“…In the research done by Bassil-Nassif et al [37], an analysis of the dimorphism between the sexes in the volume of the facial cavities, including the orbital cavity, was also performed. The research results showed that the volume of the cranial cavity was significantly higher in male skulls than in female skulls, but the ratio of the volume of cranial cavities did not show significant differences between sexes [37].…”

Background. Understanding the anatomy and morphological variability of the orbital region is of great importance in clinical practice, forensic medicine, and biological anthropology. Several methods are used to estimate sex based on the skeleton or parts of the skeleton: classic methods and the geometric morphometric method. The objective of this research was to analyse sex estimation of the orbital region on a sample of skulls from a Bosnian population using the geometric morphometric method. Materials and Methods. The research was conducted on three-dimensional models of 211 human adult skulls (139 males and 72 females) from the Osteological Collection at the Faculty of Medicine in Sarajevo. The skulls were recorded using a laser scanner to obtain skull 3D models. We marked 12 landmarks on each model to analyse sexual dimorphism. Landmarks were marked using the program Landmark Editor. After marking the landmarks, we used the MorphoJ program to analyse the morphological variability between male and female orbital regions. Results. After Procrustes superimposition, generating a covariant matrix, and introducing sex as a variable for classification, a discriminant functional analysis (DFA) was applied which determined the estimation for males with 86.33% accuracy and for females with 88.89% based on the form of the orbital region. The results of regression analysis showed that the size of the orbital region has a statistically significant effect on its shape’s sexual dimorphism. After excluding the influence of size and providing DFA, we concluded that sex estimation was possible with 82.01% accuracy for males and 80.55% accuracy for females based on the shape of the orbital region in the examined sample. Conclusion. Sex estimation based on the orbital region was possible with more than 80% accuracy for both sexes, which is a high percentage of correct estimation. Therefore, we recommend using the orbital region of the skull for sex estimation.

“…Volumetric analysis of CBCT slices with the software used in the present study has been described as a highly accurate method of analyzing volumetric changes [32]. The 3D acquisition scanners and software of the system facilitated calculating volumes while eliminating the risk of error-inherent distortions and expansions of radiological images.…”

“…However, these studies differ in radiographic methods, using panoramic radiographs [18, 22-24, 29, 33], computed tomography (CT) [9,21,23,26] or cone beam computed tomography (CBCT) [8,22,32,34].…”

Aim The aim of this retrospective study was to quantify three-dimensional (3D) volumetric bone changes over a two-year period in maxillary sinuses augmented with a mineralized cortical bone allograft material (MCBA) material. Patients and Methods Eleven patients (6 males and 5 females) with mean of age of 51.6 (range: 46-61) years were treated to increase the vertical dimension of the alveolar crest by maxillary sinus floor augmentation procedure. Study data were collected from patient records and by analyzing preoperative radiographs and cone beam computed tomography (CBCT) scans taken within the first two weeks after maxillary sinus lift (T0), immediately before implant placement four months after grafting (T1), and after one year of implant loading (T2). All DICOMformatted images were rendered into volumetric images using software that automatically calculated the volume of the grafted material in cubic centimeters. Results Mean graft volume was 16.24 ± 1.54 cm 3 at T0, 14.48 ± 1.48 cm 3 at T1 and 13.06 ± 1.39 cm 3 at T2. Mean volume retraction resulted in 1.76 ± 0.34 cm 3 DV1 (T0-T1) and 1.42 ± 0.4 cm 3 DV2 (T1-T2) and was 10.83 % of the initial total volume at (T0-T1) and 9.8 % of the total volume (T1-T2). Conclusion The present retrospective investigation demonstrated a 20.63 % decrease in graft volume. Volumetric 3D assessment of CBCT scans with the selected software appeared to be a promising approach to quantifying longterm changes in the grafted area.

“…Bassil-Nassif et al [9,10] studied different facial volumes in an adult population according to the vertical facial growth pattern and identified sexual dimorphism effect on various volumetric measurements. ey advocate the existence of a compensatory mechanism among the three facial dimensions to equilibrate an excess or deficit of the vertical dimension maintaining constant the total facial volume.…”

Objectives: The objectives of the study were to evaluate the nasomaxillary complex (NMC) measurements before and following rapid maxillary expansion (RME) compared to normal subjects. Materials and Methods: Thirty consecutive patients (14 males and 16 females) with a mean age of 9.5 ± 1.8 years for males and of 11.8 ± 1.7 years for females, who underwent RME to correct their posterior unilateral or bilateral crossbite, were selected. Computed tomography (CT) scans done before treatment (BT) formed the Group BT and those after treatment constituted the Group AT. An untreated normal sample (Group NC) presenting a normal transverse occlusion and needing a cone beam CT for other purposes was formed by 30 subjects (14 males and 16 females) with a mean age of 10 ± 0.9 years for males and of 11.6 ± 1.0 years for females. The CT scans were compared between both groups BT and AT with Group NC and measurements were performed on scanned images. The mean differences between measurements were compared using the t-test (α = 0.05). Results: No significant differences in volumetric measurements representing the NMC were found between groups BT and NC. By comparing Group AT to NC, we found that all volumetric variables displayed statistically significant differences with an increase of those of Group AT. Linear transverse variables were increased in Group NC compared to Group BT and their differences were statistically significant. However, the same variables were larger in Group AT compared to Group NC. Conclusion: RME produces an increase of the NMC dimensions compared to normal controls, which supports the principle of overcorrection, needed to compensate the post-treatment relapse.
