【 摘 要 】

Objective: The aim of this study is to evaluate the use of mastoid process as a tool for sex determination in unidentified skeleton.Methods: Eighty (40 male and 40 female) complete undamaged skulls of known sex in book record were used for the study. Eight different measurements on the right mastoid of each skull were recorded. Measurements were made using vernier calipers (0.01mm). The values were subjected to univariate and multivariate analysis employing SPSS Windows 13.00 version program.Results: Statistics revealed high significance (p<0.000) in five measurements except Asterionporion, Posterior end of incisura mastoidea - depression of suprameatal triangle and Asterion-depression of suprameatal triangle. Direct method with all parameters gave discrimination accuracy of 82.5% and in step wise analysis an accuracy of 65.0%. Stepwise analysis selected MastoidalePorion as the best discriminant.Conclusion: Reports on the use of mastoid process as a tool for sex estimation in unidentified human skeleton has been reported in different populations. The present study supports this finding among the South Indian population.
