![]() ![]() Este estudio tuvo como objetivo evaluar el valor diagnóstico de las dimensiones de los senos esfenoidales para la determinación del sexo utilizando imágenes de resonancia magnética en individuos adultos chinos. Como la mayoría de los huesos utilizados para la determinación del sexo se recuperan en un estado incompleto, a menudo es necesario utilizar huesos recuperados intactos, por ejemplo, el seno esfenoidal. La determinación del sexo de personas desconocidas juega un papel importante en la ciencia forense. KEY WORDS: Forensic science Sphenoid sinus MRI Sex determination It suggested using MRI in forensics science thus obviating the complete dependence on the usage of conventional computed tomography (CT) and facilitating the study of forensic anatomy at the level of soft tissue. This study proposed the importance of sexual dimorphism of sphenoid sinus dimensions, especially if other methods are not available. The predictive accuracy rate of the sphenoid sinus to identify sex was 63.6 % in males and 62.9 % in females with an overall accuracy of 63.3 %. Comparison between male and female groups showed significant statistical differences regarding the height, anterior-posterior diameter, area, and perimeter of sphenoid sinuses. All data were subjected to descriptive and discriminative functional analysis with unpaired t-test and canonical discriminant. ![]() The height, anterior-posterior diameter, area, and perimeter were measured in the midsagittal view of the sphenoid sinuses. MRI images of 79 sphenoid sinuses (from 44 men and 35 women) were retrospectively selected. This study aimed to evaluate the diagnostic value of sphenoid sinuses dimensions for sex determination using Magnetic Resonance Imaging (MRI) images in Chinese adults. ![]() As most bones used for sex determination are recovered in incomplete state, it is often necessary to use bones that are recovered intact e.g., the sphenoid sinus. Sex determination of unknown persons plays an important role in forensic science. ![]()
