“…Dong et al [7] found that with the measurements obtained from CT images of the mandible, the sex determination rate was 84.2%. Jain et al [12] showed that from the measurements of mastoid triangle and opisthion-bimastoid triangle, asterion-mastoidale length has an 80% and mastoid breadth has a 75% determination rate. In the study of Akhlaghi et al [1], where they reviewed the frontal sinus parameters from paranasal sinus CT images, they found that the left frontal sinus maximum height has a 61.3% determination rate.…”

As a result of our study, the metric data we obtained will be useful in cases where the skeletons' sex could not be determined by any other methods. We believe that, our study may be useful for other studies in determining of sex from foramen magnum. Our measurements could give some information of the normal ranges of the foramen magnum in normal population, so that this can contribute to the diagnosis process of some diseases by imaging.

“…Several measurements of the skull such as the length, height, and circumference of the head, mastoid process, occipital condyle, and foramen magnum (FM) have been used for this analysis in previous studies (4)(5)(6)(7)(8)(9)(10). The FM is a three-dimensional aperture within the basal central region of the occipital bone (11) and also is a transition zone between the spine and skull.…”

The aim of this study was to perform morphometric analysis of the foramen magnum (FM) using cone-beam computed tomography (CBCT). Materials and methods:This study included CBCT images of 190 individuals (88 males and 102 females). The sagittal and transverse diameters and circumference of the FM were measured. The shape of FM was classified as round, hexagonal, oval, egg-shaped, tetragonal, pentagonal, irregular A, and irregular B. The data were statistically analyzed with chi-square and t-tests to assess the level of significance for sex and age. Results:The means of its sagittal and transverse diameters and also circumference were higher in males than in females. Statistically significant differences were found between males and females for all variables (P < 0.05). No statistically significant difference (P > 0.05) was found between age groups for all variables. The round type was the most common, in 21.6% of the patients. Conclusion:CBCT images can provide valuable information regarding FM and the measurements of its sagittal and transvers diameters and also its circumference may be reliably used for sexual dimorphism in anthropometric analysis and forensic medicine.

“…Failure to replicate the initial successful results could be related to the position of asterion, one of the landmarks employed, which is highly variable among populations and individuals (Day and Tschabitscher, 1998;Sripairojkul and Adultrakoon, 2000;Mwachaka et al, 2010). Methodological differences related to instrumentation are another potential source of error (Kemkes and Gobel, 2006;Saini et al, 2012;Deepali et al, 2013;Jain et al, 2013;Jaja et al, 2013), as the original work was based on xerography (de Paiva and Segre, 2003) and did not address the possibility of variation related to positioning of the skull on the copying device (e.g., different distances between the copy machine and the mastoid; Stephan, 2014).…”

Evaluating sexual dimorphism in the human mastoid process: A viewpoint on the methodology

et al. 2015

View full text Add to dashboard Cite

The mastoid process is one of the most sexually dimorphic features in the human skull, and is therefore often used to identify the sex of skeletons. Numerous techniques for assessing variation in the size and shape of the mastoid process have been proposed and implemented in osteological research, but its complex form still presents difficulties for consistent and effective analysis. In this article, we compare the different techniques and variables that have been used to define, measure, and visually score sexual dimorphism in the mastoid process. We argue that the current protocols fail to capture the full morphological range of this bony projection, and suggest ways of improving and standardizing them, regarding both traditional and 3D-based approaches.
