Abstract

Aim: Many of the anatomical structures of the cranium are used for gender determination. The aim of this study is to evaluate the usability of five angles belonging to the bone structure seen from the midsagittal plane with Computerized Tomography (CT) in determining gender.

Materials and Methods: Retrospectively, midsagittal CT images of 99 male and 101 female, a total of 200 people were examined. Five different angles were measured on the midsagittal bone structure. The results were evaluated statistically.

Results: It was determined that two angles, Rhinion-Spina Nasalis Anterior- Prosthion angle and Nasofrontal angle, could be used for gender determination with respectively 95.3% and 100% reliability. Rhinion-Spina Nasalis Anterior-Prosthion angle mean 135.75±8.68 degrees in male and 138.31±9.33 degrees in female, nasofrontal angle mean 119.64±10.10 degrees in male and 131.22±10.24 degrees in female were ascertained and the mean of both angles was significantly greater in women.

Conclusion: Our study shows that the Rhinion-Spina Nasalis Anterior-Prosthion angle and the Nasofrontal angle on the CT midsagittal bone image can be safely used for gender determination in anatomical, anthropometric and forensic studies.

Keywords: craniofacial bone, midsagittal, angles, determine, gender.
