Materials   and   Methods:   The   study   was   performed   on   98   adult   Indian   skulls   (196   orbits)   consisting   of   60   male   and   38   female   skulls   ofknown   age   and   sex. Parameters   measured   were   Orbital   height   (OH),   Orbital   breadth   (OB)   and   Orbital   Index   (OI)   which   were   expressed   in   descriptive   statistics   i.e.   mean,   range and standard deviation. Results:    In   the   present   study,   in   males,   the   mean   OH   for   the   right   and   left   sides   were   32.64±2.07   and   32.39±2.18mm   respectively   while   their   OB   were 37.52±1.35   and   37.08±1.96mm   respectively   and   the   mean   OI   was   87.47.   In   Females,   the   mean   OH   for   the   right   and   left   sides   were   32.55±1.91   and 32.31±1.55mm respectively while their OB were 37.25±1.64 and 36.67±1.56mm respectively and the mean OI was 87.88. Conclusion:    The   mean   OI   in   the   present   study   was   87.47   placing   the   Indian   population   in   Mesoseme   group.   Difference   in   orbital   breadth   on   two   sides   was statistically significant emphasizing bilateral asymmetry. However the gender differences in OH, OB and OI were statistically insignificant.   KEY WORDS: Orbital Height, Orbital Breadth, Orbital index; Morphometry; Sexual dimorphism; Skull. References 1 .
