Abstract
BACKGROUND
The orbits are four-sided pyramidal cavities present in normal frontalis in skull. We wanted to evaluate the sexual dimorphic morphometry of orbit in skull bones.
METHODS
45 adult dry skulls of both genders were studied. Parameters such as orbital height, orbital breadth, orbital index (OI = height of orbit / orbital breadth x 100), orbital rim perimeter, orbital opening area (22 / 7 x AB where A and B are the halves of orbital height and breadth respectively) were recorded.
RESULTS
Out of 45 skulls, 25 were of males and 20 were of females. The mean orbital height was found to be 35.4 3.8 mm and 33.4 +/- 3.4 mm in males and females respectively, orbital breadth was 43.7 +/- 4.3 mm and 42.1 +/- 4.1 mm in males and females. The mean value for orbital index in males was 84.2 +/- 7.1 and in females was 81.6 +/- 8.2, orbital rim perimeter in males was 12.6 +/- 2.5 cm and in females was 11.3 +/- 2.2 cm, 12.4 +/- 2.1 cm2 and 11.1 +/- 2.0 cm2 was orbital opening area in males and females. It was found in the study that the mean bony orbital volume in males was 28.8 +/- 3.4 mL and in females was 25.2 +/- 3.2 mL. A non-significant p value (p 0.05) was obtained. Round shaped orbit was seen in 9 males and 16 females and square shaped orbits in 14 males and 6 females. A non-significant difference was seen (p < 0.05).
CONCLUSIONS
Authors found that average orbital parameter measurements were more in males as compared to females with significant difference.
