Craniofacial superimposition technique was used for identification, when a skull of a missing person isrecovered, by comparing with ante-mortem photographs or video. Parameters like inter-pupillary distanceand bizyomatic width/ facial width of the human face are used in the superimposition technique in orderto identify a missing person. The study was conducted to find out the mean facial width and mean interpupillarydistance separately in both males & females and correlation between these parameters. This studywas conducted in 100 healthy subjects (50 males & 50 females) in the age group of 19 to 22 years at theHimalayan Institute of Medical Sciences, Uttarakhand. Interpupillary distance (IPD) and facial width (FW)were measured by means of vernier callipers. The data was compiled and analyzed by computer softwareSPSS version 20. Among the females, descriptive analysis of quantitative data showed that the mean IPDwas 4.8272 ± .37395, mean FW was 12.4240 ± .69151 and Pearson Correlation coefficient was 0.168.Among the males, mean IPD was found out to be 5.9365 ± 0.37072, mean FW was 16.8290 ± 1.11108 andPearson Correlation coefficient was 0.216. The mean value of both, IPD and FW were higher in males ascompared to females.A weak correlation was found in both sexes and no statistically significant correlation was found in facewidth and Interpupillary distance in both males and females as the p value for male was 0.133 and for femaleit was 0.245.
