Abstract
Introduction: Human orbit is a complex anatomical region, comprising visual apparatus along with its neurovascular structures. Morphometric analysis of orbit is of significant value for anthropologists, anatomists, forensic experts and surgeons. The objective of this study was to provide gender-related data on various orbital parameters in the North Indian population, and to compare the results with previous authors. Materials and Methods: The orbital dimensions of 86 dry adult skulls (45 males and 41 females) were used for direct measurement with vernier caliper. The calculation was carried out on both the right and the left sides. All the data obtained were tabulated and statistically analyzed. Results: The mean orbital height for males and females was 32.53 ±2.00 mm and 32.43 ±1.57 mm while the mean orbital width was 39.98 ±1.81 mm and 39.37 ±1.65 mm, respectively. The mean volume of the bony orbit was 26.09 ±2.15 ml in males, and 24.04 ±2.30 ml in females. Orbital index was calculated by using the formula Ht /Br x 100. The mean orbital index was 81.51 ±6.11 mm and 82.54 ±5.38 mm in males and females respectively, which classified both genders in the microseme category of orbit. There was no statistically significant difference observed between the right and left side of the orbital parameters. Conclusion: Comparison of findings with earlier research reveals that the anatomical character of the orbital cavity differs greatly, not only because of the diversity of the parameters used, but also because of ethnic variations, different methods of measurement and sample size. Data collected in the present investigation could serve as a baseline orbital morphometric data for the North Indian population, which is very useful during plastic surgery, maxillofacial and neurosurgery, as well as in forensic science.
