A COMPARATIVE MORPHOMETRIC STUDY OF ORBIT- IN NORTH INDIAN DRY SKULL

Background: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 north Indian population. Materials and Methods:The study involved 215 dry skulls (83 female & 132 males) from the department of anatomy from GSVM Kanpur, KGMC Lucknow, SMC Unnao.Orbital height (OH), orbital width (OW) has been taken of both side skulls in male and female.Orbital index (OI) was calculated by OH/OW × 100= OI.All these measurements are taken by digital vernier caliper.Result: Mean orbital height in male skull was 33.8 ± 1.27, while female skull was having 31.2 ± 0.98.Orbital width was 42.64 ± 2.16 in male and 40.85 ± 2.08 was measured in female and the orbital index was 83.45 and 77.96 in male then after in female and these all values are found to be statically highly significant.While comparing the right and left sided skull the height was 32.37 ± 1.08, 30.96 ± 0.85 while breadth was 40.31 ± 2.28 and 40.28 ± 2.02 and the orbital index was 80.75 ± 5.60 and 80.67 ± 5.31 founded only orbital height have highly significant value and width and index having nonsignifacant value. Conclusion:We can conclude by our study that right orbit and male orbits have higher values In comparison to opposite side and sex having more value.Study also tells that male skull Is categorized under mesoseme and female in microseme categories of north Indian populations.It is recommended that further population based studies be carried out in different geographical locations.
