Introduction: Anatomy of Human Orbit is complex, which plays main character in the assessment of craniofacial complex. The bony orbit which lodges the Eye ball is significant not only for anatomists but also for oral and maxillofacial surgeons, forensic experts, ophthalmic surgeon, and Neurosurgeon. The main objectives of the existent study to specify the common location orbital parameters of the Maharashtrian population.

Materials and Methods: 31 dry human skulls were taken for observational study from department of anatomy IIMSR Warudi, Badnapur. All skulls were adult type. The exact age and sexes of the skulls were not known. Those were used for tutorial teaching for medical students.

Measurements: The measurements for dimension of orbital cavities were taken with the help of manual Vernier Caliper.

Orbital Length: This indicates distance between superior and inferior margin of orbital fossa.

Orbital Breadth: Distance between medial and lateral walls of orbital fossa (from frontal process of zygomatic arch to frontal process of maxilla.

Orbital Index: Calculated as Orbital length/Orbital Breadth X 100. Measurements were recorded and expressed as Mean± Standard Deviation and range (Min. value – Max. value of each measurement).

Results: The results indicate that right orbital length displayed (33.70 ± 1.20 mm) and right orbital Breadth exhibited(38.90 ± 2.20 mm). From these consequences, orbital index was estimated as orbital length/Orbital breadth x 100. A mean orbital index of right side 86.63mm and left side 85.99mm was deduced (Table 1). The assessment of figures from pair of orbits by paired t test shows statistically significant difference in orbital length (p=0.021) and orbital index (p=0.011). Whereas, Orbital breadth has not shown statistically significant difference (p=0.25).

Conclusion: This study specifies valuable reference orbital morphometric facts of Maharashtrian population, which are very significant throughout the Maxillofacial Plastic surgery, neurosurgery forensic research and Ophthalmological procedures.

Keywords: Dry skull, Orbital dimensions, Orbital index.
