To determine the sex the skull and skeletal plays an important role for the archeologists, physical anthropologist, and forensic anthropologist. To gain by using the knowledge of osteology of human anatomy. Due to its anatomical position of mastoid process at basolateral region of skull so it is the most dimorphic bone which it is least damaged. The parameters of mastoid process are larger in males than in females. In present study to determine the sex in unidentified skulls an attempt has been made to evaluate the use of mastoid process measurements. For that to test the accuracy of sex determination using discriminant function analysis. Material and Method; this study is carried out in department of anatomy D.Y.Patil Medical college, Kolhapur. A total sample size is 100 adult human dry skulls (50 Male 50 Female) were studied to determine the accuracy of sex of mastoid process. The Mastoid length, antero-posterior diameter, medio-lateral diameter and to calculate the mastoid index. Also the distance between, asterion to mastoidale, asterion to porion, Porion to mastoidale 1 were studied. Results; in the present study we observed that, out of seven mastoid variables, six variables are more in males as compare to females. The difference observed for six variables if mastoid process was statistically significance (p<0.005). The discriminant function analysis revealed that mastoid process is correctly classified for the sex in 75% of left side skull and 60% of right side skull subjects1. And mastoid length, ast-ms, ast-po, po-ms was found to be excellent discriminant function analysis for sex. The present study provides the baseline data for determination of sex of mastoid process of skull.
