected to be more significant in women than in men [17] . For these reasons, it can be said that the orbital volume decreases with age increase and the rate of decrease of the orbital volume is greater in women than in men.…”

Aims: To measure the orbital volume of normal Korean people in two different age groups (subjects were in their 20s or 40s), and analyze the differences of orbital volume with respect to age and gender. In addition, to analyze correlation between body parameters (height and weight) and the orbital volume. Methods: Magnetic resonance imaging (MRI) data were acquired for a total of 143 subjects, consisting of 71 subjects in their 20s (32 males and 39 females) and 72 subjects in their 40s (30 males and 42 females). Two-way ANOVA was used to analyze how orbital volume changes with respect to gender and age. A multiple regression analysis was performed to investigate the correlation between body parameters and the orbital volume. Results: The orbital volume of subjects in their 20s was larger than that of subjects in their 40s, and the volume was larger in men than in women. As age increased, the decrease in the orbital volume of women was greater than that of men. While weight and height showed positive correlations with orbital volume in male and female subjects in their 20s, respectively, weight showed a positive correlation with orbital volume in male and female subjects in their 40s. Conclusions: These results provide basic information about the effect of age, gender, and body parameters on orbital volume of Korean people in their 20s or 40s.

“…Such treatment restores the structure of the orbit and prevents late complications (Hammer and Prein, 1995;Nagasao et al, 2007). A series of methods and different materials have been described in the literature (Parsons and Mathog, 1988;Hammer and Prein, 1995;Eufinger et al, 1998;Burnstine, 2003;Hoffmann et al, 2004;Potter and Ellis, 2004;Buchel et al, 2005;Burm, 2005;Metzger et al, 2006;Schön et al, 2006).…”
