Abstract

Background: The human orbit is a complex anatomic region, which plays predominant role in the evaluation of craniofacial complex. The bony orbit which lodges the visual apparatus is important not only for anatomists but also for ophthalmologists, oral and maxillofacial surgeons and forensic experts. The objectives of the present study are to provide the normal reference orbital parameters for the South Indian population.
Materials and Methods: The study was done on 200 skulls (105 males and 95 females). The orbital height (Ht) and breadth (Br) were measured by using manual vernier caliper. Orbital index was calculated by using the formula Ht /Br х 100. All the data obtained were tabulated and analysed statistically by computing descriptive statistics like mean, standard deviation and range. Mann-Whitney test was done to find out the statistical significance of all parameters of orbits, with respect to gender and side (right and left side).
Results: The results showed that the height and breadth were significantly larger in males than in females. There were no significant differences in height and breadth between the right and left side orbits. There was no significant difference in OI between the genders and also sides. According to the OI, the studied group of Indian population comes under Mesoseme category.
Conclusion: This study provides useful baseline orbital morphometric data of south Indian population, which are very important during plastic surgery, maxillofacial and neurosurgeries and also in the forensic research.
KEY WORDS: Dry skull, Orbital dimensions, Orbital index.
