Abstract
Introduction: Each orbital cavity is actually meant as a socket for the eyeball. The human orbit is a complicated anatomic area, which performs predominant position in the craniofacial complex.
 Aim: The aim of the study is to provide the normal reference orbital parameters for the south Indian population.
 Materials and Methods: The present study has adopted 30 south Indian dry skulls. An orbital cavity was measured using vernier callipers. With the help of vernier calliper and ruler, the measurements such as length, breadth of the orbital cavity and biorbital breadth, interorbital breadth of the orbital cavity were measured. The paired t-test is the statistical method used in this study.
 Results: The mean orbital breadth of the right orbit is 34.6±1.777 and left orbit was 34.701±1.711
 The mean orbital height of the right orbit is 33.417±1.494 and the left orbit is 33.38±1.560. The mean biorbital breadth of the orbital cavity is 94.16 ± 2.533 and means interorbital breadth of the orbital cavity is 20.615±1.172. Paired t test demonstrated no significant statistical difference between the right and left orbit.
 Conclusion: The orbital cavity additionally used for determination of sex and ethnic courses of a cadaver and its phase of the cranium that posses manipulate over sexual dimorphic traits.
Highlights
Each orbital cavity is meant as a socket for the eyeball
The associated muscles, nerves, vessels, and the visual apparatus are enclosed in the eyeball which is intended as a socket in the orbital cavity for its protection [1]
The bony orbit were made in the combination of seven bones frontal bone, lacrimal bone, ethmoid bone, zygomatic bone, maxillary bone,palatine bone and sphenoid bone [4]
Summary
Each orbital cavity is meant as a socket for the eyeball. Aim: The aim of the study is to provide the normal reference orbital parameters for the south Indian population. An orbital cavity was measured using vernier callipers. Conclusion: The orbital cavity used for determination of sex and ethnic courses of a cadaver and its phase of the cranium that posses manipulate over sexual dimorphic traits. The orbit is a complex anatomic region of our human body. The bony orbits or eye sockets were bilateral and symmetrical cavities. The associated muscles, nerves, vessels, and the visual apparatus are enclosed in the eyeball which is intended as a socket in the orbital cavity for its protection [1]. The aim of the study is to determine the normal reference orbital parameters of the south Indian population [5]
