Gender Related Changes of Bizygomatic Diameter, Maxilla and Foramen Magnum in Different Age Groups Background: The purpose of this study was to assess the relationship between gender and the measurements/evaluations acquiered from skull base on cone beam computed tomography images in people at different decades.Methods: The study was performed on 100 CBCT images of the subjects in five different decades (age-ranged between 20-29, 30-39, 40-49, 50-59 and 60-69). A classification in eight categories was used for the categorisation of foramen magnum type. The dimensions of foramen magnum and maxillary alveolar region measured transversally and sagitally. Byzigomatic width measured transversally. The evaluations were repeated twicely. Data was analyzed in IBM SPSS Statistics 21.0. For statistically significance, p<0.05 was accepted as criteria.Results: In males "hegzagonal" type, in females "egg shaped" type was the most common forms. However, gender has no effect on the distribution of foramen types (p=0.841). Statistically significant difference was found between gender and all other measurements (p<0.05 for each one). Conclusion:The importance of radiologic data in forensic sciences is increasing. It was observed that data obtained from CBCT was compatible with data achieved from anatomic and CT studies using for determination of gender. It is foreseen that oral and maxillofacial radiology has an important contribution not only in the diagnosis of diseases, treatment and following of prognosis but also in forensic sciences.

“…Therefore, it is more suitable for the stability of sexually dimorphic traits, and it is the most frequently used body region for sex estimation. Moreover, in the absence of skulls, it can become more complex and more difficult to estimate sex (2,3,7,9–12,14–19).…”

“…Currently, osteological, genomic, and proteomic approaches are available to estimate sex from skeletal remains and fragmented human bodies (1). Revolutionary progress has been made in DNA analysis, which has been used as a genomic method in recent years, but the degraded DNA or the absence of a DNA laboratory are the limitations in this method (17). In general, osteological methods are preferred, but there are also limitations in osteological methods due to reasons such as cremation and secondary burial (1).…”

“…However, it is highly subjective and requires experience. The morphometric method, on the other hand, is objective and reproducible, and gives more accurate results than morphological methods; moreover, it gives results specific to the population (2,9,11,12,17,20). Different morphological and morphometric data of sexual dimorphism have been reported in most population-specific studies (18,19,21,22).…”

Background Nowadays, data on the anthropometric measurements of populations is needed in many areas, especially forensic and legal. Using various methods, researchers obtain various data such as race, sex, and age, and thus provide identification of the material used. Morphological or metric methods are often used for identification. Purpose To evaluate the usefulness of the results of skull measurements using computed tomography (CT) to determine sex in a Turkish population. Material and Methods We analyzed 300 male and 300 female CT images of Turkish individuals with an age range of 21–50 years. Maximum cranial length, maximum cranial breadth, bimastoid diameter, bizygomatic diameter, and bigonial breadth were measured by CT tomography. All data were subjected to discriminant function analyses for estimating sex. Intra-observer and inter-observer variances of the measurements were examined using intraclass correlation coefficient analysis. Results Discriminant function analysis indicated that there was a significant difference between male and female with 88% accuracy. Discriminant function for estimation of sex was obtained with satisfactory accuracy rates for the parameters used. Conclusion This study confirms that skull measurements show sexual dimorphism in the Turkish population, and also suggests that it may be useful to use CT to assess skull anthropometric measurements.

Background Estimation of sex of the skeletal remains plays a vital part in the identification of an individual. This study is focused on the morphometric measurements of the foramen magnum region and examining the accuracy of sexual dimorphism in the Nepalese population. Methods Measurements were obtained from 3D computed tomography (CT) scan of 261 Nepalese adult cranial bases with known age and sex. Length and breadth of the foramen magnum, length and breadth of right and left occipital condyles and maximum and minimum intercondylar distance were measured on the base of the skull CT images. Results The mean values for all parameters were higher in males than females except for the maximum intercondylar distance. Sex prediction done with discriminant function analysis could classify the skull with an overall accuracy of 70.5%–71%. Conclusions It can be concluded from the results that the morphometric study of the foramen magnum is less reliable for sex estimation in the Nepalese population.
