Introduction: Each individual on the surface of this earth has unique anatomical features which distinguishes him from others. Among such unique features, cephalo-facial characters are the most commonly used parameters employed for personal identification. Though cephalo-facial anatomy of one ethnic group differs from another, yet within the same ethnic group it may experience diachronic change. Few works have been carried out specifically on cephalo-facial features of some selected population groups of India. But no such exhaustive study has been carried out on the Meiteis of Manipur valley from a diachronic approach. Aims and Objectives: The present work aims at profiling a database of the cephalic anatomy of the Meitei adult male population of Manipur on one hand and diachronic comparison of the present findings with the findings of Singh (1992) who carried out a similar work almost three decades back from now with a view to examine if there is any secular micro-evolutionary change taking place in cephalic on the other. Methodology: The present study is conducted on randomly selected 1600 Meitei adult males of Manipur valley whose age range from 21 to 60 years. Two direct cephalo-facial measurements i.e. maximum head length and maximum head breadth have been measured employing Weiner and Lourie (1969) technique and corresponding cephalic index was calculated and classified according to the conventional categories of Labzelter and Saller (1968). Results: Based on the findings of the measures of cephalic dimensions, Meiteis dominantly have medium to long head length and head breadth with an overall head shape ranging between mesocephalic to brachycephalic. The findings reveal that among the adult Meitei males, both maximum head length and maximum head breadth have increased from the last generation to the present generation. While the cephalic index index of the present generation have lower mean value than the previous generation showing statistically significant difference. Conclusion: The present findings therefore reveal a positive secular change towards increasing head length and head breadth while a negative secular trend in cephalic index. The database derived from the findings of the present study shall definitely have clinical applications in the field of cranio-facial surgery as well as in forensic application particularly in personal identification and of cranial reconstruction of the victims of the said ethnic community.
