“…The exact distinct anatomical borders of the frontal sinus might not be clear on 2D radiographs due to shot angle, distance and adjacent anatomy [22,23] which was expected to decrease the credibility of the research results and may be a reason for reduced interobserver agreement. Despite of that, statistical analysis for each observer revealed the same end results which gives credibility to the results.…”

Aim: To develop and assess a new protocol proposed for sex determination using frontal sinus index measured from two dimensional lateral cephalometric radiographs. Materials & Methods:The frontal sinus index was measured by two experienced radiologists and one experienced orthodontist on two hundred and one cephalometric scans (93 males & 108 females). The maximum height and width of the sinus were measured then the height to width ratio was calculated. The mean height to width ratio of the sinus were tabulated and subjected to statistical analysis to determine the correlation to gender.Results: There was a high statistically significant difference between the frontal sinus index measured between males and females groups. Conclusion:Frontal sinus index measured on lateral cephalometric radiographs by the developed protocol could be an indicator for gender identification in Egyptians and a larger sample multicentric study is recommended.

“…[1][2][3][4][5][6]9 Previous studies have utilized two-dimensional imaging techniques to determine the applicability of paranasal sinuses to determine gender and age. Luo et al 11 explored gender determination by estimating the area of the frontal sinus on lateral cephalograms of 475 patients and found that, when combined, the parameters of the frontal sinus index and area predicted gender in 76.6% of the cases. Sidhu et al 12 measured the area of the MS and its perimeter using lateral cephalograms of 50 patients, reporting a predictive accuracy of 76%.…”

This study aimed to analyze the applicability of maxillary sinus (MS) and sphenoid sinus (SS) volumes in determining gender and age. Materials and Methods:This retrospective study included cone beam computed tomography images of 164 MSs and 164 SSs of 82 patients (40 females and 42 males). Right, left, and total MS and SS volumes were estimated. The independent samples t-test, logistic regression, and Pearson correlation coefficient were used to explore their accuracy in determining age and gender.Results: Males had greater right SS, average, and total SS volumes than females (p=0.007, p=0.013, and p=0.013, respectively). The right SS volume had the best predictive power (65.9%) for gender. A regression formula using this parameter alone showed satisfactory accuracy. No significant correlations were found between age and MS or SS volumes (p>0.05). Conclusions:The SS volume is a valuable tool in determining gender, whereas neither MS nor SS are reliable predictors of age. A simple gender determination is possible with our regression formula using the right SS volume. Further studies are needed to investigate the role of paranasal sinus volumes with a view to develop formulations in determining age and gender in different populations.

“…Since the first studies applying discriminant functions to linear measurements on skulls (Giles & Elliot, 1963; Uytterschaut, 1986), many authors have felt the need to find new quantitative methods to distinguish between sexes (i.e. Luo, Wang, Zhang, & Congbo, 2018; Small, Schepartz, Hemingway, & Brits, 2018; Suazo Galdames, Perez Russo, Zavando Matamala, & Luiz Smith, 2009). Among them, a number of scholars opted for a GM approach, and applied it to mandibles (Franklin et al, 2007), pelves (Bytheway & Ross, 2010; Rmoutilová et al, 2017), and skulls (Bigoni et al, 2010; Gonzalez et al, 2011; Kimmerle et al, 2008; Pretorius et al, 2006).…”

Objectives: We analyzed the main anatomical traits found in the human frontal bone by using a geometric morphometric approach. The objectives of this study are to explore how the frontal bone morphology varies between the sexes and to detect which part of the frontal bone are sexually dimorphic. Materials and methods: The sample is composed of 161 skulls of European and North American individuals of known sex. For each cranium, we collected 3D landmarks and semilandmarks on the frontal bone, to examine the entire morphology and separate modules (frontal squama, supraorbital ridges, glabellar region, temporal lines, and mid-sagittal profile). We used Procrustes ANOVAs and LDAs (linear discriminant analyses) to evaluate the relation between frontal bone morphology and sexual dimorphism and to calculate precision and accuracy in the classification of sex. Results: All the frontal bone traits are influenced by sexual dimorphism, though each in a different manner. Variation in shape and size differs between the sexes, and this study confirmed that the supraorbital ridges and glabella are the most important regions for sex determination, although there is no covariation between them. The variable size does not contribute significantly to the discrimination between sexes. Thanks to a geometric morphometric analysis, it was found that the size variable is not an important element for the determination of sex in the frontal bone. Conclusion: The usage of geometric morphometrics in analyzing the frontal bone has led to new knowledge on the morphological variations due to sexual dimorphism. The proposed protocol permits to quantify morphological covariation between modules, to calculate the shape variations related to sexual dimorphism including or omitting the variable size.
