Abstract
Objective: This study aimed to evaluate the validity of the mastoid triangle anthropometric measurements and area between the three craniometric points, namely porion (po), asterion (ast), and mastoidale (ms) as a sex determinant. Materials and Methods: A total of 60 dry skulls (30 males and 30 females) were assessed for 10 morphometric measurements with a compass, and a total of 120 mastoid triangles were evaluated. Results: Statistically significant differences were found in all the mastoid triangle measurements between males and females (p≤0.01). Discriminant function analyses revealed that the left po-ms length and the total area of the mastoid triangle were two variables with the highest sensitivity at an accuracy rate of 90%. The models with three mastoid triangle variables including the total po-ms, total ms-ast, and total po-ast measurements, in combination, provided high discriminant potentials of 96.7% and 93.3% in females and males, respectively. When the total po-ms, total ms-ast, and total po-ast were used together, a greater sexual dimorphism was observed, correctly classifying the sex with a 95% accuracy rate. The mean value of the total area which is preferred due to the asymmetry between the sides of the skull was 1455.2 mm² in males and 1341.2 mm² in females. Conclusion: In the light of the obtained results, the discriminant function analyses of the mastoid triangle measurements are concluded to be reliable in sex determination and preferable in forensic medicine and anthropology.
