“…Several authors have evaluated the maxillary, frontal, and sphenoid sinuses, relating them to possibilities of human identification with extraoral radiographs (Riepert et al, 2001;Pfaeffli et al, 2007;Silva et al, 2009) and CT scans (Perella et al, 2003;Pfaeffli et al, 2007;Tatlisumak et al, 2008;Uthman et al, 2010). Gioster- Ramos et al (2021) point out that the uniqueness of their structures individualizes people, thus paranasal sinuses can be used for human identification. Currently, the use of CT allows three-dimensional analyses, which greatly enriches and increases the resources available from Forensic Sciences and helps justice and society to establish the human identity.…”

“…The results of the study by Özer et al (2018) showed that the SS can be used to estimate the sex and age of human remains, as well as determine age-related changes and population differences. Considering the Brazilian population and the sphenoid sinus to identify individuals, Ramos et al (2021) performed linear and volumetric measurements of the SS with CBCT and concluded that these measurements are useful to characterize the sex of individuals.…”

The characteristics of the paranasal sinuses (maxillary, frontal, sphenoid and ethmoid sinuses) are information of great relevance to Forensic Sciences, as their images can be used for human identification purposes. Due to their particularities, the paranasal sinuses provide valuable information for human identification, reducing the risk of errors during investigation by experts. Such structures are visualized from several imaging exams. This study evaluates the possibilities of human identification through the analysis of the paranasal sinuses, as well as the effectiveness of their analysis in estimating sex, age and ancestry. A comprehensive search was performed in the PubMed, SciELO, LILACS, and Web of Science databases. As inclusion criteria, texts that addressed the subject were selected. Imaging analysis of the frontal, maxillary and sphenoid sinuses is a useful tool for human identification, as well as for estimating sex, age and ancestry; usually provides a high level of accuracy. Regarding the ethmoid sinus, research is indicated to verify its use in human identification, as no publications on this specific subject were found. Additional research must be carried out (especially three-dimensional analysis of the paranasal sinuses), to develop standardized protocols, improving the work of experts, helping justice and society.

“…Its intricate morphology can be divided into four main parts: the body, greater wings, lesser wings and pterygoid processes, bone structures that house and protect the brain (Er et al, 2020;Roomaney et al, 2021). Besides that, the sphenoid bone has several anatomical details such as channels, fissures and foramina that allow the passage of nerves, arteries and veins (Ramos et al, 2021;Roomaney et al, 2021) that not always evident on bidimensional images. However, with the development of Cone Beam Computer Tomography (CBCT), an image exam that allows visualization in 3 dimensions, it became easier to visualize subtill anatomical details and relationships between the analyzed structures (Singh et al, 2021).…”

The main goal of this study was to reconstruct three-dimensionally (3D) the sphenoid bone of adolescents with the software Materialise Mimics to test the accuracy and reliability of craniometric measurements performed with the software. The study was conducted according to Strengthening the Reporting of Observational studies in Epidemiology (STROBE) guidelines. Cone-Beam Computed Tomography (CBCT) was performed in adolescents before the orthodontic treatment as part of the orthodontic records. The CBCT images were exported as DICOM (Digital Imaging and Communication in Medicine) files, in a universal format, with a voxel size of 0.3 mm and sphenoid bone was three-dimensionally rendered with Software Materialise Mimics. Ten sphenoid measurements were performed in triplicate by two trained examiners. The studied population was composed of 26 adolescents, 16 females (61.5%), and 10 males (38.5%) with a mean age of 12.5 years (SD= 1.7). 60 measurements were taken and the intra and inter-examiner accuracy revealed a high degree of data reproducibility (Kappa test higher than 0.90). The reconstruction and rendering of the images obtained by CBTC allowed anatomical details of the sphenoid bone to be measured with very high reproducibility. The Software Materialise Mimics allows you to analyze anatomical structures in detail and presents useful tools to optimize craniometry analyses.

“…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).…”

“…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)(10)(11)(12)(14)(15)(16)(17)(18)(19).…”

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.
