Abstract
Introduction: Orbit lodges important structures for vision and allows passage of fine neurovascular structures in it. The knowledge of orbital morphometry helps to protect those structures during various surgical procedures.
Aim: To determine the morphometry of bony orbit in dry South Indian skulls related to gender and to compare the results with previous authors.
Material and Methods: The material of the present study consists of 100 orbits from 50 skulls (right & left) which are identifiable of their sex. Foetal skulls and skulls with damages in the area of measurement were excluded. All the parameters were examined by a single observer using a vernier calliper, divider and millimetre scale. In each wall of the orbit, a bony landmark is chosen from where the distance of other bony structures is measured.
Result: The result of the present study showed significance with respect to gender and side.
Conclusion: The data of the present study will be helpful for various surgical approaches around the orbit.

Key words: orbit, South Indian skulls, morphometry.
